hi all, I am using XC164CS board.when i build my source code linker error occurs.How to overcome the following linker error.What is the reason for such error?.The help is not very clear to me.waiting for your reply. Build target 'Target 1' linking... *** ERROR L127: UNRESOLVED EXTERNAL SYMBOL SYMBOL: Convol MODULE: real_T_FFT.obj (REAL_T_FFT) *** ERROR L128: REFERENCE MADE TO UNRESOLVED EXTERNAL SYMBOL: Convol MODULE: real_T_FFT.obj (REAL_T_FFT) ADDRESS: 1BAAH Target not created Thanks in advance Chris
christober, That's a pretty standard error you'll see when you make a mistake writing a program. You've got a variable (or maybe a function) named "Convol" that you've declared as "extern" in the module REAL_T_FFT. The compiler accepts this and compiles that file, but leave it to the linker to find out which OTHER module has the actual definition of that variable. What's happened here is that the linker says that the name "Convol" isn't actually defined in ANY module in your project and so it can't proceed. This could be caused by a typo, by you failing to include a library with your project, etc.
Here's a thread that illustrates what's going on: http://www.8052.com/forum/read.phtml?id=85503 (it's about an 8051, but the principle is exactly the same)
well thanks a lot.Just came to a conclusion that it may be some memory related problem without seeing the help properly.sorry Thanks Neil & daniel Regards Chris
Unless there are other linker / compiler errors that you're not showing us, your conclusion is probably incorrect. This is probably NOT a memory error. If that were the case, you'd see an "ADDRESS SPACE OVERFLOW" error.
