[Gmsh] Problems encountered compiling Gmsh with OpenCascade support on Windows

[Nicolas.Saugnier at loria.fr]

Hi!

I've been trying to build Gmsh on Windows with OpenCASCADE support,  
and I'm runnig into a few problems:

  Here is the configuration I used :

ENABLE_GUI=0
ENABLE_BLAS_LAPACK=0
ENABLE_PARSER=1
ENABLE_POSTPRO=1
ENABLE_TETGEN=0
ENABLE_NETGEN=0
ENABLE_METIS=0
ENABLE_OCC=1
ENABLE_MED=0


I used Visual C++ express 2008 on Windows XP Pro 64bits, with a  
default install of OpenCascade 6.3.0 and the nightly package sources  
20090615.

- in the topmost Makefile:
   GMSH_EXTRA_VERSION = "-cvs-20090615"
   The double quotes seams to be the origin of an error when  
generating GmshVersion.h, as the resulting version number was :
"2.3.1"-cvs-20090615""
  Removing them in the Makefile allowed me to go further.


- in variables.msvc, the relative path for OCC libs did not match the  
one of the OCC installation (I used a default OCC installation):
ifeq (${ENABLE_OCC},1)
   FLAGS+=/DHAVE_OCC /DHAVE_NO_OCC_CONFIG_H /DWNT /I${OCC_PREFIX}/inc
   GMSH_LIBS+=${OCC_PREFIX}/win32/bin/*.lib
endif

I modified the corresponding line to:
   GMSH_LIBS+=${OCC_PREFIX}/win32/lib/*.lib


- and in the 20090618 version of the nightly sources :

gmake.exe[1]: Entering directory `C:/Gmsh_stuff/gmsh-2.3.1-cvs-20090618/Geo'

In the meantime, I switched to a Linux plateform, where I also had a  
few problems, i'll put it in an other thread.
Hope this can be of use to you.
