Loading

The library loading problem is still an issue. Output of running flutter_glfw:
/flutter_glfw: error while loading shared libraries: libflutter_engine.so: cannot open shared object file: No such file or directory
The libflutter_engine.so is in usr/lib/arm-linux-gnueabihf/libflutter_engine.so. The executable tries to load it, but it is unsuccessful.

@ranciere not yet. Just finished setting up my new build machine. Soon

I've also bought a new machine (Ryzen 9 3900X) because of the compilation time :D

It should look something like this

If you change Flutter Channel to 'beta', it works

difference in one section

Okk, try run
readelf -A ./libstable.so
<empty result>

readelf -A ./libbeta.so

Attribute Section: aeabi
File Attributes
  Tag_CPU_name: "6"
  Tag_CPU_arch: v6
  Tag_ARM_ISA_use: Yes
  Tag_THUMB_ISA_use: Thumb-1
  Tag_FP_arch: VFPv2
  Tag_ABI_align_needed: 8-byte
  Tag_ABI_align_preserved: 8-byte, except leaf SP
  Tag_ABI_HardFP_use: Deprecated
  Tag_ABI_VFP_args: VFP registers

I think ld or dlopen check ".ARM.attributes" section and it fail when section is miss.

I like your perseverance 🥇

What's different between the two toolchains are the pre-built libs. The so link command is identical between the two.

I'm considering adding building Clang built-ins, and compiler-rt before the engine is linked. This would minimize toolchain pre-built and target dependency to just crt1/crti/crtn. I believe this will resolve the problem, as well as provide an optimized rt.

I'm out on vacation till mid next week, then I start a new job working with Flutter platform architecture! So the soonest I will start this is next weekend. I have the Clang build stages done in another project for Clang/MUSL, so it shouldn't be too bad.

It is very cool. this also unlocks AOT for emb flutter, because snapshot_gen creates a "bad" libapp.so.

Not sure what channel is not working, but I have AOT working in my Wayland flutter project. I have steps documented to generate an AOT here:

Hmm, i used gen_snapshot from channel=dev and it generated "bad" shared object. Ok i look at Wayland project.

@DisDis IIRC one of the host side tools does not build correctly. I pulled the "bad" host-side tool from a manual x86_64 engine build.
