Dropping --enable-trace-backend=dtrace makes things work AFAICT. This is on f33 dnf builddep -y qemu # to get all the fedora package build deps cd qemu.git git checkout v5.1.0 ./configure --target-list=x86_64-softmmu --disable-werror --enable-modules --enable-trace-backend=dtrace make ./x86_64-softmmu/qemu-system-x86_64 -vga qxl # ./x86_64-softmmu/qemu-system-x86_64 -vga qxl Failed to open module: /root/qemu.git/x86_64-softmmu/../ui-gtk.so: undefined symbol: qemu_xkeymap_keymap_semaphore Failed to open module: /root/qemu.git/x86_64-softmmu/../ui-sdl.so: undefined symbol: qemu_sdl2_process_key_semaphore Failed to open module: /root/qemu.git/x86_64-softmmu/../hw-display-qxl.so: undefined symbol: qemu_qxl_render_blit_semaphore qemu-system-x86_64: QXL VGA not available So nothing specific to qxl, seems all modules are busted. I tried downgrading gcc to f32 versions, no difference. Same after downgrading binutils. Downgrading glibc downgrades the whole distro so I didn't attempt it Output of this looks similar on f33 and f32: nm {hw-display-qxl.so,x86_64-softmmu/qemu-system-x86_64} | grep qemu_qxl_spice_destroy_surfaces_complete_semaphore Any suggestions?
