On a system with very little software and no major desktop installed (only fluxbox) emerge xscreensaver fails to compile the demo program and bombs out with missing symbols. There is a warning message about no Motif or Gtk being installed. Reproducible: Always Steps to Reproduce: 1. Stage 3 build 2. emerge fluxbox 3. emerge xscreensaver Actual Results: In the emerge it fails like this: <SNIP> gcc -Wall -Wstrict-prototypes -Wnested-externs -Wno-format -std=c89 -U__STRICT_ANSI__ -L/usr/lib -o xscreensaver-demo-Xm prefs.o dpms.o remote.o exec.o ../utils/resources.o ../utils/usleep.o ../utils/visual.o demo-Xm.o demo-Xm-widgets.o -L/usr/X11R6/lib \ -L/usr/lib -lgdk_pixbuf -lgdk_pixbuf_xlib -L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule -lglib -ldl -lXi -lXext -lX11 -lm -lXmu -lSM -lICE -lXt -lX11 \ -lXext /usr/lib/gcc-lib/i586-pc-linux-gnu/3.2.2/../../../crt1.o(.text+0x18): In function `_start': : undefined reference to `main' prefs.o(.text+0x7a): In function `init_file_name': <SNIP> collect2: ld returned 1 exit status make[1]: *** [xscreensaver-demo-Xm] Error 1 make[1]: Leaving directory `/var/tmp/portage/xscreensaver-4.05-r3/work/xscreensaver-4.05/driver' make: *** [default] Error 5 !!! ERROR: x11-misc/xscreensaver-4.05-r3 failed. !!! Function src_compile, Line 82, Exitcode 2 !!! (no error message) I also notice up higher that there was a warning message: <SNIP> ################################################################# Warning: Neither Motif nor Gtk seem to be available; the `xscreensaver-demo' program requires one of these.

can you see what the output of `emerge -p motif` is? If motif isn't installed, suspect it might have been possible that it couldn't find the motif tarball on one of the sites and skipped that step of the installation.
Wizard root # emerge -p motif These are the packages that I would merge, in order: Calculating dependencies ...done! [ebuild R ] x11-libs/openmotif-2.2.2-r1 For kicks I then emerged motif. It installed without error as far as I could see, but emerge xscreensaver still failed. I notice that the message says it cannot find Motif, while this seems to install 'openmotif'. I doubt that's an issue, but I'm a newbie, so what do I know... ################################################################# Warning: Neither Motif nor Gtk seem to be available; the `xscreensaver-demo' program requires one of these.

I have had to rebuild it a few times to get 3D acceleration working on my Radeon 9000. I notice the file that's actually failing is: /usr/lib/gcc-lib/i586-pc-linux-gnu/3.2.2/../../../crt1.o /usr/lib/crt1.o does exist. Why would symbols not match up? (How do I view the symbols an object file is exporting?
gcc-config i586-pc-linux-gnu env-update source /etc/profile then try the emerge again, please
Wizard root # gcc-config i586-pc-linux-gnu * /usr/bin/gcc-config: Profile does not exist! Wizard root # gcc-config i586-pc-linux-gnu * /usr/bin/gcc-config: Profile does not exist! Wizard root # And then it still fails the emerge xscreensaver step later. I'll check my office machine to see what's in that file, but why would this machine not have one? Thanks!
FYI - I checked the office machine where xscreensaver did install and it gives me the same message: Gentoo1 postfix # gcc-config i586-pc-linux-gnu * /usr/bin/gcc-config: Profile does not exist!
This is all from the machine that worked. Possibly I needed to use gcc-config i586-pc-linux-gnu-3.2.2 That command passes on this machine. I'll try the machine that failed later this evening.

I tried the whole process again on the machine that fails. I used the i586-pc-linux-gnu-3.2.2 profile. The text of what happens follows at the end.

One other interesting thing. The file that fails is /usr/lib/crt1.o, built April 8th.

OK, this is understood. In debugging of another program I was having trouble with, I noticed that my global USE flages were -gtk. This apparently doesn't cause the xscreensaver to override, but does case it to fail. I changed the global flag to 'gtk' and xscreensaver builds and runs. Sorry for the use of bandwidth.
not a waste of bandwidth at all. in fact, you've brought to light a flaw in the ebuild.
OK then, glad this helped somehow. Thanks for sticking with me while I learned a bit. This Linux stuff is hard for us non-software backgroud, user-oriented people.
i've cleaned up the deps now in xscreensaver and this should now be fixed.
