I have/had MQX 4.0.2 building with the Code Sourcery EABI arm-none package. I downloaded a 2012.03 tarball of the compiler tools. If I use the same tool for TOOLCHAIN_ROOTDIR, it barfs because the new MQX wants 4.7.4 and this one is 4.6.3. The stdbool.h header is not found, because each release uses a different 'lib/gcc/arm-none-eabi/version/include' directory. What is the proper tarball to download for this release of the MQX 4.1 for Linux release? The latest CodeSourcery arm-none-eabi gives a different GCC version, so I believe I need some older release (but newer than MQX 4.0.2/gcc 4.6.3). I am using the Vybrid Tower board and want to use the Cortex-A5.
