BUILDING THE R8C/M16C/M32C GNU TOOLCHAIN
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1. CD to the correct directory.
Change to the directory just above the NuttX installation. If <nuttx-dir> is
where NuttX is installed, then cd to <nuttx-dir>/..
2. Get the buildroot Module
Check out the misc/buildroot module (or download the appropriate buildroot package).
CVS checkout instructions:
cvs -d:pserver:anonymous@nuttx.cvs.sourceforge.net:/cvsroot/nuttx login
cvs -z3 -d:pserver:anonymous@nuttx.cvs.sourceforge.net:/cvsroot/nuttx co -P nuttx
3. Move the buildroot Source Tree and create the archive directory
mv misc/buildroot .
mkdir archive
The <nuttx>/../buildroot is where the toolchain is built;
The <nuttx>/../archive directory is where toolchain sources will be downloaded.
4. Configure and Make the buildroot
cd buildroot
cp configs/m32c-defconfig-4.2.4 .config
make oldconfig
make
This will download the large source packages for the toolchain and build the toolchain.
The resulting binaries will be under buildroot/build_m32c.
