Bug #: 53798
Summary: [4.7] Bootstrap fails on Linux x86_64 with pre-built
libmpc/mpfr/gmp due to multilib path problem
Classification: Unclassified
Product: gcc
Version: 4.7.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: windw...@gmx.com
GCC 4.7.1 fails to bootstrap on Linux x86_64 due to a multilib problem if
pre-built libraries for MPC, MPFR and GMP are used and their installation
directory is set using --with-[mpc|mpfr|gmp] (see output at the end).
Obviously these libraries reside in different paths for 32 bit and 64 bit.
The main configure script (line 5108 and following) evaluates the
--with-[mpc|mpfr|gmp]=PATH parameters and extends $gmplibs with "-LPATH/lib".
The resulting GMPLIBS is used in ./Makefile.in and ./gcc/Makefile.in, and
causes the bootstrapping to fail in either 32 or 64 bit multilib stage
(depending on the parameters).
Besides the redundancy if all libraries reside in the same path, $gmplibs can
only be correct for either 32 or 64 bit.
Workaround:
Assumption: 32 bit libraries reside in PATH/lib, the 64 bit versions in
PATH/lib64
Use --with-[mpc|mpfr|gmp]=PATH and add --with-gmp-lib=PATH/lib64.
The configure script will generate GMPLIBS with (at least) -LPATH/lib64 and
-LPATH/lib. GNU ld will ignore the incompatible version while searching for
lib[mpc|mpfr|gmp].
