Hi All,

I've run into a problem while trying to insmod rtai.o in linux. This
is my configuration:

Redhat Linux 7.3
kernel: 2.4.22-adeos

I've compiled the kernel and reboot fine. However, when i try to
insmod rtai.o, i get the following unresolved symbol:
"/lib/modules/2.4.22-adeos/rtai/rtai.o: unresolved symbol

Does this mean the the kernel was not properly compiled?

Please let me know if you have any suggestions/insights as to how to
resolve this problem.

Thanks in advance,

I have one: subscribe to RTAI mailing list. There is no better place to

even help developers to track problems.


Re: RTAI & LINUX: insmod rtai.o error

1. apply rtai patches to kernel source tree:
 eg. cd /usr/src/linux-2.4.22
 cat /rtaisourcedir/patcher/linux-2.4.22-adeos | patch -p1
 rename your linux-2.4.22 to linux-2.4.22-adeos
2. make config and make sure you have activated
 general > ADEOS support
3. make dep && make bzImage && make modules && make
 modules_install && make install
4. reboot your kernel, make sure you updated lilo, grub or
 what ever bootloder you use
5. clean up the /lib/module/2.4.22-adeos/rtai directory
 change to your rtai source dir and make config
 make dep && make install

mostly this problem is related to wrong kernel configuration or
old modules that depends on other kernel configuration.

Clean up /lib/`uname -r`/rtai directory

Make sure you compile this kernel without the debugging stuff.
at least with my installation i got permanent lock ups.

I myself use 2.4.23-rthal5 with rtai-24.1.13.

Hope that helps
greetings Jean
