Problem with basic includes after building

[pmalek]

I have just launched this script on Centos 6.6 x64 and gcc seemed to work but after running e.g. zsh 5.0.7 compilation I have the following:

$./configure

After installing glibc headers I add the following to your script's gcc build (--disable-multilib) because otherwise I would get an error:

gcc-*)
                # We are using a newer version of CLooG (0.18.0).
                # I have also made stack protection available
                # (similar to DEP in windows).
                CONF_ARGS=(
                    --disable-cloog-version-check
                    --disable-ppl-version-check
                    --disable-multilib

I have added the following to my .bashrc:

PATH="/home/USER/src/gcc-4.9.2-boost-1.57-master/rtf/bin:$PATH"
LD_LIBRARY_PATH="/home/USER/src/gcc-4.9.2-boost-1.57-master/rtf/lib:/home/USER/src/gcc-4.9.2-boost-1.57-master/rtf/lib64:$LD_LIBRARY_PATH"

BTW any ideas how can I install it in e.g. /usr/local/ (system wide/automatically)?Because if I launch the script in the following way:

$./bld.sh /usr/local

then instead of installing it actually there then it would create the subdirectory /usr/local/rtf and in it bin, lib, etc etc.

Thanks for the tip about --disable-multilib. I have not seen a case where it is needed. I will dig in a bit deeper to better understand what happened.

To release to /usr/local area, change line 356 from this:

RTFDIR=$"ROOTDIR/rtf"

to this

RTFDIR="$ROOTDIR"

However i would strongly encourage you not to do this. It might destabilize your system because there may be components of the OS or installed packages that rely on the version of the compiler that the OS was built with.
