<br><font size=2 face="sans-serif">Hi,</font>
<br><font size=2 face="sans-serif"> In 2.6 kernel All the
functions that are being used by a module should have been exported by
the provider..</font>
<br><font size=2 face="sans-serif">For Example If your driver module say
foo.ko wants to use function x ( ) defined in bar.c, then in bar.c
the function x () had be exported using</font>
<br><font size=2 face="sans-serif">EXPORT_SYMBOL_GPL(x); If not when you
try to insmod foo.ko U will get unresolved symbol x.</font>
<br><font size=2 face="sans-serif">There should be something similar in
2.4..</font>

<br><tt><font size=2>Hi all<br>
<br>
For a customised hdlc card we have written hdlc driver.<br>
we need to compile it as a module in linux 2.4.25 version<br>
Thru Config.in we have defined the customised driver as tristate and<br>
selected 'M' in menuconfig for that driver<br>
The other dependencies generic hdlc driver, cisco , framedelay , ppp<br>
etc are compiled as configured within the kernel itself<br>
By giving make modules we have produced driver.o file<br>
<br>
When I insert the driver.o using insmod iam getting the following<br>
unresolved symbols<br>
Even though the dependencies have been configured with the kernel<br>
itself iam getting these unresolved symbols<br>
<br>
If we use modprobe driver.o (or) modprobe driver it is reporting<br>
driver:applet not found..<br>
<br>
Help me to produce a module with its dependencies also to solve the<br>
unresolved symbols error<br>
<br>
<br>
Thanks<br>
<br>
