Hi,
I am trying to get the rt_com running in rt-linux-2.3. I tried to
inert the module but this is what i got:
[root@linuxclient rt_com]# insmod rt_com.o
rt_com.o: unresolved symbol rtl_register_rtldev
rt_com.o: unresolved symbol rtl_unregister_rtldev
I then looked for the "rtl_register_rtldev" string in all the files in
the rt_com directory to trace the problem but looks like that the only
file having this is the rt_com.o module itself.
I did un-rem the NMT RT_Linux CFLAG in the Makefile as per what Jochen
says next, but that didn't work either. It looks like Michael has
already taken care of that in this distribution of the Makefile.
i am nearly running out of educated guesses and am approaching the realm
of un-educated ones now which has been, on occasions, quite disasterous
in the past.
Please let me know what i am doing wrong.
Yours , Emeel.
Sydney, Australia.
P.S. A printout of the results that i am getting is attached.
