The virtio-gpu.h file defines a macro VIRTIO_GPU_FILL_CMD which includes a call to qemu_log_mask, but does not include qemu/log.h. In a default configure, it is lucky and gets qemu/log.h indirectly due to the 'log' trace backend being enabled. If that trace backend is disabled though, eg ./configure --enable-trace-backends=nop Then the build will fail: In file included from /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c:19:0: /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c: In function ‘virgl_cmd_create_resource_2d’: /home/berrange/src/virt/qemu/include/hw/virtio/virtio-gpu.h:138:13: error: implicit declaration of function ‘qemu_log_mask’ [-Werror=implicit-function-declaration] qemu_log_mask(LOG_GUEST_ERROR, \ ^ /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c:34:5: note: in expansion of macro ‘VIRTIO_GPU_FILL_CMD’ VIRTIO_GPU_FILL_CMD(c2d); ^~~~~~~~~~~~~~~~~~~ /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c:34:5: error: nested extern declaration of ‘qemu_log_mask’ [-Werror=nested-externs] In file included from /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c:19:0: /home/berrange/src/virt/qemu/include/hw/virtio/virtio-gpu.h:138:27: error: ‘LOG_GUEST_ERROR’ undeclared (first use in this function) qemu_log_mask(LOG_GUEST_ERROR, \ [snip many more errors] Signed-off-by: Daniel P.
