Re: apitrace: undefined reference to `__libc_dlopen_mode', `__libc_dlsym'

I'd need help with the following issue with apitrace, which failed the mass rebuild with:

apitrace-9d42f667e2a36a6624d92b9bd697de097cc4e619/wrappers/dlsym.cpp:70: undefined reference to `__libc_dlopen_mode'
apitrace-9d42f667e2a36a6624d92b9bd697de097cc4e619/wrappers/dlsym.cpp:72: undefined reference to `__libc_dlsym'

The code triggering this is below. Have these symbols disappeared from libc resp is there any alternative?

I've raised this upstream but so far no activity [1]. I'm not really knowledgeable enough in this area to judge the best way to fix this. Is anyone able to help with this? Otherwise I'll have to orphain/retire apitrace for F35+.

According to the comments in https://github.com/apitrace/apitrace.git file wrappers/dlsym.cpp ,
the purpose is "to obtain the true dlsym" by explicit lookup in libdl.so.2, which is a library
that no longer exists in glibc-2.34, having been combined into libc.so itself.

The only legitimate way to find "the true dlsym" is to trust dl_iterate_phdr (/usr/include/link.h)
and call it, dig through all the Dynamic sections to find all the symbols named 'dlsym',
then choose the one you want: perhaps by being defined in a file whose DT_SONAME is "libc.so"
and having symbol version GLIBC_2.2.5 .

Because such code has not been contributed, then apitrace should be orphaned/retired in F35+.
