[Discuss-gnuradio] problem configuring gr-video-sdl on Cygwin

[Walker, Robert CIV NAVSURFWARCENDIV Crane, Code 80EW]

I am having the same gr-video-sdl problem reported in the message below when running ./configure for gnuradio-3.0.3 on Cygwin:

http://lists.gnu.org/archive/html/discuss-gnuradio/2007-02/msg00067.html

The replies pointed out a problem with alloca.h and Cygwin but I didn't understand the proposed solution.  Can someone elaborate?  There appear to be links to a patch but I have no idea what to do with it.

A related issue I had is that before I even got to the point above, there was a problem with the fact that SDL was not installed on my machine.  I went back through the "Installing GNU Radio with Cygwin" installation instructions and noticed there is no mention of installing SDL.  Is this an oversight?  I tried following the SDL installation instructions on the "Installing GNU Radio with MinGW" page and that got me to the point of the alloca.h error.  If someone has a solution, any chance correct SDL installation instructions could be added to the Cygwin page?

One final thing is that I noticed the ./configure command line options on the GNU Radio MingW installation page included mention of SDL in a couple of places.  Those command line options follow for reference:

        --disable-gr-audio-windows
        --with-boost-include-dir=/usr/local/include/boost
        --with-sdl-exec-prefix=/usr/local
        CPPFLAGS="-I/usr/local/include -I/usr/local/include/SDL"
        LDFLAGS=-L/usr/local/lib

Does ./configure in Cygwin need similar SDL-related command line options?

Thanks,

Rob
