parmetis/metis lacks -fPIC

[davydden]

subj, on intel compilers.

ld: ../libmetis/libmetis.a(error.c.o): relocation R_X86_64_TPOFF32 against `gk_cur_jbufs' can not be used when making a shared object; recompile with -fPIC

[davydden]

export CFLAGS="${CFLAGS} -fPIC" should help. Maybe done locally.

[davydden]

indeed, this helped

metis/parmetis is somehow specific.
May you please export your CFLAGS before you start candi and without the patch and check if it is working? (-fPIC is needed for several packages)

[davydden]

yes, it worked with global cflags as well.

Okay, lets document this. Intel compiler getting me and others headaches (I think Timo has given up for this). Before analysing intel compilers carefully, I want to implement the configuration stuff for each package, but I need to work on some other things (which are more recent to me) firstly.
