Hi
Thanks David for your reply.
I extracted the sources using "java -verbose -jar -setup.jar" as ./install.csh didnt work for some reason. Any way the installation GUI came up and I selected the source files for installation and nothing else. Now following the procedure set out in the gmsh README.occ I define:
export CC="gcc -mno-cygwin -DWNT=1 -DWIN32 -DHAVE_NO_DLL"
export CXX="g++ -mno-cygwin -DWNT=1 -DWIN32 -DHAVE_NO_DLL"
as I'm using MingW/Msys
I then go to OpenCASCADE/ros for the next step:
./configure --prefix=/usr/local/opencascade --enable-debug=no
--enable-production=yes --enable-static=yes --enable-shared=no --disable-dependency-tracking
However there is no configure file to run it nor makefiles as expected (see gmsh, gsl, fltk). Sorry for my repeated posts, the history of which shows that I'm floundering a bit here and likely out of my depths. None the less would someone be able help me with this problem?
Much appreciated
Gustav
