[ggt-devel] Error while compiling GMTL-0.5.4 on amd64

[Vikas N K. <vik...@us...>]

Hi

I have installed Scons-1.0.0 and that installed fine on my system.

Now I am trying to compile gmtl-0.5.4  by typing "scons" and it gives
me the following error.

How do I fix this error ?

user1@computer2$ scons
scons: Reading SConscript files ...
AttributeError: 'module' object has no attribute 'options':
  File "/home/user1/libraries/gmtl-0.5.4/SConstruct", line 30:
    except AttributeError: has_help_flag = SCons.Script.options.help_msg

Please help.
Thanks
Vikas

Greetings,

Have you tried building GMTL without the cppunit tests?  The cppunit tests
are optional; if the build doesn't find them, it will build GMTL without the
CppUnit test cases.

Regards,

[ggt-devel] installing gmtl on linux

[Patrick W. <pat...@gm...>]

hello,

I've got a problem installing gmtl on my linux machine. (in order to use vr juggler)
The cppunit path and the boost path are set correctly.
When I execute scons it always claims that cppunit/extensions/MetricRegistry.h is missing.
It really isn't existing in my filesystem, so I could imagine this file isn't included in cppunit any more.
I also couldn't download the recommended version of cppunit from sourceforge, because it isn't listed for download any more. The newer versions don't have that missing file.
Currently I'm using cppunit1.12.0.
Is there a known workaround or do i have to install any additional package?

greetings, 
patrick waldschmitt

[Patrick H. <pa...@13...>]

It's possible. Feel free to add overloads that are useful to you. GMTL  
could always use more extensive coverage of different use cases.

It does :)
Thank you,

but what about the makeRot and makeTrans functions,
they're only supposed to work with a few types as well?

  VC++ gives tons more output than those 2 lines I sent you.  basically AA * vec and Euler * vec don't exist, and the tons of spew from VC++ is it's way of saying that....

  use this main.cpp, and compile with cl main.cpp -I..

  it does compile...


  #include <gmtl/gmtl.h>


  int main()

     gmtl::Vec3f myVec;

        check your compiler version.

        I have

        compiling your 3rd example, I get this error:

        main.cpp: In function `int main()':
        main.cpp:13: error: no match for 'operator*' in 'myVec * myAA'

        which makes sense, since there are no functions for that.



        Swapping the args, I still get 2 errors:

        which makes sense, since we don't have functions for AA * vec, or euler * vec   (you should use matrix or quaternion...)



        here's my main.cpp so that you can try it on your compiler.

        #include <gmtl/gmtl.h>


        int main() 

        {

                   myVec = myEuler * myVec ;

           return 0; 

        }

            what happens when you reverse your arguments?

            gmtl::Vec3f myVec;
             gmtl::AxisAnglef myAA;
             gmtl::Quatf myQuat;
             gmtl::Matrix44f myMat;
             gmtl::EulerAngleXYZf myEuler;
             
             myVec = myAA * myVec ;
             myVec = myQuat * myVec ;
             myVec = myMat * myVec ;
             myVec = myEuler * myVec ;




            I don't think it works to have the vec on the left hand side... but i could be wrong, i haven't used this library in a few years... :)

              Hello there,

              I am trying to use GMTL in my application,
              but I am running into a lot of problems.
              A lot of the examples in the FAQ do not seem to work.
              I include gmtl.h, so that should cover everything, right?

              Ok, so, where to start. First of all; extracting rotation/translation information from a matrix doesn't work properly.

              The FAQ states:

              "You can extract the rotational data as any of GMTL's rotation data types. In any case, you need to use the makeRot templated function. Note that you need to specify which rotation data type you want to extract."

              followed by four examples.

              Two of these examples do not work; extracting the rotation in euler angles or quaternions works, but trying to get axis angles or a matrix fails. 


              myAxisAngle = gmtl::makeRot< gmtl::AxisAnglef >( mymat )


              results in 19 errors on that line.

