As reported in bug #8206, the mplayer configure script fails to detect the availability of X11 header/library if the X.org development packages are not installed on the build machine. This is due to the logic used by the mplayer configure script, which looks like this: for I in $(echo $extra_cflags | sed s/-I//g) /usr/include ; do if test -f "$I/X11/Xlib.h" ; then _x11_headers="yes" So, in other words, it: 1/ Parses the --extra-cflags option, and finds the -I options in there. 2/ Looks in /usr/include Since $(STAGING_DIR)/usr/include is in the compiler built-in search path for headers, we currently don't explicitly pass it in --extra-cflags, so mplayer only looks in /usr/include. If you have X11 headers there thanks to being installed on your build machine, everything works fine (the rest of the build logic really uses the headers and libraries of the cross-compiler). But if you don't have X11 headers in /usr/include, the configure scripts assumes X11 is not available. Since fixing the hand-written configure script of mplayer, hosted in a Subversion repository, is beyond sanity, we simply work around this problem by passing the appropriate -I$(STAGING_DIR)/usr/include option in --extra-cflags. Before this patch, during the configure script: Checking for X11 headers presence ... no (check if the dev(el) packages are installed) Checking for X11 ... no (check if the dev(el) packages are installed) And then, the mplayer binary: 0x00000001 (NEEDED) Shared library: [librt.so.0] 0x00000001 (NEEDED) Shared library: [libz.so.1] 0x00000001 (NEEDED) Shared library: [libpthread.so.0] 0x00000001 (NEEDED) Shared library: [libdl.so.0] 0x00000001 (NEEDED) Shared library: [libm.so.0] 0x00000001 (NEEDED) Shared library: [libc.so.0] With this patch, during the configure script: Checking for X11 headers presence ... yes Checking for X11 ... yes And then, the mplayer binary: 0x00000001 (NEEDED) Shared library: [librt.so.0] 0x00000001 (NEEDED) Shared library: [libz.so.1] 0x00000001 (NEEDED) Shared library: [libpthread.so.0] 0x00000001 (NEEDED) Shared library: [libdl.so.0] 0x00000001 (NEEDED) Shared library: [libm.so.0] 0x00000001 (NEEDED) Shared library: [libXext.so.6] 0x00000001 (NEEDED) Shared library: [libX11.so.6] 0x00000001 (NEEDED) Shared library: [libXinerama.so.1] 0x00000001 (NEEDED) Shared library: [libXxf86vm.so.1] 0x00000001 (NEEDED) Shared library: [libc.so.0] Fixes bug #8206 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com> |

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
