[Lapackpp-devel] Help me: syntax errors from "COMPLEX" in Lapack++

[mohamad c. <moh...@in...>]

HI all,
I'm new to C++. I've just installed Lapackpp-2.0.3. The installation 
seems to be fine but when i tried to do a test (i've tried the command 
"gcc tEigSolve.cc" under the directory lapackpp-2.0.3/testing) i have 
got many syntax errors!!, these errors come from files: vc.h, gmc.h, 
lavc.h, blas1pp.h, blaspp.h and blas++.h. Most of these errors claim 
about the struct "COMPLEX", when declaring a pointer or a reference to 
"COMPLEX" saying that this is a syntax error!
Please give me some feedback,
Thanks in advances!

Dear Mohamad,

when using Lapack++ and using the complex-valued matrices, you need to 
define the constant LA_COMPLEX_SUPPORT because otherwise lapack++ would 
have the complex numbers disabled. Either you insert
#define LA_COMPLEX_SUPPORT
into your personal source code before including the headers, or you call 
gcc with -DLA_COMPLEX_SUPPORT. If you want to run the example files, you 
can have this done automatically by the command "make check".

Please send your full compile command line so that we can see how you=20
compiled your test program.

[mohamad c. <moh...@in...>]

The compile command i have used is very simple (maybe stupid) because i=20
don't know how to deal with dependencies between these files!
here its:
g++ -Wall -c tEigSolve.cc
g++ tEigSolve.o
Thank you in adavnce for any kind of help!

C++ doesn't work this way, or in other words not that simple. You need 
to get a textbook about how to use a C++ compiler, especially how to
1. specify the directories to find the header files,
2. specify the libraries to link against, and
3. specify the directories where to find the libraries to link against.

This is not a lapack++ problem but a general problem of how to write a 
C++ program that uses other libraries.

> g++ -Wall -c tEigSolve.cc

In this case you are missing the specification of where to find 
lapackpp's header files, which would usually look like this

g++ -I/usr/include/lapackpp -c tEigSolve.cc

Apart from this problem, this step obviously worked. This step is called 
"compiling" and if you report a bug, it is important to note the the 
"compiling" went ok.

> g++ tEigSolve.o

This other step obviously gave you errors. This step is called 
"linking", so you got "linker errors". The point is that your c++ 
program uses extra libraries (lapack++'s libraries in this case), and 
you must tell the linker which libraries to use and where to find it. 
For example

g++ -L/usr/lib -llamatrix++ -llapack++ -lblas++ -llapack -lblas tEigSolve.o

However, usually you don't call the compiler by hand. Instead, you use 
some Makefile which contains the compiler commands (see "info make" on 
your system). And even further, you don't even write the Makefile by 
hand, but you have them generated by automake and autoconf (see "info 
automake" and "info autoconf"). In that case, autoconf is configured by 
a top-level file called "configure.in" or "configure.ac", and 
configuration for Lapack++ use can be done through the macro 
ACX_LAPACKPP which is included in the filename acx_lapackpp.m4. That's 
how we are using this in our package simthetic-mimolib 
http://cvs.sourceforge.net/viewcvs.py/simthetic/mimolib/

[mohamad c. <moh...@in...>]

Thank you Christian,
I follow your advices and i began reading some tutorials about "automake=20
and autoconf". It will be very helpful for me if you can send me an=20
example of a configure.ac file and a Makefale.am which use the lapack++=20
library.
Thank you again and again...

[Christian S. <sti...@tu...>]

Dear Mohamad,

I am confident that you fill find plenty of documentation for these c++=20
tools. As for an example, I would mostly direct you to our package=20
package simthetic-mimolib, where you can download the configure.in and=20
Makefile.am files directly from CVS=20
http://cvs.sourceforge.net/viewcvs.py/simthetic/mimolib/ or rather=20
download a full package on=20
http://sourceforge.net/project/showfiles.php?group_id=3D89810&package_id=3D=
109380
