[PATCH 0 of 1 ] RFC - Add CUSTOM version for gcc, binutils, libc, gdb


Hi Yann, All,

Im sending the following feature addition as a request for interest on inclusion in CT-NG.

Similar to the existing KERNEL_LINUX_CUSTOM option, I added a 'custom' version option for gcc, binutils, eglibc, glibc, newlib and gdb. These can be grabbed from a common source directory, or specified individually as a directory path or path to a tarball.

This is useful for building against source during development on that component, or if the user wants to source control the component themselves using their own favourite system.

The resultant CT_SRC_DIR could be setup like the following example then, depending on versions selected / paths provided;

binutils-2.20.1a
eglibc-custom -> ~/src_dev/rebase/eglibc
gcc-custom -> ~/src_dev/gcc
gdb-custom -> ~/src_dev/gdb
gmp-5.0.2
linux-custom -> ~/src_dev/v2/linux
mpc-0.9
mpfr-3.1.0

I also considered making this depend on a DEVELOPER config option instead of just EXPERIMENTAL, would that be preferable?

thanks,
David
