Build error building in docker ekidd/rust-musl-builder --target x86_64-unknown-linux-musl

[JoshuaNitschke]

Hi, one of my dependencies has a dependency on num-integer.

This code compiles fine on mac, ubuntu, and windows when I run cargo build --release but I have been trying to build inside docker image ekidd/rust-musl-builder with cargo build --release --target x86_64-unknown-linux-musl and I get the following error:

Any ideas on how to fix this?

error: could not compile `num-integer` due to 4 previous errors

The error seems to indicate that the i128 feature was either enabled or autodetected for num-integer, but not for num-traits, which seems weird. There are sometimes problems with autocfg detection in cross-compilation, but that should be the same between num-integer and num-traits. I can build a hello-world in that container just fine with num-integer as a dependency.

Can you share the output of this command?

cargo tree --format "{p} : {f}"

[JoshuaNitschke]

@cuviper thanks for the response! Today, I was trying to get a small example of the issue going here https://github.com/JoshuaNitschke/rust-musl-builder_num-integer_example, but it builds as expected. Here is the cargo-tree output:

removed

[cuviper]

I guess you should add --target x86_64-unknown-linux-musl to that tree command, in case the target changes any dependencies. Please see if that's any different.

Another thing to look for are the build script outputs from num-integer and num-traits. There should be output and stderr files in a path like ./target/x86_64-unknown-linux-musl/release/build/num-integer-35c680a05bc94443/. The exact hash at the end of that path will vary depending on a lot of factors.

You can also build verbosely, cargo build -v -v ..., and look for lines like:

[num-traits 0.2.14] cargo:rustc-cfg=has_i128
[num-integer 0.1.44] cargo:rustc-cfg=has_i128

Or there may be visible errors if it didn't detect i128 support.

[JoshuaNitschke]

I reran with target and it was the same.

Interestingly, I have two folders: num_build_artifacts.zip

rust@9f69ab59e2b0:~/src$ ls ./target/x86_64-unknown-linux-musl/release/build/
num-integer-0694b7c89ce1bf38/

num-traits-0bb7be9c44b56e00/

I think we might be getting somewhere:

I don't understand the could not copy errors.

I will try building verbosely now.

[JoshuaNitschke]

I think i have resolved this by entering the container and chmoding the target folder... will confirm later today

[JoshuaNitschke]

Yep, sorry to bother, but your troubleshooting note about how to find the error was very helpful! I did not know about that output.
