Profiler build failure on Debian Buster with CMake

[de-passage]

On the master branch, building the profiler alone with CMake fails on Debian Buster with X11 for ~2~ 1 reasons:

1. ~Wayland is incorrectly selected despite LEGACY=ON being given in the CMake configuration. This leads to searching for wayland-scanner which is apparently not available on Debian Buster.~
2. The final link step is missing -ldl, leading to undefined reference to symbol 'dlclose@@GLIBC_2.2.5'

~I fixed problem 1 by adding the following to profiler/CMakeLists.txt and reconfiguring:~ (PEBKAC)

if (LEGACY)
    set(USE_WAYLAND OFF)
else()
    set(USE_WAYLAND ON)
endif()

I went around 2. by running the link command manually adding -ldl to it. I guess there's a target_link_libraries(... dl) missing somewhere.

The resulting binary appears to be working.

Commands reproducing the problem:

$ cmake -B build-profiler -DCMAKE_BUILD_TYPE=Release -G Ninja -DCMAKE_CXX_FLAGS="-Wl,-rpath,/opt/gcc-14.2/lib64" -DLEGACY=ON -S profiler # Error 1.
$ cmake --build build-profiler # Error 2

I fixed problem 1 by adding the following to profiler/CMakeLists.txt and reconfiguring:

There's an equivalent condition already in cmake/config.cmake, which is included at the top of profiler's CMakeLists.txt. Can you step through the CMake configuration (for example with the "Configure with CMake Debugger" command in VS Code) to see what's the problem here?

The second problem is an interesting one to figure out.

I tried starting from scratches and error 1 went away. I guess LEGACY=OFF got cached and never reset correctly. Sorry about that. I have reproduced error 2 however. I don't have much more information unfortunately.

Here's the full error message:

Edit: FWIW adding dl to target_link_libraries in profiler/CMakeLists.txt fixes it.

Yes, but the question is, why? Tracy doesn't use dlclose, so the problem seems to be somewhere else.

I'm running into the same problem
