This is yet another issue with implicit includes, precompiled headers, etc. rpcs3/Input/gui_pad_thread.cpp needs #include <unistd.h>.

[Tatsh]

Note that Clang 18 will not work but 17 does. Clang 18 actually crashes during compile. I do not know how to fix it though the crash is probably a concern for Clang upstream/Gentoo and not RPCS3.

[Tatsh]

Clang 18 bug was reported here https://github.com/llvm/llvm-project/issues/84634

[ThisNekoGuy]

Note that Clang 18 will not work but 17 does.

That's fine; I actually pinned all of the Clang17 and LLVM17 related things (masked everything below and above 17) because 17 was installed as an update one day a while back, alongside 16, and figuring out how to actually transition completely took me a while. eselect supports switching more easily between GCC versions but doesn't do so with LLVM, so manipulating masks was the best way I found to go about it. 18 is listed as stable anyway, and 17 mostly works fine for me, so I won't be updating to 18 for a long while (even when it becomes stable) anyway.

[ThisNekoGuy]

@Tatsh I wasn't able to rebuild back then (had to send my GPU out for an RMA), but I found that it still occurs with Clang/LLVM 17: emerge_rpcs3_build.log

Different error, but same version number (0.0.31)

[Tatsh]

Probably wolfssl compatibility. Please make a new issue.
