Bug 22937 – x11-misc/xscreensaver with use +kerberos -krb4 fails to build

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description ajs 2003-06-16 11:22:47 UTC]

The xscreensaver package can detect krb5 and krb4 at ./configure time, but it
assumes that krb5 has been built with krb4 support (and the code seems to
require it). This is not the case for the USE='+kerberos -krb4' use-flags situation.

I think the correct thing to do in this situation is either fail when this
combination is detected, or disable the kerberos use-flag if krb4 isn't also
enabled (with a warning, naturally).

Reproducible: Always
Steps to Reproduce:
1. USE='+kerberos -krb4' emerge x11-misc/xscreensaver
Actual Results:  
# USE='+kerberos -krb4' emerge x11-misc/xscreensaver

thank you for your detailed report. i've chosen the second option for the moment, but i'm still not too happy with it. 

xscreensaver only seems to allow kerberos4 support only, or kerberos4 and kerberos5 support, but not kerberos5 only.

this will have to do for now until someone has time to patch passwd-kerberos.c to make a kerberos5 only version.

[Comment 2 Jason Pfeil 2003-06-18 09:19:58 UTC]

Funny.  When I did this, it still didn't work:

[Comment 3 Alastair Tse (RETIRED) 2003-06-18 09:24:17 UTC]

the fix is only in 4.10, it is currently the latest x86 stable xscreensaver. if you're using a diff arch open a new bug about it
