Unresolved symbols

Hello all,

I have tried to use the drivers and have gotten everything to compile.
I followed the posted instruction and then........
I then make "rmmod" and make "insmod" and after the "make insmod" I look at dmesg|more
It is filled with unresolved symbols. I have tried rebooting (at nauseam) and no change.
I have upgraded the kernel and done all the steps all over again with the same results.
If someone wants to look at about 5 screen fulls of unresolved symbols I can post the relevant parts of dmesg.

IF any one has any suggestions I will try them and report the results.

Later,
Jonathan

You should check:

1) that you're compiling against the same linux headers of the linux kernel you're using.

Use uname -a to get the linux kernel in use, and verify that the headers used during compilation are the correct ones. On a Debian/Ubuntu based system for each pre-compiled linux-image package there is a corresponding linux-headers package, eventually install it.

2) that you don't have a conflict with some already installed module. For example I experienced this when installing the v4l-dvb modules which conflicted with the old standalone gspca module (gspca V1). Since you can't have both installed you have either to remove the old module and reinstall the v4l-dvb modules either to remove the v4l-dvb modules and reinstall the old standalone module.

Unfortunately I think there isn't a make uninstall rule, so I think the only solution to revert a system is to reinstall the kernel (easily done with a package management).

HTH, regards.
