how can I use gcc to create .so file about lodepng HOT 2 CLOSED

Thanks for your report,

Is there any way in your setup that you can get a stack trace of the C code that runs?

In C, the signature of lodepng_decode32_file is:

unsigned lodepng_decode32_file(unsigned char** out, unsigned* w, unsigned* h,
const char* filename);

Are width and height pointers in your code? If "width = 0" means it's a null pointer, that will cause a crash since it wants to write the width to the unsigned integer it points to. Same also for raw_rgba_pixels where it wants to output a pointer to a a buffer it allocates inside. How are pointers handled in this setup?

Thanks
