No, the problem is that these functions are private and are not exported from the dll lib, so I need to link libpng staticallz to get the functions, but I want to link against the dynamic lib. I found one reference in the archives how to substitute png_info_init with png_create_info_struct() but nothing about png_read_destroy(). Anyway, thank you for your comment, please keep communication on the cygwin list as long as it is ontopic there.
