/usr/bin/ld: cannot find -lcbqn: No such file or directory

[dslgr]

I'm trying to run cargo run --release but encountering the below error. I have bqn installed using nix home manager with the cbqn-replxx package. I'm using pop!_os 22.04. Does building beacon require also building cbqn instead of using the nix package?

  = note: /usr/bin/ld: cannot find -lcbqn: No such file or directory
          collect2: error: ld returned 1 exit status

warning: `beacon` (bin "beacon") generated 1 warning
error: could not compile `beacon` (bin "beacon") due to previous error; 1 warning emitted

Getting bqn version in zsh:

bqn --version
CBQN 0.3.0
built with FFI, singeli x86-64, replxx

cargo version 1.72.0 (103a7ff2e 2023-08-15)

Here's how I build the app on a generic linux distro (code from the GitHub workflow file):

LD_LIBRARY_PATH="${{ github.workspace }}/libcbqn.so -C strip=symbols" cargo build --release

Populate the LD-LIBRARY_PATH with a built or downloaded libcbqn.so library, and it should build.

That sent me on the right path! I still had trouble when using the nix store libcbqn.so, but I was ultimately successful when I followed these earlier steps from the github action: https://github.com/x86y/beacon/blob/main/.github/workflows/compile.yml#L31-L37
Then I ran RUSTFLAGS="-L {path to repo}" LD_LIBRARY_PATH="{path to repo}" cargo build --release
It only seemed to work without libcbqn.so in LD_LIBRARY_PATH. I additionally had to set the environment variable LD_LIBRARY_PATH to the same path.

I'm having a very similar problem (among several others) on Fedora 40. The project will only run if I explicitly provide the RUSTFLAGS="-L {path to repo}" LD_LIBRARY_PATH="{path to repo}" variables, as mentioned above. This is on a fresh installation of Fedora 40, having installed CBQN from git with make shared-o3 && sudo make install.

Did you try after or before the following commit? 61ad52e

I believe this commit should've fixed the library linking problems..
