[linuxtools-dev] UPDATE: Re: OProfile + Linux Tools + CentOS
|
Hi
To solve the error described below
"opcontrol process error output: sudo: sorry, you must have a tty to
run sudo"
'requiretty' in sudoers file opened by 'install-noconsolehelper.sh'
must be commented out.
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.
Many thanks for any contributions
Eric

Hi
First, thanks for the reply.
Eclipse Error Log says:
>>>

java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_US

Command-line arguments: -os linux -ws gtk -arch x86 -product

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
