Hi Jed,
I tried both ways and still get a compiler error, but this time I think
it is the -g option:
CLINKER
/share/apps/petsc-petsc-7cd361a5361c/linux-gnu-debug/lib/libpetsc.so.3.04.4
/usr/bin/ld:
/share/apps/open64/lib/gcc-lib/x86_64-open64-linux/4.2.4/libopen64rt.a(cacheinfo.o):
relocation R_X86_64_32S against `a local symbol' can not be used when
making a shared object; recompile with -fPIC
/share/apps/open64/lib/gcc-lib/x86_64-open64-linux/4.2.4/libopen64rt.a:
could not read symbols: Bad value
Looks like this compiler claims to be able to link with shared
libraries, but in fact cannot (since no shared version of libopen64rt.a
is available). Configure --with-shared-libraries=0 to get a static
build of PETSc.
There was a discussion about this on petsc-maint a couple of years ago with a
reference to
http://devgurus.amd.com/thread/159277
i.e the compiler links to libopen64rt_shared.a when -shared options is
specified.
But we detect the compiler libraries libraries without using '-shared'
Workarround discussed at that time:
--with-shared-libraries=1 --with-clib-autodetect=0
--with-fortranlib-autodetect=0 LIBS='-lfortran -lmv -lffio'
[but we mignt need --with-cxx-autodetect=0 aswell [with -lstdc++ in LIBS]
Would we have more or less failures if we used the Fortran linker and
passed -lstdc++ when needed (with no other autodetect)? I hate
second-guessing the compilers.
Whenever we make such assumptions - there is always a corner case
where something else fails.
[the current issue is an example of one such assumption.]

This is something we should be able to detect in our configure tests.
