'NIDAQmx.h': No such file or directory

[cylnu]

Hello, 

I am using an external compiler (gcc) to program NI 6255 on Windows 10. I have  downloaded the NI-DAQmx 17.1.0 Driver Software and started with the available sample codes. When I run a sample code with gcc, it gives me the error ' 'NIDAQmx.h': No such file or directory' since the header filed is included in the program.

As I read in the forum, this header file should be located in <Program Files>\National Instruments\Shared\ExternalCompilerSupport\C\include\NIDAQmx.h . However, inside the Shared directory, there is no 'External Compiler Support'. Therefore, I cannot find the header files.

Can someone tell me what I am missing?

Cheers

Hey cylnu,

I have been looking into this quite a bit, and I think the issue might be in the DAQmx install. Did you make sure to install support for ANSI C when you did the install? If not, make sure you have that installed. This document shows how to modify your installs to include examples:

Follow this, but choose ANSI C under the application development support and make sure it is installed. Then, you should be able to find the header file in the directory that you listed.

Cheers,

Ryan

Hey Ryan, 

Thanks a lot for your reply. I figured it out actually. I have installed NI-DAQmx 17.1. 

The header file is located at

C:\Program Files (x86)\National Instruments\NI-DAQ\DAQmx ANSI C Dev\include\NIDAQmx.h
