Doxygen is a tool for building documentation for source code e.g. inter-related HTML pages for C++ source code.
Doxygen can be loaded with either:
module load apps/doxygen/1.8.13/gcc-4.9.4 module load apps/doxygen/1.9.1/gcc-8.2-cmake-3.17.1
NB Doxygen has a run-time dependency on
libstdc++ so the above also needs to
(and does) load the GCC compiler version 4.9.4 or 8.2 respectively.
