Its $(PNG_LIBS) and the build works that way. Thanks for your helpful hint Andreas. -- http://fam-tille.de

As an alternative, the command: $ libpng-config --libs -lpng16 can be added to the command line; linked libraries should be the last argument. I believe it makes a sense, FH -- F.

You need to put libs into LIBS. I was checking this as well - seems here is something broken: # checks for libraries AC_SEARCH_LIBS([zlibVersion],[z]) AC_SEARCH_LIBS([sqrt],[m]) PKG_CHECK_MODULES([PNG], [libpng >= 1.2.0]) Any idea how to make sure the correct -lpng expression is added here? Kind regards Andreas. -- http://fam-tille.de
