topic Hi, in Intel® Integrated Performance Primitives

New requirement on svml_disp.lib?

I'm working on upgrading from IPP 8.1 upd1 to 8.2, and it looks like there is a new dependency on the svml_disp.lib library. Note that I'm linking against the 64-bit static sequential libraries under Windows. What is this new dependency?

Thanks,

Looks like there's also a

Looks like there's also a dependency on libirc.lib. I could have sworn this was a problem which was fixed in a previous IPP release.

Hi,

Using of /NODEFAULTLIB linker option will solve the problem.

Hi Igor,

Using /NODEFAULTLIB leaves me with many undefined symbols during linking. Considering I did not need these two libraries when using IPP 8.1, do you have any idea what changed? Can this requirement be fixed at the IPP level?

Thanks,

Peter

Hi Peter,

yes we will fix the issue in the next IPP versions. And yes - /NODEFAULTLIB requires you to poin all necessary libraries in your linking string. If you have Intel Compiler you can link svml_dispmt.lib or svml_disp.lib library from the compiler "/lib" folder instead of using /NODEFAULTLIB option. If you don't have Intel Compiler I can only recommend you to create empty svml_dispmt.lib or svml_disp.lib library and link it.

Yes, I have the Intel compiler and am using svml_disp.lib and libirc.lib from there, I was just worried about new dependencies. Glad to hear that the next version will remove this dependency.
