compile error with gcc-4.0.2 on ubuntu

[Michael]

Hi all

I tried to compile the last ocplot svn-version, 9.4.2006, with gcc-4.0.2 on ubuntu..

autoreconf works
./configure works and shows everything o.k.
make doesn't work
following error messages appears:

octplot-FTVectoriser.o: In function `FTVectoriser::MakeMesh(double)':
FTGL/FTVectoriser.cpp:184: undefined reference to `gluNewTess'

Thanks for help

This does not look like a problem in gcc, rather it looks like you are missing the glu library. check if you have it installed -- note -- you will need the development package.

[Michael]

I have installed something like:
GL/gl.h
GL/glu.h

libglu1-mesa-dev...

maybe the version is to old..
which are you using?

Michel

[Shai Ayal]

You are missing glut, not glu. So the appropriate magic words are (at least for my debian):

apt-get install freeglut3-dev

thanks for this tip...
it isn't it.. still the same errors...!
maybe I will check, waht all is installed on cygwin... but not the next 4 days
Michael

[Michael]

actualy, I have installed glut.h and also freeglut.h
also something like glut.H

are you using some special parameters for ./configure?

[Shai Ayal]

nothing special for configure. I think your problem is not missing headers but missing libraries. Anyway, this is what my octplot on debian is linked against:

[Michael]

linux-gate.so.1 doesn't exist of course..
all others exist..
but the libX11.so.6, libGLU.so.1 & libGL.so.1 aren't in the /usr/X11R6/lib directory.. they are in the /usr/lib directory.. but I don't think that this is the problem... but it's of course strange...

I will do some more tests..

thanks again

[Michael]

ok, I have seen the error... the directories are essential..

thanks again

[Shai Ayal]

Michael,

Can you please write some more on how you solved this so that others which might need this info will benifit?

Shai

[Michael]

of course I can, when I have solved it... my try was not successfull!!

in ubuntu 5.1 is no package which provide /usr/X11R6/lib/libGLU.so.1

take one from the older version doesn't work ...
I have to search further..

[Michael]

I found the solution

autoreconf
./configure LDFLAGS="-lGLU -lGL -lglut"
make

l is a no I(i) it is a small L  :-(

Michel

[Shai Ayal]

This seems strange -- why does configure not find the correct libraries? at least the fltk-config should find the right OpenGL libraries.

can you try:

fltk-config --use-gl --ldflags

and
ldd octplot

[Nobody/Anonymous]

also the same problem with gcc-3.4 ...
I could not found a solution ...
till now..
