Hi, I am trying to port G.729 in C6711. But I am getting errors while linking. One such example is as follows, error: symbol _lag multiply defined: c:\program files\hyperception\vabinf\block wizard\m\Encoder.exe\DSPCode\Debug\decoder.obj and c:\program files\hyperception\vabinf\block wizard\m\Encoder.exe\DSPCode\Debug\dfundef.obj If somebody can suggest a way out that will be highly appreciated. Regards, Mithun |

Hello Mithun,
I am not familiar with G.729 and I am not sure what steps you have taken,
but mabe the following will help you.
Since this appears to be a linker error, it looks to me like the symbol
'lag' is defined as a global in decoder.c and dfundef.c.
The likely solution is to either
1. define the symbol only once or
2. change the name of the second definition and all of its relevant
references to something unique like 'lag2'
Start by searching for all occurrences of the symbol 'lag' in
your code. Look at the code and try to determine "are all of the instances
referring to a single lag" [in which case you remove the second definition] or
"are there 2 separate 'lag's being used [in which case you would want
to apply #2 above.

This means that this function is defined in multiple files, specifically decoder.c and dfundef.c. Unlike the Microsoft and gnu linker, the C6x linker does not resolve multiple def- initions. Because of this you have to go into these two files and see where just a prototype is declared (and not the implementation) and add the keyword extern in front of it.
