Created attachment 6348 [details] Test case This is a test case which demonstrates that something changed with ld between binutils 2.10.1 and 2.22 which resulted in a number of our BSPs not being able to do the transform from an ELF file to a compressed binary with a bootloader header. I have attached an unfortunately large file with the binaries that generate this failure. rtems 4.10 - binutils 2.20.1 with patches rtems 4.11 - binutils 2.22 with no patches With the same set of binary files to link. -bash-4.2$ /opt/rtems-4.10/bin/powerpc-rtems4.10-ld -o hello.ralf bootloader.o --just-symbols=hello.exe -b binary rtems.gz -T ppcboot.lds -bash-4.2$ /opt/rtems-4.11/bin/powerpc-rtems4.11-ld -o hello.ralf bootloader.o --just-symbols=hello.exe -b binary rtems.gz -T ppcboot.lds ppcboot.lds:97: undefined symbol `__rtems_start' referenced in expression -bash-4.2$ powerpc-rtems4.10-nm -g hello.exe | grep rtems_start 00000000 T __rtems_start The symbol is there but not found by the reference in ppcboot.lds. ========================================= These is the RTEMS RPM information so this can be traced to that. -bash-4.2$ rpm -qf /opt/rtems-4.10/bin/powerpc-rtems4.10-ld rtems-4.10-powerpc-rtems4.10-binutils-2.20.1-3.fc16.i686 -bash-4.2$ rpm -qf /opt/rtems-4.11/bin/powerpc-rtems4.11-ld rtems-4.11-powerpc-rtems4.11-binutils-2.22-1.fc16.i686 =========================================
