I have submitted a FreeBSD bugzilla entry: Bug 215821 - head -r311147's bootstrapped ld for TARGET_ARCH=3Dpowerpc64 = produces kernel.full as a "shared object" for -pie instead of as a = "executable": booting the produced kernel crashes In essence what the .meta file for kernel.full shows as: CMD @ld -Bdynamic -T /usr/src/sys/conf/ldscript.powerpc64 -pie = --no-warn-mismatch --warn-common --export-dynamic --dynamic-linker = /red/herring -o kernel.full -X locore.o . . . (note the -pie) ends up producing: ELF 64-bit MSB shared object, 64-bit PowerPC or cisco 7500, version 1 = (FreeBSD), dynamically linked, interpreter /red/herring, not stripped instead of what it should have produced: ELF 64-bit MSB executable, 64-bit PowerPC or cisco 7500, version 1 = (FreeBSD), dynamically linked, interpreter /red/herring, not stripped The differences in content leads to the powerpc64 crashing at the start = of the produced kernel. This means needing to use devel/binutils and/or devel/powerpc64-binutils = instead (at least for ld). =3D=3D=3D Mark Millard markmi at dsl-only.net
