And, the operating system which I am working on for doing it is Ubuntu 10.04.4 LTS 32-bit. </div><div>In order to activate "cgns" option and to specify the location of the library "hdf5", I entered the following command line from the "./build" folder I created:</div><div><br></div><div>-> cmake -DENABLE_CGNS=1 -DCMAKE_PREFIX_PATH=/home/oe/Documents/hdf5-1.8.14-linux-centos5-i386-gcc412-shared ..<br><br></div><div>As observed in CMakeCache.txt (enclosed file), the cgns option is successfully taken into account.<br></div><div>Yet I encountered numerous compilation errors in the file "GModelIO_CGNS.cpp".</div><div><br></div><div>The last discussion about this topic through gmsh mailing list dates from the fourth of april 2014, as I noticed. The conclusion was that the CGNS support should be updated/rewritten if I am not mistaken? So my question is twofold:<br></div><div><br></div><div>1. Is the current implementation of CGNS support is still under development and not usable for instance or am I doing something wrong during the compilation ? <br></div><div>2. For a geometry created and meshed through gmsh, are there any possibilities/ known utilities for making a conversion to the .cgns extension? </div><div><br></div><div> <br></div><div>Thanks in advance for any helps and responses you can provide me about this issue.<br></div><div>Kind regards, <br></div><div><br></div><div>Oguz E.<br></div><div><br></div><div>PS/ Enclosed, please find .log files and CMakeCache.txt. I would be pleased to provide more information about my issue if it is needed. <br></div><div><br></div><div><br></div><div><br></div><div><br></div></div></body></html>
