Description:
------------
Under CygWin, when compiling with an extension that uses C++, configure reports "C++ compiler cannot create executables" and exits (./configure --with-myextension).
I'm using the latest version of CygWin with gcc 3.2 20020927.

After uncommenting the corresponding line in the configure script, I was able to successfully build PHP with my C++ extension.

I originally used php 4.3.2, the latest CVS version didn't work either.

cygwin is not a supported build environment for PHP.
We didn't write your extension.
You didn't give enough info for us to know what is going wrong.

This is not a bug in php, so marking as bogus.
If you have problems developing extensions, ask on the internals mailing list.

If CygWin is not a supported build environment, how come the configure script explicitly checks for it: "checking for CygWin environment".

And PHP can be compiled on CygWin with no problems as long as you don't use C++. And even if you use C++, there are no problems except that configure thinks the C++ compiler is incapable of producing executables. So I had to modify configure not to exit after detecting that the compiler is supposedly incapable of producing executables.

It really has nothing to do with my extension at all. You can use any (C++) extension that has PHP_REQUIRE_CXX() in the config.m4 file.

And why do you assume I am having trouble developing extensions? As I said, it worked fine after modifying configure.

cygwin tests are from libtool/autoconf, those we can't remove. We do NOT support Cygwin, period.
(and it's likely that your config.m4 is borked, and that is definately NOT our problem.

Thank you very much, that clarifies it.
