 +===== 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.
 +
 +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.
 +
 +<code>
 +$ module --terse avail |grep gcc
 +/etc/environment-modules/modules:
 +gcc/4.9.4
 +gcc/5.5.0
 +gcc/6.5.0
 +gcc/7.5.0
 +gcc/8.4.0
 +gcc/9.3.0
 +gcc/10.2.0
 +
 +
 +$ module load gcc/4.9.4
 +
 +$ echo "$PATH | $INCLUDE | $LD_LIBRARY_PATH | $MANPATH"
 +/usr/local/gcc/4.9.4/bin:/home/kauffman3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/opt/puppetlabs/bin 
 +| /usr/local/gcc/4.9.4/include | /usr/local/gcc/4.9.4/lib | 
 +/usr/local/gcc/4.9.4/man:/usr/share/man
 +
 +$ gcc --version
 +gcc (GCC) 4.9.4

 +$ module unload gcc

-If building a package you will want to use `checkinstall`. Replace `make install` something like the following:+===== Troubleshooting ===== 
 +==== 'module' command not found ==== 
 +To resolve you may have to do the following:
 <code> <code>
-checkinstall \ +source /etc/profile.d/modules.sh
-  --strip=no \ +
-  --stripso=no \ +
-  --umask=022 \ +
