ARM64 laptops probably start getting its hand on like 2021 or 2022 (wild guess). As one of LÖVE development team, this makes me wonder if I can run LÖVE under Windows 10 ARM64, natively, because using x86 emulation is cheating and doesn't work anyway due to LÖVE dependency to OpenGL.
First thing I have to think is:
- Get Windows 10 ARM64 toolchain. This is easy. Visual Studio Installer provide this.
- Get QEMU.
- Get Windows 10 ARM64 image.
Fact: I have to go to my friend house and ask to use his WiFi to download those because I'm poor.
Quick testing the ARM64 toolchain by compiling my infamous HonokaMiku with CMake shows the ARM64 cross compiler works. Now before compiling LÖVE, these things comes to mind prior trying to compile it:
- LuaJIT doesn't support Windows/ARM64 combination.
- OpenGL is not supported.
Point 1 is kinda bummer because even LuaJIT interpreter is waaaayyy faster than Lua 5.1.5, but I have no choice other than adding -DLOVE_JIT=0 CMake flags later on. Point 2 can be solved by using ANGLE. I have to "brute-force" GitHub Actions to get ANGLE compiled for ARM64, but this pays off and the actions build script can be extended to other architecture later as well.
When trying to compiling it, unfortunately SDL, PhysFS, Vorbis, and OpenAL-soft fails to compile. I've filled issue tracker for OpenAL-soft but SDL (and others) probably needs to wait longer as I also need to attend online classes (univ related), thus slowing down this experiment as whole. Known libs to compile are FreeType, GLSLang, zlib, and Ogg. Others are unknown as MSBuild prevents me compiling other dependencies.
For the VM part, I haven't getting myself a way to pass OOBE in Windows 10 ARM64 running under QEMU. Mind you, it's slower than dirt in i5-7200U. Blogpost about setting up the VM need to wait.
Also this is me trying to get LÖVE compile with Windows 10 ARM64 toolchain:
