provide arm64 compiled version of gen_snapshot_linux_x64_release tool

[moham96]

Hello,

Is it possible to provide an arm64 version of gen_snapshot_linux_x64_release? I have an arm64 laptop and want to generate the app.so on it instead of firing up my desktop PC.

Regards

Hey, theoretically that's possible but not sure I have a beefy enough ARM64 machine for that.
Github CI doesn't provide one at least and could be it takes ages to build on pi 4.

For now you'll have to use qemu-user-static I'm afraid.

Is the source code of the tool available ? so we can try to compile it ourselves

gen_snapshot is built as part of the flutter engine build.

For instructions see:

on second thought, doesn't GitHub ci support cross-compiling?

of course, it's just a linux machine (you can do everything you can do on your home computer as well), but I am already cross-compiling it: the gen_snapshot that generates snapshots for armv7 on a x64 linux machine is a side-product of cross-compiling the engine for armv7.

If you want to gen_snapshot itself to run on arm64 now you're basically cross-cross-compiling, which is not supported by the flutter build. Might be possible with some hacking but that'll probably break all the time.
