Scripts to build binutils, gcc (w/o libc) and gdb for xtensa. $ # check config file (vars BINUTILS, GCC, GDB, PARALLEL) $ ./prepare.sh target-variant $ ./fixup-gdb.sh # optional, for compatibility with QEMU $ ./build.sh target-variant

You either need unpacked/overlayed binutils, gcc and gdb in the current directory, or archives thereof (unpacked and overlayed by prepare.sh).

Further steps to build uClibc, binutils, and gcc for linux. $ # check config file (vars LINUX and UCLIBC) and config.uClibc $ ./build-linux.sh target-variant

You need unpacked linux and uClibc sources in the current directory.
