c++ - libpng "png_set_longjmp_fn" not found

Question

I'm using libpng from ubuntu and when I try to compile a c++ file I get

undefined reference to `png_set_longjmp_fn'

I'm using libpng version 1.6.8

If you are interested in reading the code please let me know, but I do not this has to do with my bad code.

Thank you in advance.

Perhaps you have built with libpng-1.6.8 but are linking to an earlier version of libpng. The "png_set_longjmp_fn()" API was introduced in libpng-1.4.x. Ubuntu 13:10 currently comes with libpng-1.2.49 (see /usr/include/libpng12), which does not supply png_set_longjmp_fn().
