what's wrong with my program

kira · 12-27-2004, 02:30 AM

i written a module by myself,then i complied it with gcc and successed . but when i run the command of insmod the wrong messages showed like that: your kernel dismatch,your kernel is 2.4.20-8 while the module complied with gcc is 2.4.20.
please tell me how to fixed this problem, thinkyou so much.
(the distribution of my linux is redhat 9.0)

I would think, if you program kernel modules you have to compile the kernel source to set your
environment proprely.

Or at least try to upgrade your gcc package

thankyou very much, but i am a newer, could you tell me how to upgrade my gcc package or compile the kernel source on my redhat.
thanks again.

Your problem was not due to gcc package. Its cause your module was compiled with kernel header other than your current running kernel (2.4.20-8). Append (-I/usr/src/linux/inlcude) to gcc (if your current running kernel source code was there).

Hope this help,

thanks, I will try it.

I successed in compilation. but when I try to loading moudle with insmod then the wrong messages showed again like that: you are trying load a module without a GPL compatible license and it has unresloved symbols, the module may be trying to access GPLONLY symbols but the problem is more likely to be a coding or user error. contract the module supplier for assistance, only they can help you.

could you tell me what can I do to solve this problem,thanks again.

Could you try to install a skeleton module? And then insert one by one function to figure out what's cause problem, I think.

Have a nice day,

When insmod my module, the error occured again and messaged that: unsolved symbols sys_call_table.
What's that? and how to fixed,thanks.
