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 libpng12.
This is the call we make:
png_structp png_ptr = png_create_read_struct (PNG_LIBPNG_VER_STRING, (png_voidp)0, 0, 0);
Anybody who knows anything about it, or knows what more information I should provide?
Simple testcase (compilable snippet), please?
Gerrit
Some simple code: #include <stdio.h> #include <png.h>
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
Thanks /Marco
