Can't create Dockerfile for ubuntu with aarm64 architecture

[turian]

Unfortunately, /root/DawDreamer/thirdparty/libfaust/download_libfaust.sh only works for i86. (arm64 is not supported yet: grame-cncm/faust#951)

I am tearing my hair out trying to build a Dockerfile to build everything under arm64 Ubuntu.

Here is what I currently have:

    && cd DawDreamer \

    && git submodule update

RUN echo "\nChecking DawDreamer/Builds/LinuxMakefile directory..." >> /root/build_logs.txt \

## Test import of DawDreamer and log the output
RUN { python3 -c "import dawdreamer"; } >> /root/build_logs.txt 2>&1 || echo "Import failed" >> /root/build_logs.txt

## Final command
#CMD ["cat", "/root/build_logs.txt"]

It ultimately fails with

I have been tearing my hair out trying to figure out why the linked libfaustwithllvm has a bogus symbol.

Any idea how to fix this?

[turian]

I also try the standard Dockerfile for DawDreamer, even though it for i86, hoping to run through emulation mode.

But now I get this:

import dawdreamer
Traceback (most recent call last):

Perhaps I can disable Faust in DawDreamer? I am only interested in loading presets and running them

[DBraun]

I haven't tried it in a while, but you should be able to skip everything Faust related by removing the BUILD_DAWDREAMER_FAUST preprocessor in DawDreamer.jucer and regenerating the Makefiles. Editing the makefile by other means should be doable do. I think I'll try to do more architecture support toward the end of December.

[DBraun]

In your first post I noticed that the script uses both python3.10 and python 3.8. Your second post uses Python 2.7.

If that doesn't fix it, something could be going wrong with make -f Make.llvm.static, so running that in isolation and looking at debug print statements or logs could help.

[turian]

Sorry my mistake, I have been experimenting with ubuntu22.04 and 20.04 and python2 and python3 and experiencing no success.

But I have the same error that I originally posted, sorry for not rigorously testing what I commented. I have tried all variation though.

I can remove the BUILD_DAWDREAMER_FAUST in DawDreamer.jucer but I don't know how to regenerate the Makefiles.

[DBraun]

No worries. Can you try removing "-DBUILD_DAWDREAMER_FAUST" in https://github.com/DBraun/DawDreamer/blob/main/Builds/LinuxMakefile/Makefile

[turian]

I tried that but it still has a lot of faust stuff it's pulling in:

8746e3c89c10 ~/DawDreamer/Builds/LinuxMakefile # make
Linking DawDreamer - Dynamic Library
/usr/bin/aarch64-unknown-linux-gnu-ld.bfd: cannot find -lfaustwithllvm: No such file or directory
clang-16: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [Makefile:122: build/libdawdreamer.so] Error 1

I've even resorted to trying to make a Gentoo Dockerfile. But Gentoo doesn't want to build static LLVM:
https://discourse.llvm.org/t/llvm-static-libs/38255
https://lists.llvm.org/pipermail/llvm-dev/2015-September/090589.html

I would really love a way to build DawDreamer that doesn't depend upon faust, this has been really gnarly

[DBraun]

Sorry I overlooked another thing. Try removing -lfaustwithllvm from the Makefile too. If there are other issues just keep deleting anything Faust related from the Makefile.

[turian]

Okay so your suggestion helped. (p.s. building libfaustwithllvm is super gnarly and I couldn't figure it out after trying a variety of methods)

This Dockerfile builds and I can import dawdreamer:
