cross-compilers are available.
If you are running Debian 9 "Stretch" you can install the latest
cross-compiler directly from the package archive:
sudo apt install gcc-m68k-linux-gnu g++-m68k-linux-gnu binutils-m68k-linux-gnu
If you are running Debian 8 "Jessie" or earlier, you can build m68k
cross-development tools with the help of the
project. See also the
pages in the Debian wiki.
project is another good way to build your own toolchain.
You can obtain cross-compiler binaries from
but be warned that the GCC 4.6.3 binary at this link is known to have issues
when building Linux/m68k.
If you decide to build a cross-compiler yourself, please note that
GCC 2.95.2 has been reported to miscompile some things. These issues seem
to have been resolved in Debian's compiler sources. But note that this
compiler is too old to build kernel releases newer than v2.
Obsolete cross compiler builds have been archived on the
