Neither of those has been released yet so no plans as of now. Nearly all the microblaze gcc patches are for gcc-4.8.0 on the trunk, several of them in fact. OK may be you should wait until fall release of yocto I've re-applied and ported all the existing patches that you've created for gcc-4.7.2 to gcc-4.7.3 (not yet tested). 4.7.3 is probably a snapshot you are talking about. We have moved away from snapshots for gcc since git repo for gcc is in terabytes and using svn did not go well with gcc recipe. If 4.7.3 is release in few days I will be happy to consider but as such we are staying with 4.7.2 So, I was wondering if you'd like me to try to get gcc-4.7.3 or gcc-4.8.0 built against the current poky master branch? You could try and may be even keep recipes in a layer and we can then progress them into OE-Core once the time comes. I can test ARM Cortex A9, ARM Cortex A8 and Microblaze at my end. Do let me know!

Re: [yocto] Patching gcc-4.7.2 to add support for Xilinx MicroBlaze
Hi Khem, After patching both gcc-4.7.2 and gcc-4.8.0, I get the following error. This looks like a common error, and I was wondering if there is something that needs to be additionally taken into consideration, in the poky gcc recipes (gcc-configure-*.inc) to get it to work for the microblaze processor? The output log is from the gcc-4.8.0 build, but the same message persists with the gcc-4.7.2 adapted build with the microblaze patches: | checking for microblaze-poky-linux-gcc... /tool/yocto/poky/build/tmp/work/microblaze-poky-linux/gcc-cross-initial/4.8.0-r01/gcc-4.8.0/build.x86_64-linux.microblaze-poky-linux/./gcc/xgcc -B/tool/yocto/poky/build/tmp/work/microblaze-poky-linux/gcc-cross-initial/4.8.0-r01/gcc-4.8.0/build.x86_64-linux.microblaze-poky-linux/./gcc/ -m32 -isystem/tool/yocto/poky/build/tmp/sysroots/spartan-6-sp601-microblaze/usr/include -B/tool/yocto/poky/build/tmp/sysroots/x86_64-linux/usr/microblaze-poky-linux/bin/ -B/tool/yocto/poky/build/tmp/sysroots/x86_64-linux/usr/microblaze-poky-linux/lib/ -isystem /tool/yocto/poky/build/tmp/sysroots/x86_64-linux/usr/microblaze-poky-linux/include -isystem /tool/yocto/poky/build/tmp/sysroots/x86_64-linux/usr/microblaze-poky-linux/sys-include --sysroot=/tool/yocto/poky/build/tmp/work/microblaze-poky-linux/gcc-cross-initial/4.8.0-r01/gcc-4.8.0/build.x86_64-linux.microblaze-poky-linux/tmpsysroot | checking for suffix of object files... configure: error: in `/tool/yocto/poky/build/tmp/work/microblaze-poky-linux/gcc-cross-initial/4.8.0-r01/gcc-4.8.0/build.x86_64-linux.microblaze-poky-linux/microblaze-poky-linux/libgcc': | configure: error: cannot compute suffix of object files: cannot compile | See `config.log' for more details. | make: *** [configure-target-libgcc] Error 1 | ERROR: oe_runmake failed | ERROR: Function failed: do_compile (see /tool/yocto/poky/build/tmp/work/microblaze-poky-linux/gcc-cross-initial/4.8.0-r01/temp/log.do_compile.32684 for further information) Best regards, Elvis Dowson ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto

Could you give me the url to your gcc-4.7.2 git repo, so that I can develop patches against it to add support for the Xilinx MicroBlaze soft-processor? I've hit the following bug http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54663 and the patches are available with this revision http://gcc.gnu.org/viewcvs?view=revisionrevision=195488 So, I'd like to back port it against the current gcc-4.7.2 recipe revision. Or else, I will have to do a git svn import of the source, and manually patch it using the current list of patches in the yocto recipe, which would take a couple of hours. So if I can have access to your repo, it will save me sometime! Thanks! Best regards, Elvis Dowson ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
