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