              Error 1 error C2784: 'gmtl::Coord<POS_TYPE,ROT_TYPE> &gmtl::set(gmtl::Coord<POS_TYPE,ROT_TYPE> &,const gmtl::Matrix<DATATYPE,MATROWS,MATCOLS> &)' : could not deduce template argument for 'gmtl::Coord<POS_TYPE,ROT_TYPE> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323 
              Error 2 error C2784: 'gmtl::Coord<POS_TYPE,ROT_TYPE> &gmtl::set(gmtl::Coord<POS_TYPE,ROT_TYPE> &,const gmtl::Matrix<DATATYPE,MATROWS,MATCOLS> &)' : could not deduce template argument for 'gmtl::Coord<POS_TYPE,ROT_TYPE> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323 
              Error 3 error C2784: 'gmtl::Matrix<DATA_TYPE,ROWS,COLS> &gmtl::set(gmtl::Matrix<DATA_TYPE,ROWS,COLS> &,const gmtl::Quat<DATA_TYPE> &)' : could not deduce template argument for 'gmtl::Matrix<DATA_TYPE,ROWS,COLS> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323 
              ...and so on...


              myRotationMat = gmtl::makeRot< gmtl::Matrix44f >( mymat );

              results in similar errors



              Secondly, the makeTrans function works for Point3f and Vec3f, but not for Matrix44f. The following code:

              gmtl::Matrix44f matrix1;
              gmtl::Matrix44f matrix2;
              matrix2 = gmtl::makeTrans< gmtl::Matrix44f >( matrix1 );

              results in the following errors:

              Error 1 error C2039: 'Size' : is not a member of 'gmtl::Matrix<DATA_TYPE,ROWS,COLS>' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 122

              The 3rd problem I encountered is the rotating of vectors.
              The FAQ says:
               "In most cases you can simply use the * operator with your vector and one of the rotaional data types."

              So I tried that, with the provided sample code:

               gmtl::Vec3f myVec;
               gmtl::AxisAnglef myAA;
               gmtl::Quatf myQuat;
               gmtl::Matrix44f myMat;
               gmtl::EulerAngleXYZf myEuler;
               
               myVec = myVec * myAA;
               myVec = myVec * myQuat;
               myVec = myVec * myMat;
               myVec = myVec * myEuler;


              This results in >100 errors, all of type C2784 ("could not deduce template argument for....")


              I'm clueless here, I am trying to use the GMTL library for basic math operations, but just about everything I try to do, fails.

              Can someone help me out?

VC++ gives tons more output than those 2 lines I sent you.  basically AA *

use this main.cpp, and compile with *cl main.cpp -I..*

Re: [ggt-devel] problems using GMTL

[Wouter W. <wo...@xs...>]

Oh yes, sorry, I forgot to mention that I'm using Visual Studio 2005 on windows.
If the code should compile, then this must be a VS issue... hmmmm
maybe some setting of flag somewhere, I'll look into it

    which makes sense, since there are no functions for that.



    Swapping the args, I still get 2 errors:

    which makes sense, since we don't have functions for AA * vec, or euler * vec   (you should use matrix or quaternion...)



    here's my main.cpp so that you can try it on your compiler.

    #include <gmtl/gmtl.h>


    int main()

        what happens when you reverse your arguments?

        gmtl::Vec3f myVec;
         gmtl::AxisAnglef myAA;
         gmtl::Quatf myQuat;
         gmtl::Matrix44f myMat;

         myVec = myMat * myVec ;
         myVec = myEuler * myVec ;




        I don't think it works to have the vec on the left hand side... but i could be wrong, i haven't used this library in a few years... :)

          Hello there,

          I am trying to use GMTL in my application,
          but I am running into a lot of problems.
          A lot of the examples in the FAQ do not seem to work.
          I include gmtl.h, so that should cover everything, right?

          Ok, so, where to start. First of all; extracting rotation/translation information from a matrix doesn't work properly.

          The FAQ states:

          "You can extract the rotational data as any of GMTL's rotation data types. In any case, you need to use the makeRot templated function. Note that you need to specify which rotation data type you want to extract."

          followed by four examples.

