Hi All,

Thanks for the overhelming responses.
I was able to remove the problem of Unknown symbols by linking the proper
libraries. Now the problem got reduced to the following messages.

# insmod brcmstfb.ko
brcmstfb: Unknown symbol printf
brcmstfb: Unknown symbol malloc
brcmstfb: Unknown symbol free
insmod: cannot insert `brcmstfb.ko': Unknown symbol in module (2): No such
file or directory
#

for the above problem i had tried to link "libgcc.a " but those symbols are
also undefined in it also.
RECAP:
While running  the cross compiled directFB example on MIPS chip,*
We tried to install the framebuffer driver(command given above) after
creating the node fb0.
APPROACH:
Actually the code of frambuffer driver consists of usual kernel framebuffer
code and properitiary graphics lib code.
The properitiary graphics lib code is using malloc,print and free from <
stdlib.h> and that is why those symbols are coming undefined.

Could anybody help in this regard?
Thanks in advance.
