Hi Conrad: Just to conclude this thread which I started by mistake on this list, want to say that I was able to isolate the problem. I am using GCC 2.96, and in that for some reasons, if i compile the generated .c/.h files using g++ compiler and then link with other source also compiled with g++ compiler, the linking fails saying that the function in question could not be resolved. instead of that, if i compile the generated .c/.h files with gcc compiler (instead of g++), this problem goes away.
Frankly, I could not find the explanation behind this, and this behaviour is definitely not exhibited in GCC3.2.x series of compiler, i.e. in that case i could successfully compile & link with g++ compiler alone. In future, if I need support, I'd definitely write to the tool vendor for support, i.e. OSS in this case. Thanks for your explanation and response Conrad.
