One of the key features of EasyBuild is that it automatically generates environment [[Utiliser_des_modules/en|modules]] which can be used to make a software package available in your session. In addition to defining standard Linux environment variables such as <tt>PATH</tt>, <tt>CPATH</tt> and <tt>LIBRARY_PATH</tt>, EasyBuild also defines some environment variables specific to EasyBuild, two of which may be particularly interesting to users: | |||
* <tt>EBROOT<name></tt>: Contains the full path to the location where the software <tt><name></tt> is installed. | |||
* <tt>EBVERSION<name></tt>: Contains the full version of the software <tt><name></tt> loaded by this module. | |||
For example, the module <tt>python/3.10.2</tt> on Narval defines: | |||
* <tt>EBROOTPYTHON</tt>: <tt>/cvmfs/soft.computecanada.ca/easybuild/software/2020/avx2/Core/python/3.10.2</tt> | |||
* <tt>EBVERSIONPYTHON</tt>: <tt>3.10.2</tt> | |||
< | = Installation recipes and logs = | ||
... | EasyBuild keeps a copy of the recipe used to install each software package, as well as a detailed log inside of the installation directory. This is accessible in the directory <tt>$EBROOT<name>/easybuild</tt>. For example, for the <tt>python/3.10.2</tt> module, the installation directory contains, amongst other things: | ||
* <tt>$EBROOTPYTHON/easybuild/Python-3.10.2.eb</tt> | |||
* <tt>$EBROOTPYTHON/easybuild/easybuild-Python-3.10.2-*.log</tt> | |||
