cross compile error with new tarball

[James Ham]

Hello,

I'm trying to cross-compile from debian lenny (2.6.24-1-486) to an arcom viper (arm) using 2.6.11.11-arcom3. I run config as follows:

make config CROSS_COMPILE=arm-linux-

then

make

All goes well until make switches to the linux source tree:

make[3]: Entering directory `/usr/src/linux-source-2.6.11.11-arcom3'
CC [M] /usr/src/linux-wlan-ng-0.2.9/src/p80211/p80211mod.o
cc1: error: invalid option `preferred-stack-boundary=2'

make[1]: *** [all] Error 2
make[1]: Leaving directory `/usr/src/linux-wlan-ng-0.2.9/src'
make: *** [all] Error 2

I've made a kernel for the target arm machine in this tree, so some of it works at least.

The cross compiler "arm-linux-gcc" is version 3.4.4

I've attached "config.in" and "config.out". Any ideas?

Regards,

make config CROSS_COMPILE=arm-linux-

linux-wlan-ng picks up the the build configuration that the kernel is
using. The above isn't all you'd need to build the kernel; you also
need an ARCH= value, like this:

CROSS_COMPILE=arm-linux ARCH=arm make config

I did a "make distclean", then

CROSS_COMPILE=arm-linux- ARCH=arm make config

then "make".

This changes the error, but it still doesn't complete:

Any help you can give me is greatly appreciated.

Hello Solomon,

I've gotten a lot farther, but still no joy.

Google is my friend :-) I found a reference that a line in the arm
Makefile needed to be changed as follows:

PLATFORM_CPPFLAGS + = $ (call cc-option,-mapcs-32,-mabi = apcs-gnu)
改成： With:
PLATFORM_CPPFLAGS +=$(call cc-option,-mapcs-32,$(call
cc-option,-mabi=apcs-gnu),) PLATFORM_CPPFLAGS + = $ (call
cc-option,-mapcs-32, $ (call cc-option,-mabi = apcs-gnu),)
再make,就OK了。

Then I discover that ARCH needs to be in the environment, but
CROSS_COMPILE needs to be an argument to "make config". so

export ARCH=arm
make config CROSS_COMPILE=arm-linux-

works. BUT something had tampered with my linux source tree so I was
getting lots of errors when wlan tried to compile modules. So I did a
"make distclean" on the tree and made the kernel _again_.

Then back to the wlan source tree, another make distclean, make config
and make. This got me to the point below.

Googling gfp_t, it appears that this type did not appear until kernel
2.6.14, and I'm cross-compiling to 2.6.11. Again, any suggestions?

Jim Ham

Hello Solomon,

I guess I'm just impatient, but I added the following to the top of
hfa384x_usb.c just under all the includes:

#ifndef gfp_t
#define gfp_t int
#endif

Now the tree makes successfully.

Regards,

Jim

Hello,

I've applied the patches from Pavel. The project now makes without
errors and I can load the modules on the target also without errors.

Great!

Jim
