Hmm, working fine here (both rhel-7 and fedora-27 testbuild container, default build flags). The symbol in question should be provided by qemu: kraxel@fedora-64bit ~/projects/qemu/build/fedora# objdump -x audio-pa.so | grep audio_pt_unlock_and_signal 0000000000000000 *UND* 0000000000000000 audio_pt_unlock_and_signal kraxel@fedora-64bit ~/projects/qemu/build/fedora# objdump -x x86_64-softmmu/qemu-system-x86_64 | grep audio_pt_unlock_and_signal 00000000004735f0 g F .text 0000000000000067 audio_pt_unlock_and_signal Possibly your linker throws it away, thinking there is no user because of the modular drivers? cheers, Gerd
