Crashing with UWP Xbox

[3UR]

I am porting a game to UWP for Xbox and I came across this issue with OpenAL do I need to change code on my side? or is this an issue with OpenAL library?

I am using VCPkg and the triplet I use is x64-uwp

Info

File: core/helpers.cpp
Line: 105

This is how I initialize OpenAL

Exception

Exception thrown: read access violation.
*****(__imp___p___wargv(...)) was nullptr.

Hm maybe this is why?

for some reason that if check is not actually doing anything 🤔

Guess I could define it in my project and see what happens

[3UR]

Nope :( Defined it in my project and it still happens

Line 362 would be this:

path = fs::u8path(GetProcBinary().path);

It's that GetProcBinary() call, which tries to read __wargv[0] to get the executable path and name of the process on UWP. On non-UWP Windows, it uses GetModuleFileNameW(nullptr, ...) instead, but that's apparently not available on UWP. If __wargv can also be a null pointer, that may need checking.

Is there anything that can be done on my end to workaround this?

Not unless you can figure out why __wargv may be null and can fix it. Otherwise you'll need to build OpenAL Soft from source and make sure to include commit c14554f (either patching 1.24.2 with it manually, or using the latest Git version).

Thanks I'll give the commit a try
