We can haz GCC
GCC Versions that are already installed on CS infrastructure
Usually, we install multiple versions. The default version of GCC probably won't be changed system wide… ever.
Here is a list of packages we install as of 2017-05-02:
gcc gcc-4.7-uofc-cs gcc-4.9-uofc-cs gcc-5 gcc-5-base:amd64 gcc-5-multilib gcc-5.4-uofc-cs gcc-6-base:amd64 gcc-6-base:i386 gcc-6.3-uofc-cs gcc-7.1-uofc-cs
We are now taking more advantage of environment modules. This means depending on when you read this you could load the version of GCC you want to use.
kauffman3@green:~$ $ module --terse avail /etc/environment-modules/modules: cmake/3.1.1 cmake/3.8.0 gcc/4.7.4 gcc/4.9.3 gcc/5.4.0 gcc/6.3.0 gcc/7.1.0 kauffman3@green:~$ module load gcc/4.7.4 kauffman3@green:~$ echo "$PATH | $INCLUDE | $LD_LIBRARY_PATH | $MANPATH" /usr/local/gcc/4.7.4/bin:/home/kauffman3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/opt/puppetlabs/bin | /usr/local/gcc/4.7.4/include | /usr/local/gcc/4.7.4/lib | /usr/local/gcc/4.7.4/man:/usr/share/man kauffman3@green:~$ gcc --version gcc (GCC) 4.7.4 kauffman3@green:~$ module unload gcc/4.7.4 kauffman3@green:~$ gcc --version gcc (Ubuntu 4.9.4-2ubuntu1~14.04.1) 4.9.4
Building GCC in your home directory
https://gcc.gnu.org/wiki/InstallingGCC
You will want to prepare a sandwich and a drink once we start compiling.
Requirements
- About 6.5G of scratch space.
- ~1G for the actual install. This means if you require a higher quota you will need to request this before proceeding.
You will want to use /var/tmp, /tmp, or /local as the place to checkout and build GCC.
Example
#!/bin/bash PREFIX="$HOME/.local/gcc/4.9.3" # Building gcc in $HOME INSTALLDIR=/tmp/$USER mkdir -p $INSTALLDIR cd $INSTALLDIR svn co svn://gcc.gnu.org/svn/gcc/tags/gcc_4_9_3_release gcc-4.9.3 cd gcc-4.9.3 ./contrib/download_prerequisites cd ../ mkdir objdir cd objdir $PWD/../gcc-4.9.3/configure \ --prefix=$PREFIX \ --enable-languages=c,c++,fortran,go \ --enable-shared \ --enable-multiarch \ --enable-threads=posix make -j4 make install # clean up rm -r $INSTALLDIR/objdir export PATH=$HOME/$PREFIX/bin:$PATH export LD_LIBRARY_PATH=$HOME/$PREFIX/lib:$LD_LIBRARY_PATH echo "You should add the following to your .bashrc" echo "to make the exports permanent" echo " export PATH=\$HOME/$PREFIX/bin:\$PATH" echo " export LD_LIBRARY_PATH=\$HOME/$PREFIX/lib:\$LD_LIBRARY_PATH"
