Hi,
I get this error:
fortran/arith.o: In function `gfc_mpfr_to_mpz(__mpz_struct*,
__mpfr_struct*, locus*)':
arith.c:(.text+0x1169): undefined reference to `mpfr_get_z_2exp'
The system is running Scientific Linux 6.2 with the standard libmpfr
package, mpfr-2.4.1-6.el6.x86_64, installed.
Thereis no mpfr_get_z_2exp in /usr/lib64/libmpfr.so.1.2.0, although
there is mpfr_get_z_exp in it.
Is the prerequiste mpfr-2.4+ correct? Or do I need a later version the
the mpfr library?
Thanks,
Ron

GCC 4.8 requires MPFR 2.4.2 or later. This is documented at
http://gcc.gnu.org/install/prerequisites.html .

Go into the top-level gcc srcdir and type:
./contrib/download_prerequisites