          Two of these examples do not work; extracting the rotation in euler angles or quaternions works, but trying to get axis angles or a matrix fails. 


          myAxisAngle = gmtl::makeRot< gmtl::AxisAnglef >( mymat )


          results in 19 errors on that line.

          Error 1 error C2784: 'gmtl::Coord<POS_TYPE,ROT_TYPE> &gmtl::set(gmtl::Coord<POS_TYPE,ROT_TYPE> &,const gmtl::Matrix<DATATYPE,MATROWS,MATCOLS> &)' : could not deduce template argument for 'gmtl::Coord<POS_TYPE,ROT_TYPE> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323 
          Error 2 error C2784: 'gmtl::Coord<POS_TYPE,ROT_TYPE> &gmtl::set(gmtl::Coord<POS_TYPE,ROT_TYPE> &,const gmtl::Matrix<DATATYPE,MATROWS,MATCOLS> &)' : could not deduce template argument for 'gmtl::Coord<POS_TYPE,ROT_TYPE> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323 
          Error 3 error C2784: 'gmtl::Matrix<DATA_TYPE,ROWS,COLS> &gmtl::set(gmtl::Matrix<DATA_TYPE,ROWS,COLS> &,const gmtl::Quat<DATA_TYPE> &)' : could not deduce template argument for 'gmtl::Matrix<DATA_TYPE,ROWS,COLS> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323 
          ...and so on...


          myRotationMat = gmtl::makeRot< gmtl::Matrix44f >( mymat );

          results in similar errors



          Secondly, the makeTrans function works for Point3f and Vec3f, but not for Matrix44f. The following code:

          gmtl::Matrix44f matrix1;
          gmtl::Matrix44f matrix2;
          matrix2 = gmtl::makeTrans< gmtl::Matrix44f >( matrix1 );

          results in the following errors:

          Error 1 error C2039: 'Size' : is not a member of 'gmtl::Matrix<DATA_TYPE,ROWS,COLS>' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 122

          The 3rd problem I encountered is the rotating of vectors.
          The FAQ says:
           "In most cases you can simply use the * operator with your vector and one of the rotaional data types."

          So I tried that, with the provided sample code:

           gmtl::Vec3f myVec;
           gmtl::AxisAnglef myAA;
           gmtl::Quatf myQuat;
           gmtl::Matrix44f myMat;
           gmtl::EulerAngleXYZf myEuler;
           
           myVec = myVec * myAA;
           myVec = myVec * myQuat;
           myVec = myVec * myMat;
           myVec = myVec * myEuler;


          This results in >100 errors, all of type C2784 ("could not deduce template argument for....")


          I'm clueless here, I am trying to use the GMTL library for basic math operations, but just about everything I try to do, fails.

          Can someone help me out?

Re: [ggt-devel] problems using GMTL

[Kevin M. <ke...@su...>]

*check your compiler version.
*
I have
g++ (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)

compiling your 3rd example, I get this error:

main.cpp: In function `int main()':
main.cpp:13: error: no match for 'operator*' in 'myVec * myAA'
main.cpp:14: error: no match for 'operator*' in 'myVec * myQuat'
main.cpp:15: error: no match for 'operator*' in 'myVec * myMat'
main.cpp:16: error: no match for 'operator*' in 'myVec * myEuler'

which makes sense, since there are no functions for that.



Swapping the args, I still get 2 errors:

main.cpp: In function `int main()':
main.cpp:13: error: no match for 'operator*' in 'myAA * myVec'
main.cpp:16: error: no match for 'operator*' in 'myEuler * myVec'


which makes sense, since we don't have functions for AA * vec, or euler *
vec   (you should use matrix or quaternion...)



here's my main.cpp so that you can try it on your compiler.

