Same issue on 3.4.2. I do have `-Wl,--undefined-version` in my LDFLAGS and I can see that it was, in fact, used (as some aggressive configure scripts strip things they shouldn't).

Apply the attached patch if you're encountering the same issue.

I can confirm that the patch allows a successful, working build of audacity 3.4.2-r1 with llvm 18. As a related issue, lld fails to link audacity against media-libs/libsoundtouch[openmp], with the following error: ld.lld: error: undefined reference due to --no-allow-shlib-undefined: __kmpc_fork_call >>> referenced by /usr/lib/libSoundTouch.so (repeated for a few other references to __kmpc_*). Just use -openmp.
