Link error when moving from v3.1 to v3.3

steve gallagher

Hi,

I'm getting a linker error while building a working v3.1 project. I'm using the same IQmathLib.h and IQmath.lib files. It seems to be finding the other IQmath functions so it is finding the lib. Any ideas?

Thanks,

Steve

Forgot to mention that the v3.1 code targeted the F2812 and the new project with v3.3 uses the C6748.

Guess I'd better check for any differences there.

OK, let me try this approach.

What versions of IQmath.lib and IQmathLib.h should I use for a C6748 with CCS3.3?

Thanks

IQmath.lib seems to be the same for both the F2812 and C6748 and IQmath(Lib).h has no significant changes that I can find.

Any TI employees have any thoughts here about why the linker has problems in 3.3 but not 3.1?

Thanks

The IQMath library for C6000 is different than the one for C2000. The one for C6000 can be downloaded here.

An introductory page for C674x that might be additionally helpful: http://processors.wiki.ti.com/index.php?title=C674x/OMAPL1x_Introductory_Information
