May just be a simple dir creation issue. install.sh fails at the Doxygen stage rexgen v2.0.8 The system is: Ubuntu 16.04.4, kernel is Linux - 4.4.0-87-generic - x86_64 When I run install.sh mypc:~/localpacks/src/rexgen$./install.sh output is

I haven't tested beyond successfully running ./install.sh but I solved the upfront issue. Added ./rexgen/docs/DoxyFile.in which I generated with $doxygen -g The only mods I made to the default DoxyFile was to add the ".in" file extension (as that is how it is written in rexgen/src/cmake/doxygen.cmake and it wouldn't recgnize the plain DoxyFile name) and I changed from default NO to YES on the line OPTIMIZE_OUTPUT_FOR_C = YES though I also had success with it set to NO. NO is intended for C++.
