That more or less worked, it still failed: /usr/bin/ld: /usr/local/src/glibc/build/nptl/tst-once5.o: relocation R_X86_64_32 against `.text' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: Nonrepresentable section on output collect2: error: ld returned 1 exit status But it does that after building the tst-robustpi8 thing, so I seem to have all I need here. > To run a single test, use this: > > bash -x testrun.sh nptl/tst-robustpi8 > > This is required because the test might not be compatible with the > installed glibc (some nptl tests are whitebox tests).

Indeed, that seems to work: $ ./elf/ld-linux-x86-64.so.2 --library-path .:./math:./elf:./dlfcn:./nss:./nis:./rt:./resolv:./crypt:./mathvec:./support:./nptl ./nptl/tst-robustpi8 tst-robustpi8: ../nptl/pthread_mutex_lock.c:424: __pthread_mutex_lock_full: Assertion `INTERNAL_SYSCALL_ERRNO (e, __err) != ESRCH || !robust' failed.
