Help: AssertionError: Target does not exist. about pymake

Would need more information from you. Are you running on a Mac? Do you have gfortran installed?

[langevin-usgs]

The mf2005 unix distribution (the one that is downloaded when you run the make_mf2005.py script) comes with a make file. Can you open a terminal window in the make folder and type "make". It should compile with gfortran. If this doesn't work, then I suspect gfortran is not configured correctly on your mac. I install gfortran on my mac using Macports, but I'm sure there are other ways to get it installed properly.

Yes, I am on Mac version 10.12.5 and I'm not quite sure if gfortran is installed, here is what happens when I enter 'gfortran --version' in the terminal:
gfortran: warning: couldn’t understand kern.osversion ‘16.6.0

Awesome, after updating xcode, gfortran and the "make" command seems to have worked. There's still a bunch of warnings (ld: warning: object file (./obj_temp/mf2005.o) was built for newer OSX version (10.12) than being linked (10.4)), could this be something wrong with the makefile, or with gfortran not being installed/updated correctly? I changed the compile flags in the makefile before as directed by https://adamsgaard.dk/files/MODFLOW-OSX-Installation-Guide.pdf

Thanks so much for the help and the quick response!
