the files in /usr/lib/debug are built with objcopy --only-keep-debug, so only include the debug info. the stripped files get a debug link added (objcopy --add-gnu-debuglink). For example, ld-2.12.1.so defines _rtld_global -- but > libc-2.12.1.so is looking for _rtld_global@@GLIBC_PRIVATE, so > _rtld_global@@GLIBC_PRIVATE > ends up undefined.

Did that work in the past? Can valgrind handle detached debug information? If not, then maybe call dh_strip in the eglibc package with -Xld-2.13.so Matthias _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
