The reason is command make --jobs=4 -f ./objs/Makefile srs trying to link the program when error encounters.
I do a little workaround made the compile goes.

So the problem is the autoconf seemed missed the dependency of libatomic add -latomic in the configure file did fix the problem
I recommend that adding SrsLinkOptions="${SrsLinkOptions} -latomic"; on configure file line 210. Then restart the configure mission. then make command did successful.

Does the SRT library depend on -latomic? If we use ./configure --srt=off, can it succeed? We need to know specifically which library depends on -latomic, rather than directly adding this option to solve the problem.

Not only do we need to know how to do it, but we also need to understand why.

On the newset version of libsrt I found a note in srt/srtcore/atomic.h which trying to warp the atomic header in a uniform statis. It says:

   // NOTE: GCC compiler built-ins for atomic operations are pure
   //    compiler extensions prior to GCC-4.7 and were grouped into the
   //    the __sync_* family of functions. GCC-4.7, both the c++11 and C11
   //    standards had been finalized, and GCC updated their built-ins to
   //    better reflect the new memory model and the new functions grouped
   //    into the __atomic_* family. Also the memory models were defined
   //    differently, than in pre 4.7.
   // TODO: PORT to the pre GCC-4.7 __sync_* intrinsics. In the meantime use
   //    the POSIX Mutex Implementation.

So on raspberry piOS 10, gcc version is gcc8.3. as it said, typically all versions later than gcc4.7 atomic features were implemented as __atomic_* function families. which is the symbol ported out from libatomic.so.

Thanks for the feedback.

A suitable solution would be to try and detect the environment. If there is a need to link the atomic library, then add this link option.

Could you consider submitting a Patch to SRS?

As a workaround, you can set the ldflags, which is passed to linker:

./configure -h |grep ldflags
  --extra-ldflags=<ELDFLAGS> Set ELDFLAGS as LDFLAGS.

For example:

./configure --extra-ldflags="-latomic"

If it's a common flags for RaspberryPI, I think it's acceptable to do this automatically.
