[Build Issue]: Compiling fails with "error: unknown type name 'uint32_t'"

Describe the build issue

If compiling with Crashpad, building will fail with error: unknown type name 'uint32_t'. Neither build type nor generator seems to affect where it errors.

If compiling without Crashpad, building will fail with similar errors, like 'uint32_t' has not been declared and 'uint32_t' does not name a type. It errors in a different location than it would with Crashpad, but build type and generator doesn't seem to affect this location.

Relevant log output

With Crashpad:

Mind trying the suggestion outlined in ^? :)

[bluebandit21]

You're using a more modern GCC version (13) than our CI does (8,9,10), so quite possible we're doing something wrong that wasn't triggered before and is now.

I sillily ignored the note because I assumed there was some sort of issue on my end. (oops).

After adding #include <cstdint> to the problematic files, it now compiles perfectly!
I am getting issues with insane input latency (~50ms) that didn't seem to exist on the release binary, but I'll try to figure that out myself.

Edit: performance issues disappeared after reinstalling pipewire

[bluebandit21]

Interesting, might mean that change should be made as a PR too :)

I'm actually going to re-open the issue until ^ is worked out.

RE: performance problems, you're probably building a debug build (the default) instead of a release one. If your goal is playing the game, not writing code for it, that's likely your fix.

[poco0317]

just added a workflow for clang 16 and g++ 13 and it worked fine. reopen if reproducible problem arises

[bluebandit21]

Someone else encountered this just now, so should probably be reopened and fixed properly :)

having the same issue right now on fedora even when I tried the including cstdint
