++++++ This look very much as if you are passing the wrong libraries to the linker - or possibly you are passing the correct libraries, but in the wrong order (many linkers are sensitive to the order of libraries at link time - in particular, the gcc linker is, which is relevant to your use case.)
So - you need to change your linker invocation to match the list of libraries and their ordering that is used in the fltk makeinclude file, and hopefully that will get it working. ++++++ dear sir, thank you for your reply, i tried every connection to the FL .h files, i checked the .h files location copy it even into include (not FL directory) and changed the #include <...> adequatly but without success but as i mentoned in my first post i compiled the hello project well with g++ compiler from the command line g++ -I/usr/include/freetype2 -o hello hello.cxx /usr/lib/libfltk.a -lXft -lXinerama -lpthread -lm -lXext -lX11 my problem is how to compile the program from the netbeans? thank you for interest _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
