A script to cross-compile GCC toolchain for various target architectures.

GCC cross-compiler building script

Supported architectures:

narke@vemst ~/P/gcc-cross-compiler> ./toolchain.py 
    Cross-compiler toolchain build script
    Syntax:
     ./toolchain.py [--no-install] <platform>
    Possible target platforms are:
     amd64      AMD64 (x86-64, x64)
     arm32      ARM
     ia32       IA-32 (x86, i386)
     ia64       IA-64 (Itanium)
     mips32     MIPS little-endian 32b
     mips32eb   MIPS big-endian 32b
     mips64     MIPS little-endian 64b
     ppc32      32-bit PowerPC
     ppc64      64-bit PowerPC
     sparc32    SPARC V8
     sparc64    SPARC V9

    The toolchain is installed into directory specified by the
    CROSS_PREFIX environment variable. If the variable is not
    defined, /usr/local/cross/ is used as default.
    
    If --no-install is present, the toolchain still uses the
    CROSS_PREFIX as the target directory but the installation
    copies the files into PKG/ subdirectory without affecting
    the actual root file system. That is only useful if you do
    not want to run the script under the super user.

Build a cross-compiler for 32-bit PowerPC without installing:

 ./toolchain.py --no-install ppc32

Build and install a cross-compiler for 32-bit ARM (default install directory is /usr/local/cross, specify another one by exporting CROSS_PREFIX environment variable):

 ./toolchain.py arm32
