[petsc-users] Compile petsc with bgclang compilers on mira/vesta?

[Satish Balay]

looks like '-fPIC' with clang is causing problems. The following works for me.

./configure --with-cc=mpicc --with-cxx=mpic++11 --with-fc=0 --with-clib-autodetect=0 --with-cxxlib-autodetect=0 --with-shared-libraries=0 --download-f2cblaslapack=1
