Hmm, it builds fine here, and I can't see where -Werror=implicit-function-declaration comes from. Can you attach a build log with V=1 in MAKEOPTS and config.log from the xdm-1.1.11_build directory? Created attachment 351974 [details]

config.log
Added build log with V=1 in MAKEOPTS and config.log -Werror=implicit implies -Werror=implicit-function-declaration and that's getting added by xorg-macros.m4. X11 guys, please add --disable-selective-werror to your configure options. Building with -Werror is against our policies. Feel free to fix the underlying problem of course. I can't reproduce this bug. If it is a Werror problem, this bug should be marked RESOLVED INVALID, right ? No, I can't reproduce it either, but it doesn't matter. People are hitting it. I think I've found the solution.
Create file: /etc/portage/env/xdm_no_error.conf
With: CFLAGS="${CFLAGS} -Wno-all" In it.
Then, add: x11-apps/xdm xdm_no_error.conf
into file: /etc/portage/package.env
After that xdm should build successfully.
Maybe that ugly solution, but at least now i can build xdm.
The problem does only manifest if libbsd is installed, because arc4random (and setproctitle too) are used without proper #include directives. xdm does not attempt to use arc4random if libbsd is not installed on Linux systems. Patch was applied to 1.1.11-r3 and also sent upstream. |
