The origin of the problem is a change (between fltk1.1-1.1.7 and fltk1.1-1.1.8~rc1) in the output of fltk-config.
With libfltk1.1{,-dev} version 1.1.7-7 installed, I get $ fltk-config --use-gl --libs /usr/lib/libfltk.a /usr/lib/libfltk_gl.a $ but with revision 1.1.8~rc1-2 I get $ fltk-config --use-gl --libs /usr/lib/libfltk.a /usr/lib/libfltk_gl.a $ The octplot configure script gets tripped up by the extra linefeed, so the resulting Makefile has LIBS = /usr/lib/libfltk.a /usr/lib/libfltk_gl.a -lfltk_gl -lfltk -lGLU -lGL -lm -lfreetype -lz instead of LIBS = /usr/lib/libfltk.a /usr/lib/libfltk_gl.a -lfltk_gl -lfltk -lGLU -lGL -lm -lfreetype -lz I humbly suggest reassigning to package fltk1.1, although I could also make an argument that autoconf should deal with this case. There's not really anything to fix in octplot, which just does LIBS="$LIBS `$FLTK_CONFIG $fltkconf_args --use-gl --libs`" in configure.ac. - Larry -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
