How to set the thread name under red hat linux?

[zhihang_wang]

I have installed the vtune and thread profile on windows. The Linux thread RDC is also installed on my Red Hat Server.

Now I want to use the windows thread profile to monitor the thread of my app. Because there are many threads in my app, I want to rename them.

This is my test to use the libittnotify.so to rename the thread.

#include

#include "/opt/intel/itt/bin/32e/libittnotify.h"

main()

{

_itt_thr_name_set("main", 4);

printf("ok\\n");

}

when I compile it with

gcc test.c /opt/intel/itt/bin/32e/libittnotify.so -o x

There are always errors.

Actually you should call "__itt_thr_name_set("main", 4);" instead of "_itt_thr_name_set("main", 4);" - I verified. Ignore all warnings.
