Hi

I was having a similar problem trying to build a perl module on windows
with cygwin. Did you resolve this using any of the suggestions below?

- symlink from /usr/include/win32api/windows.h win32.h did not work.
- The faq says that cygwin includes it but I don't know where.

here is my error:

jhall ~/src/perlmodsrc/Win32-API-0.20
$ make
gcc -c  -DPERL_USE_SAFE_PUTENV -DHAS_SBRK_PROTO -fno-strict-aliasing  -DUSEIMPORT
LIB -O2   -DVERSION=\"0.20\" -DXS_VERSION=\"0.20\" -I/usr/lib/perl5/5.6.1/cygwin/CORE  API.c
In file included from API.xs:39:
/usr/lib/perl5/5.6.1/cygwin/CORE/perl.h:1746: win32.h: No such file or
directory

make: *** [API.o] Error 1

Whatever. 'sokay.

No. perl.h has the following stanza:

#ifdef WIN32
#  include "win32.h"
#endif

That's "win32.h", not <win32.h>.  There's a file in
<perl-src>/win32/win32.h, which is probably copied up to the toplevel
during a win32-native configure. (I'm just guessing here)

The correct fix is probably to replace the #ifdef statement with:

#if defined(WIN32) && !defined(__CYGWIN__)

But the presence of that #include "win32.h" has never cause me any build
trouble; it's odd that it would only cause difficulties when building
DBD::ODBC but not other modules.

either.
