ALCOREM v0.1.x =========== Topics in this troubleshooting: - **OSX problems when compiling** --- ### OSX problems when compiling If you experienced a problem with OSX when compiling this code, one of the possible issue is related to this error: "clang: error: unsupported option '-fopenmp' clang: error: unsupported option '-fopenmp' make: *** [compute_complexity] Error 1" This issue is related to a clash between clang and openmpi. A possible workaround is through brew, updating gcc: ``` brew install gcc ``` If you then compile the code with the makefile using `gcc-8` instead of `gcc`, it should work. Just modify the Makefile as: ``` "CC=gcc" -> "CC=gcc-8" ``` If the previous workaround does not work, then try to compile the code in a different way. Remove the option "-fopenmp" inside the Makefile, then modify the environment variable CC in this way: ``` "CC=gcc" -> "CC=clang -Xpreprocessor -fopenmp -I/usr/local/include -L/usr/local/lib -lomp" ```
