libittnotify.lib(ittfortran.obj) linking problem.

Andriy — Fri, 18 Dec 2020 23:44:53 GMT

Hi,

I am using ITT_* API to reduce amount of collected data.

In fact, for now I am using only ITT_RESUME and ITT_PAUSE functions around my critical code.

Everything worked fine while I was working with Advisor 2019 U5.

Now, I've tried Advisor 2020U3 and 2020.1.1 and get the same error at linking stage:

libittnotify.lib(ittfortran.obj) : error LNK2019: unresolved external symbol ___itt_pause_ptr__3_0 referenced in function ITTNOTIFY_mp_ITT_PAUSE

I've checked libittnotify.lib and it only exports corresponding __itt_* functions with two underscores, while ITTNOTIFY_mp_ITT_* subroutines look for functions with three underscores.

For Advisor 2020U3 I use include path as $(ADVISOR_2020_DIR)include\intel64

And library path as $(ADVISOR_2020_DIR)lib64

With libittnotify.lib as additional link dependency.

Am I missing anything in my setup?

Thank you for any suggestions.

1. Windows.

2. use include path as $(ADVISOR_2020_DIR)include\intel64; and library path as $(ADVISOR_2020_DIR)lib64

Eventually, I ended up copying required declarations from `ittnotify.f90` file into my code and commenting out `use ittnotify`.

Examining `ittnotify.f90`, it looks like `ittnotify.mod` was built without defining `intel64` symbol. That explains why it imports three-underscore C functions `___itt_*` instead of correct two-underscore symbols `__itt_*`.

`use ittnotify` still does not work.

Should I just accept that Intel provided module is broken? Or is my build misconfigured?

I could not reproduce the issue as you described, using the latest version of Advisor. Could you please update to the latest version (2021.1) and follow the instructions under the link below for linking the ITT APIs.

https://software.intel.com/content/www/us/en/develop/documentation/advisor-user-guide/top/minimizing-analysis-overhead/collection-controls-to-minimize-analysis-overhead.html

If you are still getting this linker error on a clean setup and using the latest version of the Advisor, please let us know.

Hi Andriy,

As there are no further updates, can I assume that this issue is resolved? If you are still facing the issue after following the latest instructions and the latest tool version, please let me know.

Johny

Hi @Johny_P_Intel ,

I haven't tried the latest Advisor to verify that API has been fixed. Next time I need to analyze my code I will upgrade my installation as per your suggestion.

I am closing this thread based on your response. We will not be monitoring this thread anymore. Please start a new thread if you run into similar issues again with ITT library.
