Operating System: x86_64-w64-mingw32/x64 (64-bit), Windows 10 x64 (build 17134)
Interface Version: cmdstanr_0.0.0.9000
Compiler/Toolkit: Rtools 3.5
I am trying to compile a model with cmdstanr and am getting the error
mingw32-make.exe: *** No rule to make target ‘C:/Users/gubi/[…]/sim/test.exe’. Stop.
Error in processx::run(command = make_cmd(), args = c(exe, include_paths), :
System command error
I can compile the same model with Rstan, so the model should be OK.
Looking through other posts here on discourse suggest that the make flags could be the problem, but I didn’t manage to set the make flags for cmdstanr successfully.
My Makevars.win file, which I think is used by Rstan but not cmdstanr, has the following content:
CXX14FLAGS=-O3 -mtune=native -Wno-unused-variable -Wno-unused-function -fPIC
CXX14 = $(BINPREF)g++ -m$(WIN) -std=c++1y
Does the solution to my problem involve submitting these flage to cmdstanr?
I tried by putting the lines into quotes and submitting them as an argument to
compiler_flags, but this did not work.
Any hint/help is appreciated.
a few question to understand the issue a bit better:
- are you able to compile any other models on this system or is this a specific model problem?
- does the model include other files or anything like that?
- does the path to the model or the path to cmdstan have any spaces in them?
Looking at your flags quickly I dont see any flag that would be the reason behind this.
- I cannot compile any other model with cmdstanr (I tried the example from cmdstanr’s Getting started to be sure)
- the model does not include other files or anything like that
- the path has spaces (not my choice …) but temporarily moving the stan file to a location without spaces in the path does not result in successful compilation.
PS: I could previously use cmdstanr on the system, so I really don’t understand why it does not work anymore. I can also check with the local IT department and ask if they have changed rights/permissions.
Is it possible that you moved the location of cmdstan and did not update the cmdstan path?
Maybe try running set_cmdstan_path() anyways https://mc-stan.org/cmdstanr/reference/set_cmdstan_path.html
Otherwise you could go in the cmdstan folder, open the windows command line and try running:
The path should not include spaces in this case. This is a limitation of the make system so spaces in path are an issue for Cmdstan also but can be circumvented in cmdstanr. We will address this issue shortly.
It turns out the spaces were the problem.
Thanks for your help!
