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
