[Comment 1 Samuli Suominen (RETIRED) 2012-05-15 21:43:45 UTC]

sys.c has both stdlib.h and fnctl.h in #include, as well as config.h

see, man 3 posix_openpt

i'm unsure about correct fix :/

I would also suggest passing the following configure flag:

  --disable-selective-werror
                          Turn off selective compiler errors. (default:
                          enabled)

[Comment 4 Hristo Venev 2012-12-16 13:22:00 UTC]

Build fails with gcc 4.8 with no extra cflags. Patch fixes it.
luit should depend on x11-misc/util-macros because it is required for running aclocal when there is a patch.

*** Bug 463666 has been marked as a duplicate of this bug. ***

[Comment 6 Chí-Thanh Christopher Nguyễn 2013-04-12 12:07:07 UTC]

The build problem is fixed now. The -Werror=... issue should probably go into a separate bug report.
