I don't really understand; if it's not declared it wouldn't compile. An undefined reference surely means the declaration is somewhere, but not the definition. The function in question, png_set_expand_gray_1_2_4_to_8(), was added in 1.2.9 according to what I can find on the internet. But if yours is different and also really has no PNG_LIBPNG_VER_MINOR, then the test should be whether that's defined, whether PNG_LIBPNG_VER_MAJOR is more than 1, or is equal to 1 and PNG_LIBPNG_VER_MINOR is more than or equal to 3 (to be on the safe side). Does that sound correct? bwy -- The current release of Gnash is 0.8.7 http://www.gnu.org/software/gnash/ Benjamin Wolsey, Software Developer - http://benjaminwolsey.de C++ and Open-Source Flash blog - http://www.benjaminwolsey.de/bwysblog xmpp:b...@xabber.de http://identi.ca/bwy
