[maemo-developers] [maemo-developers] Linux kernel source code

[From: Kimmo Ahola]

Hello All,

looks like I have to answer this myself because I have not received any other 
help instructions. The same happened when I was asking where is the WLAN 
driver sources for 2.6.16 kernel, see 
http://maemo.org/pipermail/maemo-developers/2006-August/005049.html 
The correct answer to this is: 
https://garage.maemo.org/plugins/scmsvn/viewcvs.php/?root=cx3110x
I have not received any reason for this, does somebody knows the reason?

The solution to my problem (below) was to change the compiler environment 
(toolchain). Looks like the kernel (OK, only WLAN driver) is compiled with 
the 3.4 toolchain (scratchbox-toolchain-arm-gcc3.4.cs-glibc), not with the 
scratchbox-toolchain-cs2005q3.2-glibc-arm which I used and was suggested in
http://www.maemo.org/platform/docs/tutorials/Maemo_tutorial.html#Installation

The kernel compilation Wiki-page proposes to use 
scratchbox-toolchain-arm-gcc3.4.cs-glibc compiler, but in that page all other 
instructions was for IT2005 (and Maemo 1.1) and I mistakenly believed that 
suggestion was also outdated (so that was my mistake).

Kernel is compiling cleanly with the cs2005q3.2 toolchain, is there some good 
reason not to use that to compile whole system (IT2006&Maemo2.0 and 
kernel)???

I am also a little bit surprised that this mailing-list does not include more 
people who compiles the kernel by himself/herself (or at least that 
impression I have gotten). Maybe they don't have to ask any questions like I 
have done... :-)

Best Regards,

	Kimmo
