I am unsure as to why the undefined reference errors have suddenly popped up; It did not happen until I was working with the code for some time.

What is causing this.

Thanks in advance.

Hi THX 1138,

You need to add "-Mprof=lines" to both the compile and link lines. The problem here is that you forgot to include it on link line, hence the profiling libraries were not included on the link.

Note that you should choose one profile collection method, either instrumented (-Mprof) or sample based (pgcollect), but not both.

I did as you suggested and it still got some linking errors, I will show them now.

I thought your suggestion took care of the problem, but it apparently did not.

Any help appreciated. Thanks in advance.

Now you're missing the PGI Accelerator run time libraries. Add "-ta=nvidia". Rule of thumb is to use the same optimisation flags on both the compile and link lines.
