I have the following problems compiling an SDL application in windows, does
anyone know what these errors mean, and how best to deal with them? Nothing
I do seems to get rid of them. I’ve tried using both gcc and g++, but both
do hte same thing (someone had suggested they do different things a while
ago).
This only occures when I include a library I compiled for SDL (gil_app.o),
when I try the source file demonstrated in the visual C++ example
(http://pgdc.purdue.org/sdltutorial/sdl_setup.html), it works fine using the
same flags/options as TEST COMPILE 2 and TEST COMPILE 3.
