<br>
</div>I think CMakeLists.txt was mainly set up for use by<br>
$PETSC_DIR/config/PETSc/packages/parmetis.py, but the modifications seem<br>
to have mainly been to use METIS and GKlib without the hack of<br>
symlinking in the build directory.<br>

<br>
</div>No, but it expects METIS to be built (and specified using METIS_PATH; it<br>
looks like a bug in parmetis.py that it can link the wrong libmetis.so).<br>

</div>Yes, moving the thread and Cc'ing people who may be interested.<br>
</blockquote></div><br></div><div class="gmail_extra">I have been experimenting with having Clique checkout both pkg-metis and pkg-parmetis as part of its build system and it seems that a few things need to be added to the parmetis CMakeLists.txt for it to function correctly (please correct me if I am missing something!).<br>
<br></div><div class="gmail_extra">The two main problems are the inclusion of gklib_tls.h and gklib_defs.h, where the former is generated by the metis build system, usually in metis/include in the installation directory, and the latter is is in metis/libmetis/ in the source directory. While setting METIS_PATH to the metis installation directory would pick up gklib_tls.h since ${METIS_PATH}/include is added to the include directories of the parmetis CMakeLists.txt, I do not see any corresponding include_directories statement for the libmetis directory containing gklib_defs.h. Furthermore, I'm not sure if a sufficient number of headers are installed by metis for the parmetis build to succeed if METIS_ROOT is set to the installation directory (but I could be wrong).<br>
