Transcoder link error when creating a static library

HI guys

I've modified the Transcoder and built it as static library. I've tried to pass it to my C code but I keep getting the error
/home/john/workspace/ipp3g324m/linux/../source/transcoder.cpp:14: undefined reference to `Transcoder::Transcoder()'
/tmp/cc2Cbm6h.o: In function `__tcf_0':
/home/john/workspace/ipp3g324m/linux/../source/transcoder.cpp:14: undefined reference to `Transcoder::~Transcoder()'

I've required include files for the transcoder and the other UMC samples. Could someone please let me know what i've done wrong and what else I may need to change

I've attached the source codes (nothing in them besides creating and instance of the class), Makefile and the error report from the Makefile

Thanks

My mistake didnt include the main :p....but now I cant seem to build the object. I've attached the latest Makefile. I keep getting the error
gcc: ipp_trans.o: No such file or directory

Even though i've mentioned it in the makefile any suggestions?

Hi,

For 'ipptrans.o', I think you need to add '-c' option, if you only want to create the object file, not the application:

ipptrans.o: $(SRCDIR)/transcoder.cpp $(INCDIR)/transcoder_con.h

$(CXX) -c $(CFLAGS2) $(CINCLUDES) $(CDEFINES) $(SRCDIR)/transcoder.cpp

Thanks,
Chao
