2008.10.14 18:00 "debugging on Windows", by Rajmohan Banavi
Hi,
Just started using libtiff 3.8.2 on Windows (gnuwin32.sourceforge.net) and
am seeing an unhandled exception when I call the api - TIFFPrintDirectory().
I have pasted the code below. Even if I provide stdout as the 2nd parameter
to the function TIFFPrintDirectory(), i see the same crash. Please let me
know what I am missing. Further, just wanted to know how easy is it to build
a debug version of the libs for Windows?
Thanks.
