This should still work on Linux, however, it has been tested with MacOS only.

• An x86 PC running Linux, bash, gcc, GNU make or

• An Intel Mac with XCode and gettext (for msgfmt) installed

• The following tarballs, available from FTP sites the world over: binutils-2.21.1.tar.gz (the original kit used 2.10.1) gcc-2.95.3.tar.gz glibc-2.1.3.tar.gz glibc-crypt-2.1.tar.gz glibc-linuxthreads-2.1.3.tar.gz linux-2.4.3.tar.gz

• This kit, unlike the original, will attempt to build several additional useful bits: gettext-0.18.1.1.tar.gz glib-2.28.8.tar.bz2 libtool-2.4.tar.gz ncurses-5.2.tar.gz zlib-1.2.5.tar.gz

• Inside a checkout of this kit, add:

  • All the tarballs you've collected as above

  • Edit the PREFIX in the Makefile to dictate where your toolchain ends up

  • Also edit the path to msgfmt, needed to compile the language translations

  • Run make. This will build and install your toolchain (so you should run it as a user that can write to $PREFIX).

  • The resulting ARM Linux cross-compiler is newer than the version used to build V2.0 car player software. Of note, binutils and thus the assembler, particularly, are newer. You may have issues with older arm assembly. Typically, patches are available from upstream but posting to the empeg BBS may yield hints, if not.

• When cross-compiling, add $PREFIX/bin to your path.

  • Don't do it when you're not cross-compiling, in case you get the wrong cpp.
