I've posted this linking error in github under the CXX project.. but was told it's a basic linking problem
build.rs snippet showing the linking
if let Some(build_info) = command.generate() {
println!("using conan build info");
build_info.cargo_emit();
// requires : sudo apt install libintelrdfpmath-dev
println!("cargo:rustc-link-lib=bidgcc000");
let twsapi = build_info.get_dependency("twsapi").unwrap();
My question or .. confusion is.. I can see in the output of cargo .. the needed library is indeed linked. I had this working with the same library name using GCC, Conan + Cmake .. any ideas ?
The linking line in output showing BigDecimal is getting linked
...
-l twsapi -l bidgcc000 -l static=twsapi-grpc-server
...
