I enable: BR2_PACKAGE_HOST_QEMU=y BR2_PACKAGE_HOST_QEMU_LINUX_USER_MODE=y BR2_PACKAGE_HOST_QEMU_SYSTEM_MODE=y BR2_PACKAGE_HOST_QEMU_VDE2=y on the config. Host QEMU builds and works with VNC, but "-display sdl" is not available. The configuration logs say: SDL support no However, if I do ./configure directly from host on the QEMU tree, SDL support is available, and builds with it, since I do have the libsdl2-dev package installed in Ubuntu 17.04. I think the problem is the: PKG_CONFIG="/home/ciro/bak/git/linux-kernel-module-cheat/buildroot/output/host/usr/bin/pkg-config" and: /home/ciro/bak/git/linux-kernel-module-cheat/buildroot/output/host/usr/bin/pkg-config sdl2 is wrongly false, while on host: pkg-config sdl2 is true. A dirty workaround is: diff --git a/package/qemu/qemu.mk b/package/qemu/qemu.mk index 66efcba..1e09ea4 100644 --- a/package/qemu/qemu.mk +++ b/package/qemu/qemu.mk @@ -74,6 +74,7 @@ HOST_QEMU_SYS_ARCH ?= $(HOST_QEMU_ARCH) ifeq ($(BR2_PACKAGE_HOST_QEMU_SYSTEM_MODE),y) HOST_QEMU_TARGETS += $(HOST_QEMU_SYS_ARCH)-softmmu +HOST_QEMU_OPTS += --enable-sdl --with-sdlabi=2.0 HOST_QEMU_OPTS += --enable-system --enable-fdt HOST_QEMU_DEPENDENCIES += host-dtc else
qemu_x86_64_defconfig is the base config.
We don't want to do this, because it would mean host-qemu would rely on your host installed SDL libraries, which is not what we want. In the current state of things, I don't think we are going to provide a host-qemu package that has SDL/graphics support as that would require to package too many host libraries in Buildroot.
