It's not even in our autobuilders AFAIK. I think we had one guy interested in the SPARC Leon support. I remember proposing to remove SPARC support entirely, and one person stepped up to say that he was using SPARC Leon stuff. See http://lists.busybox.net/pipermail/buildroot/2010-July/036382.html. I don't think Sam ever sent any patch related to SPARC support. However, Konrad Eisele sent a bunch of SPARC related patches. However, the last SPARC-related patches Konrad has sent have been sent on November 2010. He later sent some other patches (November 2011), but they were kconfig related, and were extensions to the kconfig language, something we're not ready to accept if they are not part of the upstream kconfig code in the Linux kernel. I've added Sam and Konrad in Cc to see if they are still using SPARC support, and whether it's worth adding a sparc sample to our autobuilders. Best regards, Thomas

It will need to be updated a bit because e.g. the gcc package has moved, but other than that are there reasons not to include it? Best regards, Thomas

I'm reviving this older thread. Are any of you still interested in SPARC support in buildroot (see above) ? Thanks, Thomas

Hi! We, Aeroflex Gaisler, and customers of ours are actively using buildrot. Our Linux build environment for Leon SPARC systems that we ship to customers are using buildroot. Furthermore, we also have customers that are using buildroot out of the box outside our build environment. So dropping SPARC support for buildroot would be a very bad thing. Thanks Sam for cc:ing some more Aeroflex Gaisler people. Best Regards, Andreas Larsson

This patch eliminates the long "depends on" lines in toolchain/gcc/Config.in by letting architectures specify from which GCC version the architecture is supported. Architectures that support only one specific version of GCC should bypass the GCC version selection mechanism.
