IIRC 4.7 should have good support for things like fixed point arithmetic, and other fun stuff. I can't find any information describing which version of Mac OS X those gcc binaries need.

The CodeSourcery toolchain is still supported as well. Happy hacking! Update: Unfortunately, the OS X link posted earlier is down: <a href="https://github.com/MikeSmith/gcc-arm-embedded-macosx" rel="nofollow">https://github.com/MikeSmith/gcc-arm-embedded-macosx</a> is now a 404. It looks like the MikeSmith GitHub account no longer exists. Anyone know of another source of OS X builds? If not, LeafLabs will end up providing them, I suppose. mbolivar on "Linux + Windows GCC binary builds for Cortex-M, -R targets" http://forums.leaflabs.com/topic.php?id=1717#post-11880 Fri, 20 Jul 2012 17:40:04 +0000 mbolivar 11880@http://forums.leaflabs.com/ I looked over your changes; they seem fine (no promises! I've never used the other toolchain). The CodeSourcery drops are a huge PITA, so I'll definitely look into this. javi9231 on "Linux + Windows GCC binary builds for Cortex-M, -R targets" http://forums.leaflabs.com/topic.php?id=1717#post-11829 Thu, 19 Jul 2012 02:59:16 +0000 javi9231 11829@http://forums.leaflabs.com/ Don't worry ventosus, I usually take a lot of risks...
