[Bug]: Qt6 Unknown CMake command "qt6_android_apply_arch_suffix"

[DuilioPerez]

Problem description

Hello, I'm trying to port a KDE's game for Termux, and I've compiled some KF6 modules that aren't in the Termux's repos. But when I try to compile kf6-kiconthemes cmake can't find that macro. Acording to Qt documentation, "qt6_android_apply_arch_suffix" was introduced in Qt 6 link here. But when I try to compile I have the next error:

The actual issue in qt6 can be fixed. Also, how many packages do you need for that KDE game? I could try to add those packages after asking permission to do so.

The actual issue in qt6 can be fixed. Also, how many packages do you need for that KDE game? I could try to add those packages after asking permission to do so.

I need the following packages: kf6-kcolorscheme kf6-kconfigwidgets kf6-kcrash kf6-kdbusaddons kf6-kiconthemes kf6-kxmlgui kf6-doctools kf6-newstuff. I've compiled most of them. I've not compiled kf6-kxmlgui, wich depends on kf6-kiconthemes, kf6-doctools and kf6-knewstuff, these I've not tried to compile. The others compile successfully. kf6-kcrash and kf6-kdbrusaddons need to be compiled with KF_IGNORE_PLATFORM_CHECK variable set to true because Android isn't supported. Also all those packages need the following configuration in cmake -DQT_REQUIRE_HOST_PATH_CHECK=NO -DQt6HostInfo_DIR=/data/data/com.termux/files/usr/lib/cmake/Qt6HostInfo/. It was confusing to me because I'm not familiar with Qt and KDE, but it seems it try cross compilation everytime, so this is needed

[Biswa96]

For quick workaround, you could try to comment out the following line in $PREFIX/lib/cmake/Qt6Core/Qt6CoreMacros.cmake file.

After doing that: It happens the same error, even deleting the cmake build cache directory:

Does adding -DCMAKE_SYSTEM_NAME=Linux option with cmake make any change? Also, the host info option is not required when compiling in same Android system.

[DuilioPerez]

Ok, it seems it worked. But it requires breeze icons. The problem is, I can't compile it because it crashes termux.

[DuilioPerez]

I'll try to compile the others two modules and then I'll see how to compile this one. It's just breeze icons the problem.

[DuilioPerez]

@Biswa96 Almost all done! Just need two modules that I can't compile, kf6-kdoctools and kf6-kxmlgui, the last depends of kf6-kiconthemes and this depends on breeze-icons

[Biswa96]

Could this issue be closed now? IIUC, there is nothing actionable in this repository.

[DuilioPerez]

Yes, closing now
