Top post of llvm's lld status: Turns out various vintages of lld do not support R_ARM_V4BX *ABS* : https://bugs.llvm.org/show_bug.cgi?id=3D38303 Its shown example is one of the ones that I reported (pixman) but for building FireFox for Android (Linux context, not FreeBSD): QUOTE builds/worker/workspace/build/src/clang/bin/ld.lld: error: can't create = dynamic relocation R_ARM_V4BX against local symbol in readonly segment; = recompile object files with -fPIC >>> defined in = ../../gfx/cairo/libpixman/src/pixman-arm-neon-asm-bilinear.o >>> referenced by = ../../gfx/cairo/libpixman/src/pixman-arm-neon-asm-bilinear.o:(.text+0x4F0)= END QOUTE It also points out that: QUOTE Linking with -z notext is more explicit: /builds/worker/workspace/build/src/clang/bin/ld.lld: error: = ../../gfx/cairo/libpixman/src/pixman-arm-neon-asm-bilinear.o:(.text+0x4F0)= : unrecognized reloc 40 END QUOTE On 2018-Nov-16, at 12:34, Mark Millard <marklmi at yahoo.com> wrote: > [I add some objdump output from what was in the .tar archive for > the failure in the poudriere build (the 3 specific .o's).
