Hi, I have used/installed lime before but I have a new computer and am getting some compilation errors:

clang: warning: optimization flag '-falign-loops=16' is not supported [-Wignored-optimization-argument]
clang: error: unsupported option '-fopenmp'
make: *** [src/aux.o] Error 1

I don't want to go changing things in the make file... any ideas on a fix?

Thanks, Alice

I think you might need to just install a better compiler (i.e. one that includes openmp support - the standard OSX compiler does not). I have installed gcc via macports, and then I change the following line in the LIME Makefile:

CC = /opt/local/bin/gcc-mp-8 -fopenmp
