Compiling NIDAQ C codes in DEV C

[CVilla]

It seems you are referencing multiple locations with the NiDAQmx.h file. Your compiler output shows you retrieving it from C:\Dev-Cpp\include instead of from one of the NI directories. The line numbers mentioned do not match the line numbers in my version of NI's header file, so I suspect something is wrong with the version you have in Dev-Cpp.

I suggest the following:

1) Remove any copies of NI files from Dev-Cpp.

2) Reference only 1 of "...\\NI-DAQ\DAQmx ANSI C Dev\..." and "...\Shared\ExternalCompilerSupport\...". They both provide the same resources, so including both areas is duplication. On my Windows system the header and library files were the same.

After that I think the example should compile OK.

No, it did not work either. Below are the errors I got

NIDAQmx.h assumes that __int64 is a built-in type unless __linux__ is defined. MinGW defines __int64 as a typedef in one of the standard headers, not as a built-in type. Try including <stddef.h> (or <stdio.h>) before <NIDAQmx.h>.

Not to hijack someone else's thread, but I ran into the same issue today and Brad's solution worked for me.  I was extending a project by adding another source file, and all of a sudden I was getting this issue with "error: unknown type name uInt64" .  After reading Brad's solution, I realized that I did #include <stdio.h> in my other source files in the previous version that worked, so as soon as I added #include <stdio.h> to my new source file, it built without any issues.

I'm using MinGW on Windows 7.

Thanks.
