[PATCH 1/2] Documentation/HOWTO: Use a more recent gcc + binutils

Show all headers | View raw

Debian Woody is pre-gcc3.2 and Sarge ships 3.3 gcc. I tried to compile
v4.8.6 on Sarge failed due to binutils:
|arch/x86/entry/entry_32.S: Assembler messages:
|arch/x86/entry/entry_32.S:379: Error: invalid character '"' in operand 1
|arch/x86/entry/entry_32.S:454: Error: too many positional arguments
|arch/x86/entry/entry_32.S:580: Error: too many positional arguments
|arch/x86/boot/bioscall.S:68: Error: `68(%esp)' is not a valid 16 bit base/index expression

among other errors. Sarge comes with GNU ld version 2.15 with is not
recent enough. I don't see those errors on Etch which ships version 2.17
and therefore I raise the limit to 2.17.
gcc is a different story. 3.3 It throws a lot of warnings
|include/linux/irq.h:402: warning: parameter has incomplete type
|include/linux/irq.h:403: warning: parameter has incomplete type
|drivers/gpu/drm/i915/i915_gem_gtt.h:312: warning: parameter has incomplete type

during the compile and fails then with
| cc1: error: unrecognized option `-Wno-override-init'

or later with

|lib/lzo/lzo1x_compress.c: In function `lzo1x_1_do_compress':
|lib/lzo/lzo1x_compress.c:132: error: implicit declaration of function `__builtin_ctz'

Etch (with gcc v4.1.2) gets to compile the kernel without plenty of
warnings and it also chokes on Wno-override-init but that one could be
easily fixed if we want to keep v4.1 as the minimum.
So I think raising the bar to gcc v4.1 isn't that bad given that the
last release of gcc 4.1 was on February 13, 2007.
