[SOLVED] Compiling gcc 4.8.5

Issue

Im trying to compile gcc 4.8.5 under Red Hat 6. This is my procedure:

tar -xvzf archive.tar.gz

cd gcc-4.8.5

./configure --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release \
--with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object \
--enable-languages=fortran,c --prefix=/opt/gcc4.8.5

make

Then I get the following error:

make  all-am
make[4]: Entering directory `/app/gfortran_build/gcc-4.8.5/host-x86_64-unknown-linux-gnu/lto-plugin'
/bin/sh ./libtool --tag=CC --tag=disable-static  --mode=link gcc -Wall -g  -module -bindir /opt/gcc4.8.5/libexec/gcc/x86_64-unknown-linux-gnu/4.8.5   -o 
liblto_plugin.la -rpath /opt/gcc4.8.5/libexec/gcc/x86_64-unknown-linux-gnu/4.8.5 lto-plugin.lo -Wc,../libiberty/pic/libiberty.a

/usr/bin/ld: ../libiberty/pic/libiberty.a(simple-object-coff.o): relocation R_X86_64_PC32 against undefined symbol `simple_object_set_big_16' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status

I already read about CFLAGS, but I wont get it to work.

kind regards

Solution

it worked with the following:

../gcc-4.8.5/configure CC="/opt/gcc4.5/bin/gcc" --prefix=/opt/gcc4.8.5 --enable-languages=c,c++,fortran --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object

The interesting part is CC=...

The installed gcc-version is 4.4. With this version, the compiling fails.

kind regards
