Hello Walid,

You probably installed a 64bit Linux OS on your new Opteron. Many
distributions come with both 32bit and 64bit libs but here, the linker
cannot find the 32bit /usr/lib/libm.a when compiling abinit in -default-
32bit.
There are 2 solutions:
x install the missing 32bit libm.a - on my RedHat EL5, this means
install the glibc-devel.i386 package; your distro has probably a similar
way.
x compile abinit in 64bit and link with 64bit libraries by configuring
with --enable-64bit-flags

Cheers,


Alain
