Description Nischala Yelchuri 2022-05-20 19:11:06 UTC 
When trying to build cargo-cross-canadian, do_compile fails if a dependency is added to one of its dependencies.

For example, adding the following to the curl recipe:

+DEPENDS += "libssh2"
+EXTRA_OECONF:append = " --with-libssh2"

causes the build for bitbake cargo-cross-canadian-aarch64 to fail.

cargo-cross-canadian is failing to find libssh2.h. 

Manually adding nativesdk-libssh2 to cargo-cross-canadian DEPENDS fixes the issue. Is this the expected outcome or should libssh2 dependency be automatically included since it is a dependency for curl?
Comment 1 Richard Purdie 2022-05-26 12:56:58 UTC 
cargo shouldn't be auto-detecting dependencies like this but should only be building the things it is configured with. We should probably have some explicit configuration in the cargo recipe?
Comment 2 Yash Shinde 2022-09-13 16:50:49 UTC 
With latest sources pulled in and trying to build 'cargo-cross-canadian-aarch64' with the given specifications in the description for curl recipe, the given variant is not found-


 ERROR: Nothing PROVIDES 'cargo-cross-canadian-aarch64'. Close matches: 
  gcc-cross-canadian-aarch64
  gdb-cross-canadian-aarch64
  go-cross-canadian-aarch64


git log shows the cargo-cross-canadian support was dropped and SDK env moved to rust-cross-canadian with commit 251f55374d26b5c24d8833aa87c95432be8b81b2 (cargo: Drop cross-canadian variant and fix/use nativesdk).

And, bitbake build with 'rust-cross-canadian-aarch64' command is done successfully. So, this issue is not reproducible with latest sources pulled with rust-cross-canadian-aarch64 command.

Can this issue be closed?

Issue closed as it cannot be reproduced with latest sources
Comment 4 Yash Shinde 2022-09-19 05:57:14 UTC
