It looks like thumb has some unusual linking requirements that I'm not familiar with, so undefined functions (which are never actually called in the test) cause linker errors: /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-stage2/arm-eabi/libstdc++-v3/include/bits/iterator_concepts.h:155:(.text._Z6test06N8pr1056091IE+0x6): undefined reference to `pr105609::iter_move(pr105609::I const&)' /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/destdir/x86_64-pc-linux-gnu/arm-eabi/bin/ld: (_ZN8pr1056099iter_moveERKNS_1IE): Unknown destination type (ARM/Thumb) in /tmp/ccqKQGzN.o /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-stage2/arm-eabi/libstdc++-v3/include/bits/iterator_concepts.h:155:(.text._Z6test06N8pr1056091IE+0x6): dangerous relocation: unsupported relocation /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-stage2/arm-eabi/libstdc++-v3/include/bits/ranges_algobase.h:326:(.text._Z6test06N8pr1056091IE+0xc): undefined reference to `pr105609::I::operator++()' /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/destdir/x86_64-pc-linux-gnu/arm-eabi/bin/ld: (_ZN8pr1056091IppEv): Unknown destination type (ARM/Thumb) in /tmp/ccqKQGzN.o /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-stage2/arm-eabi/libstdc++-v3/include/bits/ranges_algobase.h:326:(.text._Z6test06N8pr1056091IE+0xc): dangerous relocation: unsupported relocation /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/destdir/x86_64-pc-linux-gnu/arm-eabi/bin/ld: /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-stage2/arm-eabi/libstdc++-v3/include/bits/ranges_algobase.h:323:(.text._Z6test06N8pr1056091IE+0x16): undefined reference to `pr105609::I::operator==(pr105609::I) const' /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/destdir/x86_64-pc-linux-gnu/arm-eabi/bin/ld: (_ZNK8pr1056091IeqES0_): Unknown destination type (ARM/Thumb) in /tmp/ccqKQGzN.o /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-stage2/arm-eabi/libstdc++-v3/include/bits/ranges_algobase.h:323:(.text._Z6test06N8pr1056091IE+0x16): dangerous relocation: unsupported relocation I think I should be able to workaround this.
