Thank you! This helped me get further along and it seems like it is close to compiling, but I still run into errors which I think might be with the make.common file.

These are the last lines I get when I try to compile.

&& cp exciting ../../bin/excitingser
……………………..
AMBIGUOUS: Module xc_f90_ is associated with ../../src/libXC/src/libxc.f90 as well as ../../src/libXC/src/libxc.f90.
make[2]: * [bin] Error 255
make[1]: * [all] Error 2
make: *** [serial] Error 2

This is after also replacing the
LIBXCMOD= ../../src/libXC/src/libxc.f90 ../../src/libXC/src/libxc_funcs.f90

line with
LIBXCMOD= ../../src/libXC/src/libxc.f90

I don't know if the library is getting inserted again automatically. The Perl script build/utilities/mkmf might be putting the 2 copies of the library in build/make.common, but when I looked at the make.common file it did not appear to be reverted.

Is there a way I can modify the mkmf script so it only puts a single copy of ../../src/libXC/src/libxc.f90 in make.common? Has Exciting ever been built on OSX?

Now I also have this error and I have no idea why. Are there other make files I need to modify?

checking for Fortran flag to compile .f90 files… unknown

Hi Michael,

I've just successfully compiled exciting on my Mac laptop.
I've used MacPort packages (I guess you do so):
gcc-mp-4.8
cpp-mp-4.8
gfortran-mp-4.8

Then, just for simplicity, rerun
perl setup.sh
and select platform 6 gfortran.

Please add/replace the corresponding lines in build/make.inc

FCC = gcc-mp-4.8
CPP = cpp-mp-4.8
FCCPP = cpp-mp-4.8
F90 = gfortran-mp-4.8
F77 = $(F90)
F90_OPTS = -O3 -fopenmp -DUSEOMP -ffree-line-length-0
…

Check it out!

Thank you for your suggestion. I added those lines.

However, I'm not so familiar with MacPorts, but I did install it and ran 'port install gcc48', but I'm not sure about how to obtain the other packages or where they would go. I was just trying to following the tutorial here on how to install and compile. Would you mind elaborating what you mean by using the various MacPort packages and what steps one needs to take?

I think I have the gcc and gfortran, but maybe not the cpp. After running make clean and then make again, I think I got past the errors I mentioned, but now I'm getting a new error relating to mod_muffin_tin.o, which I'm not sure about. Does anyone have an idea what to do? This was the error message:
