[petsc-users] error when trying to compile with HPDDM

[Alfredo Jaramillo]

Hi Pierre, no, I don't really need that flag. I removed it and the
installation process went well. I just noticed a "minor" detail when
building SLEPc:

"gmake[3]: warning: jobserver unavailable: using -j1.  Add '+' to parent
make rule"

so the compilation of that library went slow.

Thanks,
Alfredo
