libsdl2 currently does not handle the failures that occur due to shared memory in case of remote hosts where it should ideally switch to socket based writing when a failure is seen with shared memory. Consider a scenario where a qemu build is done with graphics support on a build machine and then accessed remotely using ssh. If the remote host's X presents MIT-SHM as an extension, launching qemu fails with
runqemu - ERROR - Failed to run qemu: X Error: BadValue Request Major code 130 (MIT-SHM) Request Minor code 3 () This is most often seen when the remote machine doing ssh is a Ubuntu 20.04. The libsdl2 native are mainly used for qemu at this time so it is a major usecase. A report of such a failure was also presented at https://lists.yoctoproject.org/g/poky/topic/78854857 Signed-off-by: Awais Belal <awais_be...@mentor.com> --- meta/recipes-graphics/libsdl2/libsdl2_2.0.14.bb | 1 + 1 file changed, 1 insertion(+) diff --git a/meta/recipes-graphics/libsdl2/libsdl2_2.0.14.bb b/meta/recipes-graphics/libsdl2/libsdl2_2.0.14.bb index 872592fdae..54556abb27 100644 --- a/meta/recipes-graphics/libsdl2/libsdl2_2.0.14.bb +++ b/meta/recipes-graphics/libsdl2/libsdl2_2.0.14.bb @@ -65,6 +65,7 @@ PACKAGECONFIG[wayland] = "--enable-video-wayland,--disable-video-wayland,wayl PACKAGECONFIG[x11] = "--enable-video-x11,--disable-video-x11,virtual/libx11 libxext libxrandr libxrender" EXTRA_AUTORECONF += "--include=acinclude --exclude=autoheader" +CFLAGS_append_class-native = " -DNO_SHARED_MEMORY" do_configure_prepend() { # Remove old libtool macros. -- 2.17.1
