Compile error for x86 code
Posted: Sat May 24, 2008 12:59 pmI ran into a problem with compiling 2.6.25.4-grsec-200805181334.
The compilation ends with:
When I look at the code the error seems located at the following code (line 782, I compile without SMP support):
Changing the xcs to cs produces compiling code.
I build the 32-bit code on a 64-bit Athlon using the ARCH=i386 environment setting.
The "stable" grsec-patch compiles without a hitch (2.6.24.7-grsec-200805121951)
In 2.6.24.7 it says in ./arch/x86/mm/fault_32.c
