Hi, I'm using VisualDSP++ 2.0 (ADSP-218x). When I compile I get the following warning: "C:\Program Files\Analog Devices\VisualDSP\218x\include\signal.h", line 97: remark #193-D: zero used for undefined preprocessing identifier #if __cplusplus ^ How do I cause "__cplusplus" to be defined? |

Looks like a bug in the header file. __cplusplus is defined by all C++ compilers, and not defined by C compilers. For dual-mode compilers, they either define it or not based on which mode you've requested. (For SHARC, this is done with the command line option -c++.) My guess is that the line should read "#ifdef __cplusplus". You should see if ADI has an update (possibly unannounced) which fixes this. |

Are you saving your file as .cpp instead of just .c ? Also, check any ide options. wrote: > > Hi, > > I'm using VisualDSP++ 2.0 (ADSP-218x).
