> Hello,
> I'm having a problem trying to compile an application that requires
> the shared version of mpich2, the compiler was printing the following:
> ./libmpich.a(setbotf.o): relocation R_X86_64_32 against `mpifcmb2_'
> can not be used when making a shared object; recompile with -fPIC
> among other errors that look the same.
> By googling a bit, I found that I should recompile mpich2 with
> --enable-shared, however when I do, I get the same error than in my
> application, this time during the building phase of mpich! This error
> does not abort the compilation process but seems to not produce
> everything.
> I attach the log of the "make" command.
> The configure command was the following:
> ./configure --prefix=/usr --enable-fc --enable-romio --with-pvfs2=/usr
> --enable-shared
> I tried everything : putting CFLAGS="-fPIC", or CC="gcc -fPIC", etc.
> it doesn't solve the problem.
> I'm working on Debian squeeze with gcc 4.4.5.
