Debugging stanify on win / cmdstanpy issue

[tomfid]

I tracked the issue a little farther.

The error message arises in cmdstanpy\model.py around 563, due to an earlier failure of do_command around 530.

do_command is defined in cmdstanpy\utils\command.py, which launches a subprocess with:
cmd = ['mingw32-make', 'STANCFLAGS+=--include-paths=C:/bayes/git/stanify/vignette/stan_files/hier_preypredator', 'C:/bayes/git/stanify/vignette/stan_files/hier_preypredator/draws2data_hier_preypredator.exe']
cwd = 'C:\Users\tom\.cmdstan\cmdstan-2.31.0'

To test this I opened up a cmd prompt and ran the same thing manually:

c:\Users\tom.cmdstan>cd cmdstan-2.31.0

c:\Users\tom.cmdstan\cmdstan-2.31.0>mingw32-make STANCFLAGS+=--include-paths=C:/bayes/git/stanify/vignette/stan_files/hier_preypredator C:/bayes/git/stanify/vignette/stan_files/hier_preypredator/draws2data_hier_preypredator.exe

There seem to be multiple errors, so I'm not sure what's going on here. The weird thing is that it does end up with an .exe built, in spite of all the complaints.

[tomfid]

I think the 'cut' errors are a distraction - they seem to come from a piped command,
CXX_MAJOR := $(shell $(CXX) -dumpversion 2>&1 | cut -d'.' -f1)
The consequence of CXX_MAJOR being undefined is a couple flag changes and the error at 125.

It seems like the real issue is the attempt to rm -f the .o file. The file exists, so I don't know why the attempt to delete it fails.

@tomfid were you able to replicate the eyeball diagram in your computer?
