Can `yarpgen` run on MSVC? #193

Closed OfekShilon closed 11 months ago

OfekShilon commented 11 months ago

Unlike clang/gcc, MS's cl.exe is not a driver that can invoke the linker. Is there some test_sets.txt setting that can get generated programs to build?

that not true

CL automatically invokes the linker after compiling unless the /c option is used.

@LowLevelMahn thanks, didn't know this. Will close the issue.

and "yes" please, integrate MSVC into your testing - you will find many ICEs :)

this would definitely be interesting but I'm not sure any of us has the time to test this compiler right now (I don't even know if any of us has a Windows machine at all).

but I agree that we want yarpgen to work, for some reasonable value of work, on windows.

@regehr I made some changes on my fork towards the end of being able to run on windows - but the main obstacle is the use of multiprocessing. On linux a new process is forked, on windows it is spawned - and many globals that are initialized only in main do not survive the spawn. As far as I can see solving this would require some re-design.

You can imitate the problem on linux by calling multiprocessing.set_start_method("spawn") from main on linux too. Perhaps you have any idea how to support spawning? Perhaps yarpgen can be made to use threading instead of multiprocessing?

I think MSVC has a lot to gain from this tool, really hope this can be made possible.
