Attempting to build NPTL on x86-64 does this: LD libpthread-0.9.33.2-git.so /home/landley/aboriginal/aboriginal/build/simple-cross-compiler-x86_64/lib/../x86_64-unknown-linux/bin/ld: libpthread/nptl/libpthread_so.a(pthread_once.oS): relocation R_X86_64_PC32 against `__fork_generation' can not be used when making a shared object; recompile with -fPIC /home/landley/aboriginal/aboriginal/build/simple-cross-compiler-x86_64/lib/../x86_64-unknown-linux/bin/ld: final link failed: Bad value
This seems to be because an assembly file has explicitly non-pic code in it. Switching to LINUXTHREAD_OLD for the x86-64 architecture worked around the problem, but when I run my linux from scratch build under the result (same script which worked fine with the previous release), and perl goes: Running Mkbootstrap for threads::shared () chmod 644 shared.bs rm -f ../../lib/auto/threads/shared/shared.so cc -shared -O2 shared.o -o ../../lib/auto/threads/shared/shared.so chmod 755 ../../lib/auto/threads/shared/shared.so cp shared.bs ../../lib/auto/threads/shared/shared.bs chmod 644 ../../lib/auto/threads/shared/shared.bs make[1]: Leaving directory `/home/perl/dist/threads-shared' LD_LIBRARY_PATH=/home/perl ./perl -f -Ilib pod/buildtoc --build-toc -q ./perl: Can't resolve symbol '__pthread_mutex_lock' make: *** [pod/perltoc.pod] Error 1 Command exited with non-zero status 1 So linuxthreads_old is bit-rotted, and NPTL isn't working on x86-64 for me. Has anybody else hit this? I grepped for PIC in the other assembly files in the directory, and found a couple #ifdefs with @GOTOFF in the pic case, but none of them actually _dereference_ the symbol (just check whether the pointer is null), and google is being extremely unhelpful about @GOT and @GOTOFF and @PIC... Currently reading this in hopes SOMEBODY will explain what magic syntax I need... http://netwinder.osuosl.org/users/p/patb/public_html/elf_relocs.html Rob -- GNU/Linux isn't: Linux=GPLv2, GNU=GPLv3+, they can't share code. Either it's "mere aggregation", or a license violation. Pick one. _______________________________________________ uClibc mailing list uClibc@uclibc.org http://lists.busybox.net/mailman/listinfo/uclibc
