hehe this one is very nice : Making all in x11 make[5]: Entering directory `/usr/var/tmp/portage/app-emulation/vice-1.21/work/vice-1.21/src/arch/unix/x11' Makefile:377: *** multiple target patterns. Stop. make[5]: Leaving directory `/usr/var/tmp/portage/app-emulation/vice-1.21/work/vice-1.21/src/arch/unix/x11' having a closer look at it : src/arch/unix/x11/Makefile:377 libx11ui.a: $(libx11ui_a_OBJECTS) $(libx11ui_a_DEPENDENCIES) and then : libx11ui_a_DEPENDENCIES = vidmode.o dga1.o dga2.o xrandr.o openGL_sync.o rsync://rsync.europe.gentoo.org/gentoo-portage in Makefile.am now : libx11ui_a_DEPENDENCIES = @FULLSCREEN_DRIVERS@ @SYNC@ hmm I think I know the cause... in configure.in : SYNC="openGL_sync.o $SYNC"; hey, it takes the SYNC variable from environment ! SYNC is defined only here, so changing that line to : SYNC="openGL_sync.o"; allowed me to compile
thanks...
