[Freeciv-Dev] Re: building libpng on MinGW?

["Per I. Mathisen" <per@xxxxxxxxxxx>]

I tried to install the newest MinGW stuff on another computer, and I just
gave up. There is just too much broken stuff. The installation routine has
become completely FUBAR.

Cygwin is looking better as an alternative right now. So I tried it.

Pulled down the setup.exe from cygwin.org, installed pretty much
everything that could be relevant (30k files, yummy), had to edit
configure.ac like this

then ./autogen.sh --disable-nls --enable-client=win32 && make

produced this error:

associated macros have been defined in sys/types.

but it did start compiling. I guess there are lots of errors in the CVS
HEAD win32 client at the moment, and I am not going to fix them.

I'll look at producing GTK2 and SDL from Cygwin some other day.
