Of course, hard coding this CROSS_COMPILE value in Make.defs file will save
some repetitive typing.
NOTE: the CodeSourcery and devkitARM toolchains are Windows native toolchains.
The NuttX buildroot toolchain is a Cygwin toolchain. There are several limitations
to using a Windows based toolchain in a Cygwin environment. The two biggestg are:
1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
performed automatically in the Cygwin makefiles using the 'cygpath' utility
but you might easily find some new path problems. If so, check out 'cygpath -w'
2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic links
are used in Nuttx (e.g., include/arch). The make system works around these
problems for the Windows tools by copying directories instead of linking them.
But this can also cause some confusion for you: For example, you may edit
a file in a "linked" directory and find that your changes had not effect.
That is because you are building the copy of the file in the "fake" symbolic
directory. If you use a Windows toolchain, you should get in the habit of
making like this:
make clean_context; make CROSSDEV=arm-none-eabi-
An alias in your .bashrc file might make that less painful.
