Hi.
I'm trying to package petsc 2.3.3, but I didn't understand the logic
of some options, in particular for umfpack. E.g. If I specify at the
config stage:
--with-umfpack-lib=[${_libdir}/libumfpack.a,${_libdir}/libamd.a]
and the ${_libdir} path contains both shared and static libraries then
the linking command are expanded to:
-lumfpack -Wl,-rpath,<path of petsc> -lamd
Ditto if I specify:
--with-umfpack-lib=[libumfpack.a]
they are expanded to the two libs "-lumpack -lamd" (i.e. it guesses the
other lib "libamd" even if I don't specify). So what is the logic behind the
--with-xxx-lib
option? Should I specify just the list of comma separated libraries
enclosed in '[...]' pair? And how to force the usage of static libraries
when both shared and static exists? Because in other cases I see it
could be specified also the linking command. E.g., if I have a
system-wide lapack library, I could use:
--with-lapack-lib=[-llapack]
but this sound working in some option and not in some other. So what
is the "right way"?
Thanks in advance for any help.
Bye
Giuseppe.
