cargo cbuild on macOS results in openssl@1 errors

[GR899]

Using macOS on Apple Silicon with openssl installed via homebrew current openssl@3 located on my system at /opt/homebrew/Cellar/oopenssl@3/3.4.0

Trying to build a gstreamer/GTK plugin using directions from here:

(https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/#building)

Build results in the following:

cargo cbuild -p gst-plugin-gtk --prefix=/usr --libdir=/opt/homebrew/mygtkplugin
dyld[66859]: Library not loaded: @rpath/libssl.1.1.dylib
Referenced from: /Users/bob/.cargo/bin/cargo-cbuild
Reason: no LC_RPATH’s found
zsh: abort cargo cbuild -p gst-plugin-gtk --prefix=/usr

Is there a OPENSSL environment variable I should or could use to direct cbuild to use my current version of openssl@3 instead of openssl@1?

Thanks for any help or guidance.

cargo-c is the one provided by homebrew?

The openssl dependency comes from cargo itself, if cargo works then so should work cargo-c assuming you built it from source. If the homebrew cargo-c has the problem it should be discussed there.

I just tested and cargo install cargo-c and it is picking correctly the homebrew openssl.

Yes, I installed cargo using homebrew, however otool shows the following. Any suggestions on how I can resolve:

otool -L ~/.cargo/bin/cargo-cbuild

cargo uninstall cargo-c that version is not provides by homebrew.

[GR899]

Thank you. Just did this:

cargo uninstall cargo-c
    Removing /Users/bob/.cargo/bin/cargo-capi
    Removing /Users/bob/.cargo/bin/cargo-cbuild
    Removing /Users/bob/.cargo/bin/cargo-cinstall
    Removing /Users/bob/.cargo/bin/cargo-ctest

brew install cargo-c

brew info cargo-c
==> cargo-c: stable 0.10.9 (bottled)
Helper program to build and install c-like libraries
https://github.com/lu-zero/cargo-c
Installed
/opt/homebrew/Cellar/cargo-c/0.10.9 (11 files, 101.0MB)

Question - having done this, I'm still getting the openssl error. Do I need to add a path to my environment directly for pkg config or other to ensure cbuild picks it up?

When I removed c-build from cargo it removed ~/.cargo/bin files

/opt/homebrew/Cellar/cargo-c/0.10.9/bin

Thanks
