Help needed please: I was using a product from Labjack company. and i downloaded their code and drivers. I found labjackud.h and labjackud.lib. I put labjackud.h in the "include" file and i included in the script. I renamed labjackud.lib into liblabjackud.a and put it into "lib" file. I linked by typing -llabjackud.a in project option-parameter-linker. It still gave me linker errors: [Linker error] undefined reference to `OpenLabJack@20' etc. Can anyone please tell me what i did wrong?? thanks very much....

First, this should probably be in General Programming or For Beginners. Second, what you did wrong was assume that lib files are just like a files with a different extension. There are converters, but they aren't perfect and the header file might use Microsoft specific functionality as well preventing you from using this library with devc++.
