Linux OPROFILE VERSION

Hello, eveyone ! is there anyone who has used Oprofiled tool ?

I need to use Oprofile  ,a performance monitoring tool on Linux ,in order to speed up my application currently. and I tried many versions Of Oprofiled. and compiled them all successfully , and found that Oprofile 0.9.9 version can produced all oprofiled tools after installing ,such as opcontrol  、opreport and so on. but found that installing Oprofile 1.0.0 version produced these tools lacking opcontrol and oprofied tow tools. then I tried it under both gcc and arm-Linux-gcc conditions and got the same results which  Oprofile 1.0.0 version can't produce opcontrol and oprofied tow tools.

I wonder if it is the Oprofile 1.0.0 version 's disadvantage itself. can anyone explane this phenomenon? I will appreciate it !

    Hi,

    I  need to run Oprofile 1.0.0  on AM437X EVM, and used ti-processor-sdk-linux-am437x-evm-02.00.00.00. I think the

     result that  Oprofile 1.0.0 version can't produce opcontrol and oprofied tow tools but 0.9.9 version does ,has nothing to do with compiler ,it seems because  the Oprofile 1.0.0 itself changed a lot of compared with the 0.9.9 version. but I  have not know how to use 1..0.0 version yet. that is what I guess. does it make sense?

    thanks for your reading.
