Yes, I think so. ;o) I'm sorry, I totally missunderstood meaning of options. You are right, the second line configures without using system libpng. Now the main libraries are built, but there is a problem regarding fluid: Linking fluid... /usr/bin/ld: ../lib/libfltk.a(fl_font.o): undefined reference to symbol 'FcPatternAddDouble' /usr/bin/ld: note: 'FcPatternAddDouble' is defined in DSO /lib/libfontconfig.so.1 so try adding it to the linker command line /lib/libfontconfig.so.1: could not read symbols: Invalid operation This is not a problem to me (an old version of fluid works), but maybe this problem will also appear to other users. >> I think, that's it: I installed libpng-2:1.5.10-1 and now I see, >> there is a "Old version of libpng, needed to run old binaries", >> libpng10-1.0.59.

To me it looks like a new major version - libpng-2, not libpng(-1). _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
