Can't cross-compiling alsa-driver kernel modules for arm linux

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Sorry for repeated post.
But I'm really confused and any suggestion is appreciated.

I have been trying to cross compile alsa-driver-1.0.22 for my arm-linux
board. After the configuration and make process, there are some *.o
object files generated in the "modules" directory. But the desired *.ko
kernel module files are not generated. When I tried to insert these
object files into the running kernel via insmod command, the insmod
command returns -1 and complains "Invalid module format!".

Here is my configure command:

CC=gcc ./configure --with-cross=arm-linux-
--with-kernel=/work/63/ipcam/Kernel/linux-2.6.19.2-in-use
--with-build=/work/63/ipcam/Kernel/linux-2.6.19.2-in-use
--with-debug=full --enable-dynamic-minors --host=arm-linux
--build=i386-linux --with-redhat=no --with-suse=no
--prefix=/work/63/ipcam/tmp

-------------------------------------------------------------------------------------

From the above outputs, it seems that the configure script can't
determine the correct kernel version of my target kernel, and this will
prevent the "NEW_KBUILD" variable from being defined in Makefile.conf.
Also in Makefile.conf, the "ARCH" variable is not set.



What's the correct way to configure and cross-compile alsa-driver to
generate the desired *.ko kernel modules? Am I missing anything?
