With xorg-x11-6.8.0-r3 installed, gdm-2.6.0.6 ebuild on amd64 won't compile. The configure script looks for an undefined function XdmcpFlush(). Interestingly, it looks like that function really does exist: % objdump -t /usr/X11R6/lib/libXdmcp.a | grep XdmcpFlush 0000000000000000 g F .text 0000000000000026 XdmcpFlush % grep -n XdmcpFlush /usr/X11R6/include/X11/Xdmcp.h 133:extern int XdmcpFlush(int fd, XdmcpBufferPtr buffer, XdmcpNetaddr to, int tolen); The error from gdm's configure script is: checking for X11/Xdmcp.h... yes checking for XdmcpFlush in -lXdmcp... no configure: error: XDMCP support requested but XDMCP libraries not found This seems related to <http://bugs.gentoo.org/show_bug.cgi?id=69244>, but I created a new bug because this is gdm failing rather than kdm.

I don't know if this is relevant, but I also have emul-linux-x86-xlibs-1.2-r1 installed, which provides its own libXdmcp.a. But it, too, appearse to contain this function: % objdump -t /emul/linux/x86/usr/X11R6/lib/libXdmcp.a | grep XdmcpFlush 00000000 g F .text 00000047 XdmcpFlush
Created attachment 52246 [details] configure log for broken gdm-2.6.0.6 build This is still broken. Here's the config.log from ./configure, in case it helps.
I get the exact same problem. 2004.3r1 w/ x86_64-pc-linux-gnu-3.4.3 sources. Get it for previous ebuilds as well. - Mac

this bug is very old, guessing that it is fixed now. please reopen if that's not the case

After re-emerging xorg-x11, gdm emerged fine. I don't know what caused this glitch. So you can let this bug leave as WORKSFORME. Sorry for bothering
