The core of this software stack is provided by the <code>nixpkgs/16.09</code> module, which is loaded by default. This | The core of this software stack is provided by the <code>nixpkgs/16.09</code> module, which is loaded by default. This stack, internally managed using the Nix package manager, is located at <code>/cvmfs/soft.computecanada.ca/nix/var/nix/profiles/16.09</code>. The environment variable <code>$EBROOTNIXPKGS</code> should be used to refer to this path. | ||
Under this location you can find all of the common packages typically included with Linux distributions, for instance <code>make</code>, <code>ls</code>, <code>cat</code>, <code>grep</code>, and so on. Typically, when you compile some software, the compiler and linker will automatically look for header files and libraries in the right location (via the environment variables <code>$CPATH</code> and <code>$LIBRARY_PATH</code>, respectively). | Under this location you can find all of the common packages typically included with Linux distributions, for instance <code>make</code>, <code>ls</code>, <code>cat</code>, <code>grep</code>, and so on.

Some software, however, has been | Some software, however, has been hard-coded to look under <code>/usr</code>. If that is the case, the compilation will typically fail, and needs to be explicitly told about <code>$EBROOTNIXPKGS</code>. Sometimes that means adjusting a Makefile, sometimes it needs to be specified in a certain <code>--with-</code> flag for the configure script, or a configuration file needs to be edited. If you are not sure how to do this please do not hesitate to ask for help. | ||
