Linking to c library fails in devcontainer environment

[vithalsm]

I am trying to test a rust application linking with a C based shared lib built by . Both C library and rust being compliled in devcontainer environment (Ubuntu 20.04 LTS based).
build.rs has required changes to link to the lib and specify the path. While same things works well when build in my linux dev machine, 'cargo build' fails when tested in devcontainer running on same dev machine. Error:
error: linking with cc failed: exit status: 1
...
= note: /usr/bin/ld: /work/rust-app/target/debug/deps/rust_app-f390bc1401f0732c.3zy2ogu46grmljay.rcgu.o: in function rust_app::main': /work/rust-app/src/main.rs:14: undefined reference to from_the_library'
collect2: error: ld returned 1 exit status

= note: some extern functions couldn't be found; some native libraries may need to be installed or have their path specified
= note: use the -l flag to specify native libraries to link
= note: use the cargo:rustc-link-lib directive to specify the native libraries to link with Cargo (see https://doc.rust-lang.org/cargo/reference/build-scripts.html#cargorustc-link-libkindname)

error: could not compile rust-app (bin "rust-app") due to previous error

build.rs::
fn main() {
println!("cargo:rustc-link-lib=rtest");
println!("cargo:rustc-link-search=/home/vmohare/rust/rust-conan/libs");
}

Hi @vithalsm, this is the GitHub repository of the crates.io package registry. Your issue above seems unrelated to that though. A better place for questions like this is e.g. https://users.rust-lang.org/
