Install milc

Forked, cloned. I need to modify the makefile. It works by copying a Makefile into the directory of the application you'd like to build, then running make [a target from Makefile_template].

...off to a good start.

• make ks_spectrum_hisq:

../generic_ks/io_helpers_ks_eigen.c:82:23: error: static declaration of ‘w_open_ks_eigen’ follows non-static declaration

I've tried almost all the options in Makefile_template, it looks like this is normal. OK, I need to see why it's redefined, but I suspect it's just a bug. Yep, it's a GCC 3 vs GCC 4 bug, GCC 4 is stricter on this.

Raised an issue: https://github.com/milc-qcd/milc_qcd/issues

Running the tests: make check "EXEC=ks_spectrum_hisq" &> make_test.log

The process terminates with:

make[1]: *** No rule to make target 'ks_spectrum_hisq.periodic.2.corrfile_t0.test-diff'.  Stop.

Along the way, I get the following errors:

Making ks_spectrum_hisq.fpi.1.test-diff with patterns PLAQ: NERSC

This repeats for every test case:

Then again for double precision. What's in those output files?
Aha. The .sample-tmp files are empty, because the .tes-out files have the error:

get_i: ERROR IN INPUT: expected max_cg_iterations but found set_type

Figured out the error, here: milc-qcd#66

OK, enough tests pass that I'm fairly confident I've installed it OK and it works.
