Dear Jan, dear others, Greetings from MSYS! I think I have a few minor path issues, and maybe you could give me a bit of guidance. After installation, I get errors in test\_xpce, saying that use\_module(library(pce)) fails. I can work around this by the steps below, basically loading swipl-win.rc. Note that I don’t seem to have swipl.rc. I guess swipl.rc and swipl-win.rc belong to swipl.exe and swipl-win.exe, respectively, but swipl-win.exe is actually disabled during cmake. So I end up with swipl.exe and swipl-win.rc, which is probably not indended. Is my conclusion correct?

So I end up with swipl.exe and swipl-win.rc, which is probably not indended. swipl-win.exe comes from two places. From `packages/swipl-win` we get a version based on the portable Qt framework. On Windows we get `swipl-win.exe` from the main source (inplemented by `src/win32/console`). That should still be there, no? An executable loads the `.rc` file based on the name of the binary. Historically, the console application could not support graphics and the whole purpose of `swipl-win.rc` is to link xpce into Prolog. This has changed, notably because xpce now by default runs in its own thread and therefore we no longer have to combine the Windows message loop and console input in one thread. You can try using ```prolog swipl.exe ?- [swi('swipl-win.rc')]. ?- emacs. ``` On the normal Windows binary this seems to work (only tested some basics). We could consider installing `swipl.rc` along with `swipl-win.rc` (they should be the same). It might give some issues for people creating saved states from `swipl.exe` as these have the tendency to include xpce unless started using `swipl --no-pce` or `swipl -F none` to stop loading the init file. ---

```prolog swipl.exe ?- [swi('swipl-win.rc')]. ?- emacs. ``` Yes, works here as well (under MSYS2). Nice! > [@jan](#): > > It might give some issues for people creating saved states from `swipl.exe` as these have the tendency to include xpce unless started using `swipl --no-pce` or `swipl -F none` to stop loading the init file. Yes—on the other hand, wouldn’t it be my own responsibility whether to install swipl with xpce support or not? I may not get the problem here, and what I am actually trying is do is only to get “test\_installation” running on MSYS2. ---

The packager typically decides on that 🙂 > [@mgondan1](#): > > what I am actually trying is do is only to get “test\_installation” running on MSYS2. That can also be done using this around ```prolog :- if(exists_source(library(pce))). ``` Pushed a fix this way. That still allows for installing `swipl.rc`, but prevents the test from failing if the test executable does not have xpce enabled. ---