#include <gmtl/gmtl.h>


int main()
{
   gmtl::Vec3f myVec;
    gmtl::AxisAnglef myAA;
     gmtl::Quatf myQuat;
      gmtl::Matrix44f myMat;
       gmtl::EulerAngleXYZf myEuler;

        myVec = myAA * myVec ;
         myVec = myQuat * myVec ;
          myVec = myMat * myVec ;
           myVec = myEuler * myVec ;
   return 0;
}

  what happens when you reverse your arguments?

  gmtl::Vec3f myVec;
   gmtl::AxisAnglef myAA;
   gmtl::Quatf myQuat;
   gmtl::Matrix44f myMat;
   gmtl::EulerAngleXYZf myEuler;
   
   myVec = myAA * myVec ;
   myVec = myQuat * myVec ;
   myVec = myMat * myVec ;
   myVec = myEuler * myVec ;




  I don't think it works to have the vec on the left hand side... but i could be wrong, i haven't used this library in a few years... :)

    Hello there,

    I am trying to use GMTL in my application,
    but I am running into a lot of problems.
    A lot of the examples in the FAQ do not seem to work.
    I include gmtl.h, so that should cover everything, right?

    Ok, so, where to start. First of all; extracting rotation/translation information from a matrix doesn't work properly.

    The FAQ states:

    "You can extract the rotational data as any of GMTL's rotation data types. In any case, you need to use the makeRot templated function. Note that you need to specify which rotation data type you want to extract."

    followed by four examples.

    Two of these examples do not work; extracting the rotation in euler angles or quaternions works, but trying to get axis angles or a matrix fails. 


    myAxisAngle = gmtl::makeRot< gmtl::AxisAnglef >( mymat )


    results in 19 errors on that line.

    Error 1 error C2784: 'gmtl::Coord<POS_TYPE,ROT_TYPE> &gmtl::set(gmtl::Coord<POS_TYPE,ROT_TYPE> &,const gmtl::Matrix<DATATYPE,MATROWS,MATCOLS> &)' : could not deduce template argument for 'gmtl::Coord<POS_TYPE,ROT_TYPE> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323

    ...and so on...


    myRotationMat = gmtl::makeRot< gmtl::Matrix44f >( mymat );

    results in similar errors



    Secondly, the makeTrans function works for Point3f and Vec3f, but not for Matrix44f. The following code:

    gmtl::Matrix44f matrix1;
    gmtl::Matrix44f matrix2;
    matrix2 = gmtl::makeTrans< gmtl::Matrix44f >( matrix1 );

    results in the following errors:

    Error 1 error C2039: 'Size' : is not a member of 'gmtl::Matrix<DATA_TYPE,ROWS,COLS>' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 122

    The 3rd problem I encountered is the rotating of vectors.
    The FAQ says:
     "In most cases you can simply use the * operator with your vector and one of the rotaional data types."

    So I tried that, with the provided sample code:

     gmtl::Vec3f myVec;
     gmtl::AxisAnglef myAA;
     gmtl::Quatf myQuat;
     gmtl::Matrix44f myMat;
     gmtl::EulerAngleXYZf myEuler;
     
     myVec = myVec * myAA;
     myVec = myVec * myQuat;
     myVec = myVec * myMat;
     myVec = myVec * myEuler;


    This results in >100 errors, all of type C2784 ("could not deduce template argument for....")


    I'm clueless here, I am trying to use the GMTL library for basic math operations, but just about everything I try to do, fails.

    Can someone help me out?

[ggt-devel] problems using GMTL

[Wouter W. <wo...@xs...>]

Hello there,

I am trying to use GMTL in my application,
but I am running into a lot of problems.
A lot of the examples in the FAQ do not seem to work.
I include gmtl.h, so that should cover everything, right?

Ok, so, where to start. First of all; extracting rotation/translation information from a matrix doesn't work properly.

The FAQ states:

"You can extract the rotational data as any of GMTL's rotation data types. In any case, you need to use the makeRot templated function. Note that you need to specify which rotation data type you want to extract."

followed by four examples.

Two of these examples do not work; extracting the rotation in euler angles or quaternions works, but trying to get axis angles or a matrix fails. 


myAxisAngle = gmtl::makeRot< gmtl::AxisAnglef >( mymat )


results in 19 errors on that line.

