--- Comment #4 from Yves Caniou <yves.can...@ens-lyon.fr> ---
I have the same issue with gcc-4.8.2 compiling gcc-4.8.2, on a Intel(R) Xeon(R)
CPU E5-2630 0 @ 2.30GHz.
First, compiling 4.8.2 from 4.7.2 (debian): no problem.
I use gmp-5.1.3, mpfr-3.1.2, mpc-1.0.1. There are not intree.
Once compiled, their respective prefix/lib are added to LD_LIBRARY_PATH.
Gcc source is copied local disk, so no NFS or such.
I call:
/tmp/YC/gcc/src-4.8.2/configure --host=x86_64-linux-gnu
--build=x86_64-linux-gnu --prefix=/home/ycaniou/bin/amd64/4.7.2/gcc
--disable-altivec --disable-fixed-point --without-cloog --without-ppl
--disable-lto --enable-nls --without-included-gettext --with-system-zlib
--enable-obsolete --disable-werror --enable-secureplt --disable-multilib
--enable-libmudflap --disable-libssp --enable-libgomp --enable-checking=release
--disable-libgcj --enable-libstdcxx-time --enable-languages=c,c++,fortran
--enable-shared --enable-threads=posix --enable-__cxa_atexit
--enable-clocale=gnu --enable-targets=all
--with-gmp=/home/ycaniou/bin/amd64/4.7.2/gmp
--with-mpfr=/home/ycaniou/bin/amd64/4.7.2/mpfr
--with-mpc=/home/ycaniou/bin/amd64/4.7.2/mpc
Everything executes well after a "make -j 8", and "make install" does its job.
Compiling 4.8.2 with the new installed 4.8.2:
. First, environment variables are updated:
library path with 4.7.2_gcc-4.8.2_prefix/lib64
CPLUS include path with 4.7.2_gcc-4.8.2_prefix/include (I also tried with in
addition include/c++/4.8.2, with same errors...)
binary path with 4.7.2_gcc-4.8.2_prefix/bin
. gmp-5.1.3, mpfr-3.1.2, mpc-1.0.1, not intree, are compiled with the
4.7.2_gcc-4.8.2 without any problem. And same steps are made: their respective
4.8.2_prefix/lib are added to LD_LIBRARY_PATH. GCC source on local disk.
I call:
/tmp/YC/gcc/src-4.8.2/configure --host=x86_64-linux-gnu
--build=x86_64-linux-gnu --prefix=/home/ycaniou/bin/amd64/4.8.2/gcc
--disable-altivec --disable-fixed-point --without-cloog --without-ppl
--disable-lto --enable-nls --without-included-gettext --with-system-zlib
--enable-obsolete --disable-werror --enable-secureplt --disable-multilib
--enable-libmudflap --disable-libssp --enable-libgomp --enable-checking=release
--disable-libgcj --enable-libstdcxx-time --enable-languages=c,c++,fortran
--enable-shared --enable-threads=posix --enable-__cxa_atexit
--enable-clocale=gnu --enable-targets=all
--with-gmp=/home/ycaniou/bin/amd64/4.8.2/gmp
--with-mpfr=/home/ycaniou/bin/amd64/4.8.2/mpfr
--with-mpc=/home/ycaniou/bin/amd64/4.8.2/mpc
And got the errors:
