It seems to get to the libc part and it then dies with this error message...
configure: error: No support for this host/target configuration.
Looking up in the output I see the following messages...
checking host system type... m68k-unknown-elf checking build system type... i686-pc-cygwin
Is this correct? Shouldn't the host be i686-pc-cygwin? I'm trying to develop a compiler that runs on my Windows box (with cygwin) and builds binaries for a Motorola coldfire embedded microcontroller with no operating system.
The above is correct when building code to run on the target, such as libstdc++-v3. Code which runs on cygwin, such as gcc, has a host (and, in this case, build) of cygwin and a target of m68k-elf. Code which runs on the m68k-elf target, such as libstdc++-v3, has a host of m68k-elf and a build of cygwin (and no target, since libstdc++-v3 is not itself a cross-compilation tool).

It seemed to be building libc at the time so that makes sense. I guess libc needs to have some sort of operating system defined?
I tried building with newlib using the --with-newlib switch and I got the following error message...
error: storage size of 're_comp_buf' isn't known
So maybe newlib will not run on a Coldfire processor? In any event, is there any way to tell the process not to compile any libraries? All of our software is custom written, so libraries are not really needed.