Error 1 error C2784: 'gmtl::Coord<POS_TYPE,ROT_TYPE> &gmtl::set(gmtl::Coord<POS_TYPE,ROT_TYPE> &,const gmtl::Matrix<DATATYPE,MATROWS,MATCOLS> &)' : could not deduce template argument for 'gmtl::Coord<POS_TYPE,ROT_TYPE> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323 
Error 2 error C2784: 'gmtl::Coord<POS_TYPE,ROT_TYPE> &gmtl::set(gmtl::Coord<POS_TYPE,ROT_TYPE> &,const gmtl::Matrix<DATATYPE,MATROWS,MATCOLS> &)' : could not deduce template argument for 'gmtl::Coord<POS_TYPE,ROT_TYPE> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323 
Error 3 error C2784: 'gmtl::Matrix<DATA_TYPE,ROWS,COLS> &gmtl::set(gmtl::Matrix<DATA_TYPE,ROWS,COLS> &,const gmtl::Quat<DATA_TYPE> &)' : could not deduce template argument for 'gmtl::Matrix<DATA_TYPE,ROWS,COLS> &' from 'gmtl::AxisAnglef' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 1323 
...and so on...


myRotationMat = gmtl::makeRot< gmtl::Matrix44f >( mymat );

results in similar errors



Secondly, the makeTrans function works for Point3f and Vec3f, but not for Matrix44f. The following code:

gmtl::Matrix44f matrix1;
gmtl::Matrix44f matrix2;
matrix2 = gmtl::makeTrans< gmtl::Matrix44f >( matrix1 );

results in the following errors:

Error 1 error C2039: 'Size' : is not a member of 'gmtl::Matrix<DATA_TYPE,ROWS,COLS>' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 122 
Error 2 error C2065: 'Size' : undeclared identifier C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 122 
Error 3 error C2039: 'Size' : is not a member of 'gmtl::Matrix<DATA_TYPE,ROWS,COLS>' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 123 
Error 4 error C2039: 'Size' : is not a member of 'gmtl::Matrix<DATA_TYPE,ROWS,COLS>' C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 125 
Error 5 error C2679: binary '=' : no operator found which takes a right-hand operand of type 'const float' (or there is no acceptable conversion) C:\Program Files\VR Juggler 2.2.0\include\gmtl\Generate.h 134 


The 3rd problem I encountered is the rotating of vectors.
The FAQ says:
 "In most cases you can simply use the * operator with your vector and one of the rotaional data types."

So I tried that, with the provided sample code:

 gmtl::Vec3f myVec;
 gmtl::AxisAnglef myAA;
 gmtl::Quatf myQuat;
 gmtl::Matrix44f myMat;
 gmtl::EulerAngleXYZf myEuler;
 
 myVec = myVec * myAA;
 myVec = myVec * myQuat;
 myVec = myVec * myMat;
 myVec = myVec * myEuler;


This results in >100 errors, all of type C2784 ("could not deduce template argument for....")


I'm clueless here, I am trying to use the GMTL library for basic math operations, but just about everything I try to do, fails.

Can someone help me out?

Did you run the GMTL test suite with the above change? It looks to me lik=

tests are already used to verify that the distance calculation returned b=

[ggt-devel] Bug in PlaneOps.h determining nearest point

[Eron S. <es...@dg...>]

findNearestPt for planes does not properly calculate the distance of the 
point to the plane.  It should be done as:

    DATA_TYPE dist_to_plane = distance(plane, pt);

You can pass the -Wno-strict-aliasing flag to gcc.

[ggt-devel] Compiler warnings

[Kevin G. <go...@gm...>]

Hello.

I'm compiling a VR Juggler app against GMTL version 0.5.4 using g++
version 4.1.3, and I'm getting the following warnings:

/usr/local/include/gmtl-0.5.4/gmtl/Math.h: In function 'float
gmtl::Math::fastInvSqrt(float)':

/usr/local/include/gmtl-0.5.4/gmtl/Math.h:405: warning: dereferencing

Is there a way to disable this particular warning for this particular
GMTL header file (assuming that it's safe to ignore the warning)?

Thanks!

That's great!
I tried with the new SConstruct file, it really works.

Thanks a lot!
