Module fails to compile on windows if the file doesn't have a ".exe" extension

[shawnafang]

when running the example_of_use, if using the

mp <- sampleStanModel(
    jm,
    data = stan_data,
    iter_sampling = 1000,
    iter_warmup = 1000,
    chains = 1,
    parallel_chains = 1,
    exe_file = file.path("local","full")
)

It failed with error:

Error in `process_initialize(self, private, command, args, stdin, stdout, ...`:
! Native call to `processx_exec` failed
Caused by error in `chain_call(c_processx_exec, command, c(command, args), pty, pty_options, ...`:
! Command 'C:/Users/fangx22/Documents/GitHub/jmpost/local/full' not found @win/processx.c:982 (processx_exec)

While replacing the exe_file = file.path("local","full") with exe_file=file.path() ， it works

might need help to figure out why path of "local/full' does not work.

I think this issue is because the "local" directory doesn't exist on your computer so its probably erroring rather than creating it, will add some code to create the directory if it doesn't already exist.

@shawnafang , I've updated the function to create missing directories. That being said re-reading your message I am wondering if the issue is that its missing the exe extension...

Would you mind re-running the example of use as is to see if it re-creates the error ? If it does would you mind changing the argument to exe_file = file.path("local", "full.exe") and seeing if that fixes it ?

The current version using exe_file = file.path("local", "full") still creat the same error, but exe_file = file.path("local", "full.exe") do fix it.

Ok ya so its a file extension issue with windows expecting .exe hmm ok. Does it work or do you get an error if you omit the argument (i.e. just delete the exe_file = ... line) ?

[shawnafang]

From the screenshot, you can see you have to give exe_file =NULL to make it work, otherwise it will report the error of "argument missing with no default"

O no sorry, I mean delete the entire line not just leave the argument blank, as in:

sampleStanModel(
  jm,
  data = jdat,
  iter_sampling = 1000,
  iter_warmup = 1000,
  chains = 1,
  parallel_chains = 1
)

Yes, I have tried. If so, it will show the error of "argument missing with no default"
