install g++ without update glibc - linux

Question

I need to compile a c++ project with glibc 2.13 version. I found out that Ubuntu 11.10 has the verison of the glibc that i'm searching.
So i installed it in my virtual machine, and then i installed g++ compiler with:
sudo apt-get install g++
The problem is that g++ package updates also glib to the lastest version of glibc 2.19.
I tried also to compile the source of glibc2.13 but i get different errors in compiling, because for sure i need to use the same version of compiler used when it was been created.
I think that the fastest way is to use glibc 2.13, already installed on Ubuntu 11.10. So i need to find out a solution to install g++ without update glibc.

Answer 1

Simply, fetch a recent GCC 4.9 source tarball (and all the dependencies, perhaps using aptitude build-dep gcc or the contrib/download_prerequisites script inside GCC source tree) and compile it and install it from its source code (using your installed glibc-2.13...). You need to configure it (perhaps passing something like --program-suffix=-4.9-mine and possibly some --prefix) and build it outside of its source tree then install it. (then use g++-4.9-mine as your C++ compiler). Read and follow carefully the installation instructions
Running gcc -v will show you how your system GCC was configured.
BTW I am not sure that the version of glibc always matter that much (it really depends of a lot of factors). Did you try to compile your project (on whatever Linux system you have) and run it on a machine (perhaps a virtual one) with glibc 2.13? It might work (but I am not sure at all)!

Answer 2

You can obtain special version from Ubuntu toolchain ppa repo:
#cat /etc/apt/sources.list.d/ubuntu-toolchain-r-test-precise.list
deb http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu precise main
deb-src http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu precise main
Gcc 4.9
Pre build steps:
apt-get build-dep -y gcc-4.9-multilib
apt-get source -y gcc-4.9-multilib
dpkg-source -x gcc-4.9_4.9.2-0ubuntu1~12.04.dsc
cd gcc-4.9-4.9.2
customized parameters:
mkdir -p src && tar -xf gcc-*.tar.xz -C src
cd src && ./contrib/download_prerequisites && cd ..
mkdir -p /opt/dev-tools-4.9
../src/configure --prefix=//opt/dev-tools-4.9 \
-v --with-pkgversion='Ubuntu/Linaro 4.9.2-0ubuntu1~12.04' \
--program-suffix=-4.9 --enable-shared --enable-linker-build-id --with-system-zlib \
--libexecdir=//opt/dev-tools-4.9/lib --without-included-gettext \
--enable-threads=posix --with-gxx-include-dir=//opt/dev-tools-4.9/include/c++/4.9 \
--libdir=//opt/dev-tools-4.9/lib --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes \
--enable-gnu-unique-object --enable-plugin --enable-objc-gc --disable-werror \
--with-arch-32=i686 --with-abi=m64 --with-multilib-list=m32,m64 --with-tune=generic \
--enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu --with-sysroot=/ --enable-nls
make -j $(grep -c ^processor /proc/cpuinfo ) && make install
Also you should rebuild the binutils:
binutils 2.22
apt-get build-dep -y binutils-dev
apt-get source -y binutils-dev
dpkg-source -x binutils_2.22-6ubuntu1.3.dsc
mkdir objdir&& cd objdir
../binutils-2.22/configure --prefix=/opt/rdwr_tools/radware-dev-tools-4.9 \
--exec-prefix=/opt/rdwr_tools/radware-dev-tools-4.9 \
--with-sysroot=/ --enable-multilib \
--with-lib-path=/opt/rdwr_tools/radware-dev-tools-4.9/lib \
--disable-werror --enable-shared \
--enable-targets=x86_64-linux-gnu,i686-linux-gnu,x86_64-pc-mingw32,i686-pc-mingw32
make -j 8 && make install
