am i wrong ?

how can't link the shared project correctly?

thanks!

Reproduce the issue with the provided Premake Lua script and inspect the generated projects and build/debug outputs. Run ldd on extstr_main and compare its recorded shared-library path with the location of libextstr.so; done means the executable resolves the shared project without the incorrect relative path.
