chromium-x11 build error with Rust enabled

Hi,

since commit 0438fba
("chromium: Enable Rust") in meta-browser, I get this error
on several different chromium-x11 builds (i.e. Fedora 33 and
Fedora 39 hosts, mickledore and nanbield Yocto versions):

Obviously, using the previous commit works.

Hm, this should be avoided by this part of our changes to the Rust recipe.

Can you please run recipe-sysroot-native/usr/bin/rustc --print target-libdir --target x86_64-oe-linux-gnu and paste the output here? It should be a directory path. Please also paste the contents of that directory, it should contain some .rlib files (maybe other files as well).

[zboszor]

Sorry for the belated response.

Here's what you asked for:

$ bitbake -c configure chromium-x11
$ bitbake -c devshell chromium-x11
# cd ..
#
# recipe-sysroot-native/usr/bin/rustc --print target-libdir --target x86_64-oe-linux-gnu | sed "s:$(pwd)/::"
couldn't allocate absolute path for 'null'.

Hm, I think I know what the problem might be. Are you building for x64 on an x64 machine, i.e. not cross-compiling?

[zboszor]

Hm, I think I know what the problem might be. Are you building for x64 on an x64 machine, i.e. not cross-compiling?

Correct. But it should still be cross-compiling.

[MaxIhlenfeldt]

How is it cross-compiling when host and target architecture are the same?

In any case, can you please check if applying the following diff fixes the error:

[zboszor]

How is it cross-compiling when host and target architecture are the same?

Cross-compiling in Yocto is not just about a different CPU architecture, it's also about targetting a different OS altogether, that uses a different GLIBC version.

In any case, can you please check if applying the following diff fixes the error:

I will test it, thanks.

[zboszor]

It didn't help under mickledore. The same error occurred.

I am trying under nanbield now.

[MaxIhlenfeldt]

Did you do a full, clean build? I noticed when working on the patch to enable Rust that changes to the .bbappend file don't always get picked up and applied.

[zboszor]

I will try a clean build then.

[zboszor]

It didn't help. I tried this:

bitbake -c cleanall rust-native rust-llvm-native rust rust-llvm gn-native chromium-x11
bitbake -c compile chromium-x11

Same error.

[MaxIhlenfeldt]

Does ls -l recipe-sysroot-native/usr/lib/rustlib/x86_64-oe-linux-gnu/lib still show the same directory contents?

[zboszor]

FWIW, I have run repo sync for a fresh test, so it's chromium-x11 version 121.0.6167.184 now.

The directory contents are not the same.

Also, for some reason, there is no --target x86_64-oe-linux-gnu now. Instead, there is --target x86_64-unknown-linux-gnu.

Here's the directory contents for mickledore:
