Iceman85 reacted to energia in Is Energia purely for 64-bit CPU architectures?
You bring up a good point. I had this question coming at some point. I would have to look into if it is possible to build a 32-bit compatible toolchain on a 64-bit mac (don't have access to 32-bit mac). I won't be able to get to this for next 2 weeks though.
I do have a build script that I use to build the toolchain. You could try that to build your own 32-bit toolchain. You will have to install X-Code which you can download from App Store (http://itunes.apple.com/us/app/xcode/id ... ls=1&mt=12).
Let me know if you want to go down that path and I will send you the script.
