uint64_t not recognized statement.

[soljiang]

When I declare variable as uint64_t, or unsigned __int64, Labwindows gives me error messages when compile.  It says unrecognized statement.  I included stdint.h and userint.h

What is missing?

what is missing:

- what version of CVI are you using?

- do you have the Configuration Option 'Buld with C99 extensions' enabled?

- a code sample

For me, using CVI2013SP1, both

uint64_t test;
unsigned __int64 test2;

is working without error...

I didn't turn on Buld with C99 extensions.  Now seems it solved that particular problem.  Thanks!

I wonder, what if I don't have Buld with C99 extensions enabled?  How can I declare a variable to be an unsigned 64 bit integer?  Thanks.

 unsigned __int64 should work without C99 (since CVI 7); C99 extensions are only needed for uint64

Thank you!
