successfully gotten to compile but project in CXX fails at linker stage

EMCP commented 1 year ago

I just wanted to checkin if I am doing something wrong with my conan package.. I have updated my recipe to call out the system library dependency.. but CXX still cannot find my libraries built.. everything works in C++ just fine so I am a bit lost

I added the system library dep like so

def package_info(self):
    self.cpp_info.libs = ["twsapi"]
    self.cpp_info.system_libs = ["bidgcc000"]

https://stackoverflow.com/a/74475762/389976

but seems CXX just cannot find what C++ 's GCC normally can via regular conan

Any thoughts? if it's clearly not a conanRS issue feel free to close, thanks for looking

For me, the solution was the following:

1) Make sure your building static instead of shared libs

# in conanfile.txt
[options]
your_lib:shared=False

2) cargo_emit() will result in cargo:rustc-link-lib=your_lib, which does not take into account that you built a static lib (this looks like a bug to me)

To fix this, you need to manually print the correct line:

// in build.rs
println!("cargo:rustc-link-lib=static=your_lib");

thank you @tom-anders for the static option tip.. I have added that.. I have paired back the project to just see if I can get it to build with a hello world CXX now.. full post is in discourse https://users.rust-lang.org/t/cxx-noob-with-simple-hello-world-not-finding-my-library-function/100957

I think I can close this ticket until that more basic issue is resolved now.. but I think your tip has helped
