Hi All,

I have a working application in RH6.2 + RTLinux 3.0. I wanted to try
RH7.3+RTLinux3.1 but I am having strange problems loading modules. In
RTL3.1 I get, for example:

 # insmod lp.o
 lp.o: unresolved symbol sprintf

But this is the same source code as my working 6.2 system.

Maybe something was differ with 3.1... so I took my .c file that contained
sprintf and just compiled a simple apps:
http://irtf.ifa.hawaii.edu/~denault/temp/fifo2

This is a simple program just test my sprintf type function. How can my
fifo2 application work, but my real one don't (the file mrt_io.c is the
same in both).

I am using RH7.3, 2.4.18 kernel, contrib/ripoll/rt-patch-2.4.18.tar.bz2

Any hints or secret knowledge about creating modules?

Thanks,

Tony
