I can't understand why it doesn't work. I can compile vim in cygwin in 32 bits, but don't know how to do it in 64 bits.
I have to change the name of the compiler tough.
See
https://groups.google.com/d/msg/vim_use/80X4edvhEeo/u7oYDye-5oYJ
for what I usually when compiling vim in cygwin.

The original message was also sent to vim-dev. I have confirmed that
/something/ in my cygwin setup has changed, but I have no idea what. I
was able to compile patchlevel 712 on October 24th, but when I backed
my local repository out to the same patchlevel this morning it now
fails to compile even 712, with the same error shown above.

I would like to note that I have /never/ been able to get
Make_ming.mak to work under Cygwin, although other people appear to
know the "magic incantations." If someone could give me a hint,
perhaps it would work where Make_cyg.mak now fails.

I was able to get Make_ming.mak to compile a native Windows gvim.exe
using Cygwin's MinGW packages as long as I don't try to include Ruby.

When I try to include Ruby I get the following errors:

I wonder if this would be a problem if I used a non-Cygwin MinGW
distribution, but this has become too much trouble already. Hopefully
someone can suggest a fix, or I'll just live without the Ruby
interpreter. (+perl/dyn and +python/dyn were included without issue.)

I've been seeing this for a year with a Cygwin GCC build, starting
with the Ruby 1.9 series. Something changed so that Vim's build no
longer finds the necessary Ruby libraries, for me starting with
ruby.h. I've spent hours (one today!), but never could track it down.

I think in my case it's not a problem of finding the libraries (or
includes) but that the .h files included for Ruby have "collisions"
with files already included by Cygwin's standard .h files, so the
compile errors out.

I did some Googling, and found that this problem doesn't only exist
with compiling Vim, and someone suggested that it's the fault of the
Ruby .h files, which should only be defining these things if they're
not already defined. If this is the case, I wonder if the Vim sources
could somehow be tweaked to work around this problem. My C is getting
increasingly rusty, and my competence was never beyond a beginner's
level anyway, so at this point I'm not really sure how to attempt it.

Hi,

I think that Make_cyg.mak needs some additional include dirs for ruby 1.9.
After applying the attached patch, I can compile with the following command:

$ make -f Make_cyg.mak CC=gcc-3 CXX=g++-3 RUBY='/path/to/ruby1.9.3' RUBY_VER=19 RUBY_VER_LONG=1.9.1

Using i686-pc-mingw32-gcc instead of gcc-3 also works,
but i686-w64-mingw32-gcc doesn't seem to work for ruby interface.

Best regards,
Ken Takata

And yet I still get the undefined reference to _pow error, regardless
of which version of gcc I use.

Looking at Make_mvc.mak, the extra directories are only used when the
Ruby version is 1.9 or later. Not for 1.8.

Oh, I didn't notice that.
How about this patch?

And I think this is the same for Make_ming.mak.

Hmm, strange.
The symbol _pow is usually defined in a library libmsvcrt.a which
is linked by default.
Can you compile a program just using pow()?

For example:
$ cat a.c
#include <math.h>
int main()
{
return (int) pow(2, 3);
}

$ i686-pc-mingw32-gcc a.c (or gcc-3 -mno-cygwin a.c)

$ ./a; echo $?
8

Thanks,
Ken Takata

Yes, this works fine.
