That said taking this approach you need to cross compile the engine for aarch64.
Another approach is to simply run AGL Flutter aarch64 build on an M1 using QEMU.

Hi Bernard,I would suggest using UTM on the M1. I am using Ubuntu 20.04 on my M1 max via UTM. It's easy to set up and it worked the first try.Using Ubuntu 20.04 there is no deviation from the documentation on how to build, etc.JoelOn Sat, Jan 15, 2022 at 11:34 PM Bernard <bernard@xxxxxxxxxxxxxx> wrote:Giday Joel,We gave this a crack taking the road least traveled scenario 2, parallels running Wayland cross compile flutter-engine for host (arm64).My flutter dev running Mac/M1 gave up too many issues, If you get it working please share.So I had a go on my Mac/x86 and got as far asm/types.h file not found., and when searching my local I have multiple copies, so which to use and how to include./home/parallels/Android/Sdk/ndk/23.1.7779620/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include/linux/types.h:21:10: fatal error: 'asm/types.h' file not found

We're not embedded or even 'c' programmers so it's all a bit of a mystery, only as your time permits if you can advise which and how to include asm/types.h i'll give it another whirlAlso attached for our internal benefit steps taken doc and log flutter_embedded build steps Intel Mac Parallels Ubuntulastly just for good measure i repeated same on windows/x86 WSL2 and also got asm/types.h not foundthanks and regardsBernOn Fri, Nov 12, 2021 at 3:48 AM Joel Winarske <joel.winarske@xxxxxxxxx> wrote:Hi Bernard,Two scenarios:1. Run emulated x86_64 on arm64 via QEMU (Lamprey AGL emulator image, use cross compiled bits; deal with performance loss - maybe not bad if virtualgl passthrough works)2. In parallels environment that runs Wayland cross compile flutter-engine for host (arm64). Build ivi-homescreen to use this flutter-engine by overriding/setting variables during cmake invocation. This is supported today. The "ci" branch of https://github.com/jwinarske/flutter_embedded will help with building the flutter-engine.I might suggest focusing on scenario 1 as that has the least amount of variation. Only unknown is if/how-well virtualgl passthrough works - or not.That said, I'm expecting a new MBP M1X (64GB) in a few weeks, so I will be trying both myself at that time.Cheers,JoelOn Tue, Nov 9, 2021 at 8:01 AM Bernard <bernard@xxxxxxxxxxxxxx> wrote:Hello Joel and AGL members,
for our flutter dev we use Mac's as it's a mandatory requirement within Apple's walled garden of iOS apps. So for the Linux desktop we adopted Mac Parallels Ubuntu 20.04.2.I have Mac intel (x86_64) and was able to get Pumped Fuel working on Toyota IVI homescreen easily enough albeit looks kind of sketchy compared to standard linux desktop, needs beautifyingHowever my colleague, our flutter developer, who has a Mac M1 (arm) is blocked on the build. Can anyone help us out and advise what can be done to get this working on the M1.Hi Bernard,I was trying to build https://github.com/toyota-connected/ivi-homescreen on the Parallels ubuntu, where I've hit a roadblock.I was following the Readme steps. One thing I noticed was that the notes are for x86_64 architecture, but my ubuntu is arm64. I am not sure if that is the reason for the failure. While following GCC/libstdc++ Build in the Readme.md it failed in make install -j stepThe error thrown was/usr/bin/ld: ../libflutter_engine.so: error adding symbols: file in wrong format
collect2: error: ld returned 1 exit status
make[2]: *** [shell/CMakeFiles/homescreen.dir/build.make:596: shell/homescreen] Error 1
make[1]: *** [CMakeFiles/Makefile2:94: shell/CMakeFiles/homescreen.dir/all] Error 2
make: *** [Makefile:152: all] Error 2Seems like it is because of the architecture difference x86_64 vs ARM64. if possible can you confirm this from the writer (if you have contacts / access).Regards
