Re: SELinux compile errors

[Kerry Thompson <kerry@crypt.gen.nz>]

Aaarg. Sorry about the previous broken message, it seems that CTRL-V in KMail 
is 'Send', and not 'Paste bit of useful code'.

The same problem was raised a few weeks ago, it comes from ip_warn() in 
selopt_core.c having two arguments, while the macro definition in selopt.h 
has 3 arguments. Namely :

in selopt.h :

  #define ip_warn(iph, fmt, args...)                                     \
       do { printk(KERN_WARNING "%s: " fmt, __FUNCTION__, ##args);     \
            printk(" [%u.%u.%u.%u->%u.%u.%u.%u]\n",                    \
            NIPQUAD(iph->saddr), NIPQUAD(iph->daddr));                 \
       } while (0);

while the lines in selopt_core.c with compiler warnings are like :

    ip_warn(iph, "out of memory expanding skb\n");

... and your compiler is having a nasty reaction to it. You could try adding 
an extra parameter to the ip_warn() calls, like adding a NULL argument. Or, 
you could avoid the issue by building without labelled network support in 
your kernel config and avoiding selopt altogether.

Can you please identify which GCC compiler you're using ( 'gcc --version' ) ?
