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).
