Arch Linux User Repository

Fixed the bug.

@docquantum, also your SDL3 build issue is something I do not experience, not on my desktop, laptop, or in a clean chroot environment. If you're using Manjaro, this is the arch user repository, not the manjaro user repository.

@docquantum Whenever you typed -DCMAKE_CXX_FLAGS="-DNDEBUG", you basically made Cmake only use that as the user-provided CXXFLAG and ignored everything in /etc/makepkg.conf. If this is fixing the bug for you, then the problem is most likely within the standard arch build flags. I will look into it.

Also, not sure if the package needs to be changed to facilitate the fix for this bug: https://github.com/minecraft-linux/mcpelauncher-manifest/issues/1079

Or if I'm doing something wrong, but the suggestion is to add -DNDEBUG as a build arg to prevent the "Please check your Keyboard Layout. No Fallback Implemented" window from popping up whenever clicking on non-game keys (e.g. super)

I'm not sure if this is the right place for it since there is a "debug" binary that is created that would ideally not be built with this flag.

I wasn't able to get this to build on Linux 6.13.1 because of SDL3 failing to build due to not being able to find linux/blkdev.h as part of the uring submodule. This might be a missing import since I have linux-headers installed and everything needed for the file to exist.

Not sure if that's related to the packaging or the actual repo.

I was able to get around it by adding -DSDL_LIBURING=OFF to the _args in the build() function:

@HurricanePootis Thank you very much for your kind words and for your work on this package!

@asalde_le1

Don't be sorry that you asked questions. Asking questions is the best way to learn. Sorry if I came across rude. You did a good thing reaching out to me with your concerns, even if in the end they ended up being not true. Without you, I wouldn't have gone again and checked the flags to get it building. So, thank you for motivating me to do a deeper check!

@HurricanePootis thank you for the detailed answer. Sorry if some of my questions were dumb.

1. Setting DCMAKE_BUILD_TYPE to Release is not advised by the CMake package guidelines, as it overrides the makeflags set for Arch Linux
2. The reason why you thinking specifying -stdlib=c++17 fixed the issue is because by giving cmake the arugment -DCMAKE_CXX_FLAGS="-stdlib=c++17", you are not passing along the $CXXFLAGS variable to Cmake as defined in /etc/makepkg.conf, where the -Wp,-D_FORTIFY_SOURCE-3 is. The project currently builds and is able to run as is. If the project requires C++17, then it will be automatically set in Cmake as needed by the developers. Edit: mcpelauncher-manifest's CMakeLists.txt does set C++17 as a standard, no need for the flag.
3. If you would to read the PKGBUILD, -DENABLE_DEV_PATHS=OFF is already set

Also please add -DENABLE_DEV_PATHS=OFF option and change DCMAKE_BUILD_TYPE to Release. And the v1.0.0-qt6 version is released
