i am getting following error while compilation of sinewave.c as

#10010 errors encountered during linking; "sine_wave.out" not built    sine_wave             
<a href="file:/D:/ti/ccsv5/tools/compiler/dmed/HTML/10234.html">#10234-D</a>  unresolved symbols remain    sine_wave

why it is so? any other file to be included?? can any one give some solution to this error please

thank you

Hi Abishek,

I will do two things here.  It seems like you need whatever library/support package is necessary for MCBSP.  So I will move this post to the device forum for you.

However, once you find out which includes are missing .... this wiki topic will help give you some ideas of how to add these and correct them so you don't get unresolved symbols.  If you feel you should have all you need, you can use this wiki to just double check everything is in the correct place.

MCBSP_open comes from the CSL.  You will need to add the include path to the compiler options.  You'll need to add the library to the project as well, either through the linker options or by adding the file directly to the project.

i think i have included the files for CSL. what else is missing?

have a look on screen shot.

I don't see a screenshot.  If it's "unresolved symbol" then that's a linker error.  That means you have not correctly added the library to your project.

i have added all required libraries as can be seen in screenshot.shall i re-attach any library? which one?

Here are instructions for attaching images.  None of yours have shown up yet.

sorry for previous mails without snapshots. actually i directly pasted it but it didnt show up.

please look the problem and find me a solution for same

thank you for the reply. it really solved my problem.

one small problem i am having now is to where to look the output??in which graph??

i am using CCS v5.1 and new to DSP processors.

please help me to see the output of program.
