The autogen.sh script was introduced in version 3.0 because we decided that svn should no longer store the files generated by autotools. As a result, it makes sense for us to document the requirements for building TORQUE from source, as many in the community will desire to checkout the code and build it. Required packages: NOTE: running autogen.sh is only required for building from svn source. If you downloaded a distribution, either during the beta or the official release, this is not necessary. For running autogen.sh: autoconf automake libtool pkg-config Non-standard packages required for building the source: libssl-dev (name may vary among OSes) *** For admins that use cpusets in any form *** hwloc version 1.1 or greater is now required for building TORQUE with cpusets, as pbs_mom now uses the hwloc API to create the cpusets instead of creating them manually.
