glibc added a gettid() wrapper with version 2.30; earlier glibc and uclibc do not have it. That can be fixed by conditionally including the inline function if on glibc lower than 2.30 or another libc; for reference on how to detect that, see how kernel self tests do it [1]. As of the FOPTS changes: are those necessary for rtla to build, or were you just using them for easier debugging? AFAIK rtla shouldn't depend on unwind tables or stack protection for functionality. > > But it is not enough, as executing rtla fails with a segfault. > I can dump a core, but I could not manage to build gdb for my board so I > can't debug it (I don't know how to debug a coredump without gdb !). > > JM > I have seen a similar libtraceevent-related rtla segfault recently on ARM64, which was fixed by updating libtraceevent to a version that includes the fix. Such issues are caused by the files for kernel tracepoint tracefs having different contents on different architectures, exposing bugs. I see Steven has already fixed one of the issues on m68k [2].
