[Gmsh] compiling & linking with OpenCASCADE support ?

[David Colignon]

Hi Benedikt,

the configure script try to find the  libTKernel.a  library in the /lib subdirectory in the /home2/oswald/extlib/OpenCASCADE/OpenCascade_6_2_0 directory you gave it as input. But the exact location off the /lib suddirectory depends on the way you installed OCC and it could be elsewhere...

Can you check where is the  libTKernel.a  library ?

Cheers,

Dave
