arm-bcm2708-linux-gnueabi-gcc: Syntax error: word unexpected (expecting ")")

[TKR-US]

Hello,

I search to compile my own kernel 3.6.11 because i've a problem with ax88179_178a driver (i can compile it, install it, but he said in syslog "disagrees about version of symbol module_layout", and modprobe said "ERROR: could not insert 'ax88179_178a': Exec format error")

So, i use http://elinux.org/RPi_Kernel_Compilation method (after trying lot of methods, since.... one week now :( ):
cd /usr/src
git init
git fetch git://github.com/raspberrypi/linux.git rpi-3.6.y:refs/remotes/origin/rpi-3.6.y
mkdir linux && cd linux/
git checkout rpi-3.6.y
cd ..
git clone git://github.com/raspberrypi/tools.git

export KERNEL_SRC=/usr/src/linux
export CCPREFIX=/usr/src/tools/arm-bcm2708/arm-bcm2708-linux-gnueabi/bin/arm-bcm2708-linux-gnueabi-

cd /usr/src/linux

make mrproper
gzip -dc /proc/config.gz > .config
ARCH=arm CROSS_COMPILE=${CCPREFIX} make oldconfig
ARCH=arm CROSS_COMPILE=${CCPREFIX} make menuconfig
ARCH=arm CROSS_COMPILE=${CCPREFIX} make

have you an idea?

gzip -dc /proc/config.gz > .config

Are you doing this on the Pi or on the build machine? If you do it on the build machine, you get the wrong config.

This will give you the default config used in the Raspian kernel:
ARCH=arm CROSS_COMPILE=${CCPREFIX} make bcmrpi_defconfig

I did a build with bcmrpi_defconfig on rpi-3.6.y yesterday, and it worked fine for me.

@BzH35 From here it looks like you're trying to compile the kernel on the pi using the instructions for crosscompilation. In that case you don't need to crosscompile anything, see http://elinux.org/RPi_Kernel_Compilation#1._On_the_RPi

If not then I'd still recommend not to use /usr/src/ as your base directory. Depending on your setup, your distro's kernel sources might mix up with the Pi's sources.

I'm doing it on the PI, i've some problem with qemu to launch my img (i look this problem later)

i use /usr/src as base directory :)

I'm going to try the compilation with 3.2.0-4- rpi because i make an successful install ax88179 driver

i'll come back later :)

@notro

if you compil on raspberry, can you tell me how do you do it?

make mrproper
gzip -dc /proc/config.gz > .config
make oldconfig
make menuconfig
make (or debian method (but i've error with this method), make-kpkg kernel_image modules_image and after? dpkg -i deb ? i've no problem under debian with intel or amd, but with raspberry......)

?
or another method ?

[notro]

This is how I do it on the Pi

# I'm working in the home dir
cd

# shallow clone to speed up download, git pull won't work when done like this
git clone --depth 1 git://github.com/raspberrypi/linux.git

cd linux/

# not really necessary as the repo hasn't been touched
make mrproper

# default config as is used in the Raspian image
make bcmrpi_defconfig

# or if you run a custom kernel which config you want to use
zcat /proc/config.gz > .config

# config changes
make menuconfig

# this takes 8-9 hours
make

# install kernel and modules
sudo make modules_install
sudo cp arch/arm/boot/zImage /boot/kernel.img

@notro

3.2.0-4 compilation and installation works fine, thanks a lot!!!

[jiapei100]

I followed notro with the newest kernel 3.14.
But after rebooting RPI, uname -r still gives me
$ uname -r
3.12.20+

Why is it so?

Cheers
Pei

Have you replaced /boot/kernel.img?

You can check the version of an uncompressed kernel like this:

$ strings arch/arm/boot/Image | grep "Linux version"
Linux version 3.14.3 (pi@raspi2) (gcc version 4.7.1 20120402 (prerelease) (crosstool-NG 1.15.2) ) #1 Wed May 28 14:28:14 CEST 2014

Running kernel:

$ cat /proc/version
Linux version 3.10.25+ (dc4@dc4-arm-01) (gcc version 4.7.2 20120731 (prerelease) (crosstool-NG linaro-1.13.1+bzr2458 - Linaro GCC 2012.08) ) #622 PREEMPT Fri Jan 3 18:41:00 GMT 2014

zImage is a compressed version of Image. It unpacks itself before booting:

Uncompressing Linux... done, booting the kernel.

It doens't matter which one you copy to /boot/kernel.img.
