Hi again,

I just cloned the git repo and compiled the program using the
`libXrandr-devel` package on Fedora. The compilation seemed to be fine:

    slock build options:
    CFLAGS = -std=c99 -pedantic -Wall -Os -I. -I/usr/include
-I/usr/X11R6/include -DVERSION="1.2" -DHAVE_SHADOW_H
    LDFLAGS = -s -L/usr/lib -lc -lcrypt -L/usr/X11R6/lib -lX11 -lXext
-lXrandr
    CC = cc
    CC slock.c
    CC -o slock

And it was fast … C++ and templates definitly kill the compile time :-/.

Anyway, it does not start. It says

    cannot disable the out-of-memory killer for this process

and bails with exit code 1. From the Fedora package specification I
think that the following lines change *something*:

    %global _hardened_build 1

    export CFLAGS="%{optflags}"
    export LDFLAGS="%{?__global_ldflags}"

    make %{?_smp_mflags}

I have no clear idea of what those options really are in detail. Perhaps
something with SELinux which prevents writing to `/proc`?

Version 1.2 does not compile directly, when I tried that I get the
following:

    slock build options:
    CFLAGS = -std=c99 -pedantic -Wall -Os -I. -I/usr/include
-I/usr/X11R6/include -DVERSION="1.2" -DHAVE_SHADOW_H
    LDFLAGS = -s -L/usr/lib -lc -lcrypt -L/usr/X11R6/lib -lX11 -lXext
    CC = cc
    CC slock.c
    In file included from slock.c:26:0:
    config.h:1:30: error: 'NUMCOLS' undeclared here (not in a function)
     static const char *colorname[NUMCOLS] = {

    slock.c: In function 'lockscreen':
    slock.c:215:60: error: 'COLOR2' undeclared (first use in this function)
      XAllocNamedColor(dpy, DefaultColormap(dpy, lock->screen), COLOR2,
&color, &dummy);

                        ^
    Makefile:18: recipe for target 'slock.o' failed
    make: *** [slock.o] Error 1


All in all I cannot get the repo version to work, sorry. :-(
