You can use docker to cross compile (supposed to work on any Linux): $ make docker-test-build@debian-powerpc-cross If you don't want to rebuild all the images the following commands are faster to modify the codebase and rebuild more frequently: $ mkdir -p build_ppc32 $ docker run --rm -it -v `pwd`:`pwd` -w `pwd`/build_ppc32 -u `id -u` qemu:debian-powerpc-cross sh -c '../configure $QEMU_CONFIGURE_OPTS' [...] $ docker run --rm -it -v `pwd`:`pwd` -w `pwd`/build_ppc32 -u `id -u` qemu:debian-powerpc-cross make -j4 subdir-ppc-softmmu [...] CC ppc-softmmu/gdbstub-xml.o CC ppc-softmmu/trace/generated-helpers.o LINK ppc-softmmu/qemu-system-ppc ../migration/postcopy-ram.o: In function `mark_postcopy_blocktime_end': /source/qemu/migration/postcopy-ram.c:717: undefined reference to `__atomic_fetch_add_8' /source/qemu/migration/postcopy-ram.c:738: undefined reference to `__atomic_fetch_add_8' ../migration/postcopy-ram.o: In function `mark_postcopy_blocktime_begin': /source/qemu/migration/postcopy-ram.c:651: undefined reference to `__atomic_exchange_8' /source/qemu/migration/postcopy-ram.c:652: undefined reference to `__atomic_exchange_8' /source/qemu/migration/postcopy-ram.c:661: undefined reference to `__atomic_exchange_8' collect2: error: ld returned 1 exit status Makefile:193: recipe for target 'qemu-system-ppc' failed make[1]: *** [qemu-system-ppc] Error 1 Makefile:391: recipe for target 'subdir-ppc-softmmu' failed make: *** [subdir-ppc-softmmu] Error 2
