Description Felix Janda 2014-11-23 12:09:16 UTC

76_all_use-new-ld-dtags.patch makes binutils ld generate DT_RUNPATH instead of DT_RPATH entries in the dynamic table. This is contraproductive for the dynamic linker of musl libc since it does not consider DT_RUNPATH at all. See the bottom http://www.openwall.com/lists/musl/2014/03/28/6 for a comparison of the path lookup between glibc and musl.

In particular, it makes binutils generated using crossdev on a musl based system not find the right libbfd.


Reproducible: Always

Comment 1 Felix Janda 2014-11-23 21:21:42 UTC

will be fixed in musl-1.1.6.

for posterity, DT_RUNPATH isn't a GNU-ism ... it's in the official ELF spec

Comment 3 Felix Janda 2015-06-14 14:41:58 UTC

http://refspecs.linuxbase.org/elf/elf.pdf

looks like the elf spec, but does not mention DT_RUNPATH.
(It mentionsDT_RPATH, though.)
