If anyone has any comments about the package, please let me know!

Hello! I noticed that this package has switched to GCC. May I ask why was that done? Just to make it clear, I am not opposing this change.

It's because before I had urged you to switch to GCC but you had said the compile times should be better with Clang.

I am guessing it's because something like performance or compile times improved in GCC 16?

Hey, the prepare() is now redundant, see: https://github.com/azahar-emu/azahar/commit/254ab96b63d8c7bb0b22516b3c0a01968f1e115c Please remove it. Thanks!

Hello. I noticed that your package generates a "tests" binary but never uses it, or disables it. Please use it using a check function, or turn it's compilation off. Thanks. You can see azahar-git package for an example of how they implemented it.

I did some benchmarks for lld and mold with the same PKGBUILD. And mold was only 5 seconds faster. I guess it doesn't really matter which linker to use in this case. It's purely your call.

@HurricanePootis

But if Clang is used for compiling then Mold should automatically use the LTO plugin provided by clang, right? Which means it should improve the raw linking time, if not the LTO time.

@LinuxLover471

I'm not using Mold because Mold just uses GCC's lto plugin for linking, thus keeping the same link times. Furthermore, Clang + lld is usually faster forst most people out there.

I can replicate sim590's error message:

/home/username/.cache/yay/azahar/src/azahar-unified-source-2123.3/src/citra_qt/bootmanager.cpp:42:10: fatal error: 'qpa/qplatformnativeinterface.h' file not found 42 | #include <qpa/qplatformnativeinterface.h> | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated.

I can verify I have the header on my system: find /usr/include -name qplatformnativeinterface.h /usr/include/qt6/QtGui/6.10.0/QtGui/qpa/qplatformnativeinterface.h /usr/include/qt/QtGui/5.15.17/QtGui/qpa/qplatformnativeinterface.h

Compiling against qt6-base 6.10.0 now yields this error message:

To circumvent this error, I had to make symlink like so:

/usr/include/qt6/QtGui/qpa -> /usr/include/qt6/QtGui/6.10.0/QtGui/qpa

I'm not sure where the problem is. I don't think that -DCMAKE_INCLUDE_PATH should have the qt package version as an argument. I don't know what to suggest to fix that.

Hey, I hope that you are doing fine.

I wanted to ask why is the build using clang, and lld? For my PC (Which is very old and weak), gcc actually compiles faster (approx 7mins) with Full LTO than clang with Full LTO (Only clang supports thin-lto, but I doubt thin lto will make a difference, as gcc already compiles faster in Full LTO). As much as I know, upstream doesn't recommend either compiler.

As for the linker, I recommend using mold. Mold is very reliable (I use it as a daily driver) and faster than lld. I have compiled azahar multiple times with mold.

You can keep clang, (although I urge to use gcc by default) I would HIGHLY recommend to use mold, thanks.
