grsecurity forums

When trying to compile the 28-12-2009 version of grsecurity I got the error below:

Code: Select all

  CC      arch/x86/mm/fault.o
arch/x86/mm/fault.c: In function ‘pax_report_insns’:
arch/x86/mm/fault.c:1530: error: expected expression before ‘long’
make[2]: *** [arch/x86/mm/fault.o] Error 1
make[1]: *** [arch/x86/mm] Error 2
make: *** [arch/x86] Error 2


A quick cross-check with the pax-patch would lead to the assumption of an incomplete patch. Adding a few lines from pax-linux-2.6.32.2-test7.patch lead to the next compiling failure in the same file.

For now I'd rather use the old patch (20-12-2009) with the interdiff between pax-linux-2.6.32.2-test5.patch and pax-linux-2.6.32.2-test7.patch.
<edit>
Looking further it shows an interdiff over the 200912201010 version leads to a the same error.

Somehow I ended up producing the small and obvious patch on my slowest system
