Nangan Chen,

Please take a look at this link, it is the same as your issue. Please check if the solution suggested there (i.e. linking to IQMath.lib) in your project solves the issue.

Good to hear that it works.

The warnings occur because of a mismatch between the compiler in use, and the compiler that was used to create the IQmath library. They are harmless.

Please mark issue as resolved.

Thanks,
Sira

Try to install v6.2.7 and compare build results.
