Dear Foamers,


recently I installed the latest version of OF v1906. Everything looked good, until decomposePar is used:


decomposePar: error while loading shared libraries: libkahip.so: cannot open shared object file: No such file or directory


So I did recompile KaHIP in the thridparty folder successfully. But it turned out "libkahipDecomp.so" is installed instead in:


Quote:
~/OpenFOAM/OpenFOAM-v1906/platforms/linux64GccDPInt32Opt/lib
Then I re-named libkahipDecomp.so to libkahip.so. I can use decomposePar but with:


Segmentation fault (core dumped).


So how do we use kaHIP to decompose fluid Domain?


-------------------------


Update:


libkahipDecomp.so is only 73.5kb in size, while the "libkahip.a" in



Quote:
/OpenFOAM/ThirdParty-v1906/KaHIP_v2.00d/deploy
is 2.7 MB. So we need make the static lib to *.so and copy to the above folder. How we do that?


Update 2:


Re-run ./Allwmake in `OpenFOAM-v1906` folder fixed the problem.
