So I zapped the gcc/g++, etc. from cygwin and did an install of mingw 64 bit outside of cygwin.  I added the big directory from that to my path.

I did the "./configure --with-cmp=yes" and it finished:

config.status: creating ecl/config.h

config.status: creating ecl/config-internal.h

Configuration complete. To build ECL, issue make in this directory.

But make is failing:

$ make

Obviously, on windows I still have to use cygwin as my shell because that's what configure expects.

Thoughts?

Thanks,

Garrett.

So the problem seems to be quite clear: your ecl build doesn't have the C compiler enabled.

When you configure the build, include --with-cmp=yes (or builtin).

./configure --prefix=/my/cygwin/prefix --with-cmp=yes

make && make install

Then C compiler should be available (you may still need to call (ext:install-c-compiler), you need

to check it yourself because I don't remember whether bytecodes compiler is installed by default

on cygwin, it is for msvc).

If it still doesn't work, please include a result of calling this code snippet:

(format t "~&~@{~12@A ~S~%~}"

        :version (lisp-implementation-version)

        :vcs-id (ext:lisp-implementation-vcs-id)

        :os (software-type)

        :os-version (software-version)

        :machine-type (machine-type)

        :features *features*)
