This are follow up errors. The failing qemu-arm runs should have produced header files which provide those definitions. > > Not much knowledge on OpenEmbedded.

My investigation showed that qemu-arm can not execute any binary which is compiled with the compiler for Colibri-T20 and is linked with the -static flag. Even a simple hello world program does not work. When executing that hello world on the real hardware I also get a segmentation fault. I got java compiling and running by updating to the latest of meta-java, applying the patch which enables xawt and applying a patch which compiles all binaries without the -static flag. Compiling with dynamic linking however produces a binary which run on qemu-arm and on the target. Currently I have no idea why statically linked binaries fail. You likely want to use xawt. I do not think that the fix with removing '-static' should go into meta-java! cd stuff/meta-java git remote set-url origin git://git.yoctoproject.org/meta-java git fetch git checkout -b t20-test c600dd3 git am 0001-openjdk-7-enable-xawt.patch git apply remove_static_qemu_binaries.patch 0001-openjdk-7-enable-xawt.patch: https://github.com/MaxKrummenacher/meta-java/commit /ff0626363b3f11cc3435d3d081e2af93104faceb.patch 0002-qemu-binaries-remove-linking-with-static.patch: https://github.com/MaxKrummenacher/meta-java/commit /71ddc9a85509e6bd1ba1a3be2cc5e588e776f0b5.patch Regards Max -- _______________________________________________ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-devel
