2.6.18.2: cannot compile with gcc 3.0.4

2.6.18.2: cannot compile with gcc 3.0.4

[Ludovic Drolez]

Hi !

When I try to compile the latest kernel with 3.0.4, I get a parse error:

In file included from include/asm/suspend.h:7,
                  from include/linux/suspend.h:5,
                  from arch/i386/kernel/asm-offsets.c:11:
include/asm/i387.h:55: warning: `always_inline' attribute directive ignored
include/asm/i387.h: In function `__save_init_fpu':
include/asm/i387.h:58: parse error before '[' token
include/asm/i387.h:68: parse error before '[' token
include/asm/i387.h: At top level:
include/asm/i387.h:96: warning: `always_inline' attribute directive ignored

With gcc 2.95.4, I get a "compiler too old" errors, and the same parsing 
error... so, gcc 3.0.4 (Debian Woody) will be also in the compiler blacklist, 
or can it be fixed ?

Cheers,

If you had bothered to read Documentation/Changes then you would have
seen that the current minimal required gcc version is 3.2 :

Current Minimal Requirements
============================

Upgrade to at *least* these software revisions before thinking you've
encountered a bug!  If you're unsure what version you're currently
running, the suggested command should tell you.

o  Gnu C                  3.2                     # gcc --version

Ok sorry, I didn't see the change between 2.6.15 and 2.6.16.
Maybe a test should be added in linux/compiler-gcc3.h, to have the same 
warning as with gcc 2.xx ?

Untested, but something like this should do it.

The kernel doesn't compile with GCC <3.2, do not allow it to succeed if GCC 
3.0.x or 3.1.x are used.
