Compiled with:
gcc -o pngtest pngtest.c -mno-cygwin -mwin32 -mwindows -lpng

Not a cygwin problem then.
cheers,

So where
Some simple code:
#include
#include
int main(int argc, char **argv)
{
png_structp png_ptr = png_create_read_struct
(PNG_LIBPNG_VER_STRING, NULL, NULL, NULL);
return 0;
}
Compiled with:
gcc -o pngtest pngtest.c -mno-cygwin -mwin32 -mwindows -lpng

After successfully porting our application from Linux to cygwin, most of
the functions work, except for one thing - png images. As soon as I call
png_create_read_struct, the application will imediately hang and start
using up all available CPU power. This happens with both libpng10 and
libpng1
I might have solved this by adding -mno-cygwin, -mwin32 and -mwindows to
the linker flags too. It doesn't run (eats up all CPU power instead),
but at least it compiles.

(I posted this in cygwin.talk, but then I realized that this was a much
more suited place)
I'm trying to get a fairly large C++ project to compile using the mingw
tools in cygwin. I've sorted out most of the errors so far, but now I'm
stuck on the executable linking .
