3 months ago @jean-airoldie I patched with the fix you mentioned in https://github.com/jean-airoldie/zeromq-src-rs/issues/42#issuecomment-2210501073, which looked promising in that the cargo_metadata from cc includes instructions that would add the file to the link paths. I still can't get it to cross-compile successfully though - I've attached a full log to the issue description above, the primary error appears to still be the same.

Coming from #42:
Hi, I'm having the same issue with targeting aarch64-unknown-linux-gnu. I've gathered that the "original" issue was https://github.com/jean-airoldie/zeromq-src-rs/issues/28 about strlcpy-detection in the original C-library's cmake build system vs. here. I've also followed https://github.com/erickt/rust-zmq/issues/385 to this commit and understood that the fix that was made there to support cross-compilation requires using a version of zeromq-src >= 0.3, which is not yet used by a published zmq release.
However, I then tried to locally patch the
zmq-sysdependency to point to the branch from https://github.com/erickt/rust-zmq/pull/386 usingThis was successful in causing the version of zeromq-rs used during the build to be bumped to zeromq-src-0.3.2+4.3.5 and would compile on the host (as does the older version), but still fails to cross-compile to aarch64 giving
The error clearly references main in src/strlcpy.c. I guess (as @jean-airoldie mentions) it is expected that the "test build" of that file would fail on the target if its glibc does not define strlcpy, but it appears that somehow that also causes the entire build to fail.
