Re: [linuxtools-dev] UPDATE: Re: OProfile + Linux Tools + CentOS 
Hi Severin
I filed a bug for that issue. It is #353986 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=353986) . 

I do not think that it relates to #336977 since I tried w/ different JVMs .


Many thanks so far
Eric

To solve the error described below

"opcontrol process error output: sudo: sorry, you must have a tty to run

'requiretty' in sudoers file opened by 'install-noconsolehelper.sh' must
be commented out.

FWIW:
I assume consoleholper is available on CentOS. install.sh is intended to
be run on those systems. install-noconsolehelper.sh is for systems with
no consolehelper.


However, then the fun starts again... see screenshot attached (An
internal error occurred during: "Launching op (1)") .

It is not possible to create an OProfile configuration (Profile As>
Profile Configurations)

Various errors are the result.

Does profiling work if you don't go into Profile Configurations? Please
report a bug here:
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Linux%
20Tools&component=OProfile

Please attach the stack trace from the error log (right-click details).

Thanks,

Hi


First, thanks for the reply.

Eclipse Error Log says:

eclipse.buildId=M20110210-1200
java.version=1.6.0_20
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_US
Framework arguments:  -product org.eclipse.epp.package.linuxtools.product
Command-line arguments:  -os linux -ws gtk -arch x86 -product
org.eclipse.epp.package.linuxtools.product


Error
Thu Aug 04 06:45:22 EDT 2011
opcontrol process error output: sudo: sorry, you must have a tty to run sudo

<<<

"opcontrol process error output: sudo: sorry, you must have a tty to run
sudo" seems to be the hint


  Did you verify that oprofile works as expected on the command line?

YES.  I did it like on http://blogs.epfl.ch/article/24223

I also tried with the latest nightly build today>   did not work either


I executed both

- install.sh

- install-noconsolehelper.sh


Many thanks for assistance
Eric

  Hi


  I have troubles starting OProfile (0.9.4 latest Version for CentOS) out
  of Eclipse on CentOS.

  I have tried using CentOS 5.4 + Eclipse Helios 2 SR2 in a virtual
  machine (put in timer interrupt mode like described in [1]).

  Eclipse oprofile hasn't worked very well in a virtual machine and is not
  tested very much. It may work, if the module is manually loaded with
  timer=1 prior profiling from within Eclipse...

  Did you verify that oprofile works as expected on the command line? If
  yes, what sequence of commands did you execute to make it work?


  The error is the following when clicking on "Profile As>    Profile with
  OProfile" in the Eclipse menu:

  "Exit code of opcontrol indicates failure"

  OProfile itself is working and I also executed
  "natives/linux/scripts/install.sh"

  Does this mean that if you use opcontrol in a terminal profiling works
  for you? If yes, what is the sequence of commands you are executing?


  I have also seen some irregularities concerning the unittests of Linux
  Tools 0.8.0 for OProfile support.

  https://hudson.eclipse.org/hudson/job/linuxtools-Indigo/346/testReport/

  Last time I checked all unit tests passed for me locally. I think we
  can't run oprofile tests in the hudson job since it requires root access
  and proper installation of consolehelper/no-consolehelper (for the time
  being). Perhaps I'm wrong :)


  I also tried on a real machine (CentOS 5.6 + Eclipse Indigo) and there I
  get also an error (I think it was the same on - I might deliver the
  message later since I am currently at an other place).

  It should definitely work on a physical machine. Could you try
  installing latest Linux Tools from updates-nightly[1] and try again. If
  oprofile fails, it should give you some hints in the Eclipse error log.


  Well, shouldn't it work out of the box?

  Kind of. If you installed Linux Tools from our update-site, you need to
  set up consolehelper manually. After this step it should work.

  Let us know how it goes.

  Thanks,
  Severin
