YP Bug 10168 has the details. Short answer, build a target system that can compile.. grab the prelink sources, and then 'make check'. The reloc8.sh and reloc9.sh will fail. They both use "-Wl,-z,nocopyreloc" when linking. They worked in 2.1 and 2.0, no longer works in 2.2 (master). --Mark >> >> --Mark >> >>> >>> Changelog for the cross_prelink follows: >>> >>> Common changes: >>> >>> * Update configure.ac, libelf.m4 and */Makefile.am to avoid various auto* >>> warnings >>> * Fixed a few compile warnings >>> * Add testcase for YP 9131 - IFUNC problem >>> * Fix LD_PRELOAD issues >>> * Fix section ordering problem (required for binutils-2.22) >>> >>> Cross prelink specific changes: >>> >>> * rtld: resync to glibc-2.23 >>> * rtld: add additional debug scope support >>> * rtld: Add fix for YP 9131, IFUNC problem >>> >> >> -- >> _______________________________________________ >> yocto mailing list >> yocto@yoctoproject.org >> https://lists.yoctoproject.org/listinfo/yocto > -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
