[eclipseoprofile-devel] Does not work as expected

[<ae...@we...>]

Hi,

I am trying to get the plugin working under Gentoo with Eclipse 3.2.1, CDT 3.1.1, Sun JRE 1.5. In principle, the plugin works but I cannot profile anything :(

1. I setup opcontrol to work with sudo. I changed the opcontrol wrapper script (somewhere in eclipse/plugins/oprofile.core.linux) to use sudo (there is no consolehelper app in Gentoo):
exec sudo /usr/bin/opcontrol ${1+"$@"}

This works perfectly if I start this script from a console (e.g. opcontrol --reset).

However,  I cannot change any parameters from within the launch configuration in Eclipse. The configuration shows me the correct Counters but if a change any parameter it does not affect oprofile (opcontrol --status does not show anything different).

I put the opcontrol wrapper script in the $PATH but it seems not to be called. What I am doing wrong?



2. I parametrized then oprofile manually from the console and started profiling an application within Eclipse (start/stop as well dump works well).
I open then the System Profile and Sample View in Eclipse to have a look at the profiler data. The results look reasonable at first glance. The counted samples are exactly as shown by the command 
opreport image:APPLICATION -l
but the wrong functions are shown !! The same holds then if I dive deeper into the functions to examine the source code lines. Any hints?

Yeah, I think the best we've got is at
http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/org.eclipse.cdt-contrib/org.eclipse.cdt.oprofile-home/developer/info.html?cvsroot=Tools_Project

Sorry about the sad state of documentation.  I really need to post some
more information about this stuff.

You should be invoking the build as a Java runtime process; you don't
invoke the build directly with a Java compiler.  The following build
command uses your standard Java runtime to launch the Eclipse plug-in
builder.  The plug-in builder uses the internal ecj installation that
comes with the Eclipse distribution that you have installed at
ECLIPSE_HOME.  So behind the scenes, you're actually building the
plug-ins with ecj, but you need to start the build process in a plain
old Java runtime environment.

$ cd /path/to/org.eclipse.cdt.oprofile.releng
$ export ECLIPSE_HOME=/path/to/eclipse/dir
$ java -cp $ECLIPSE_HOME/startup.jar \
	org.eclipse.core.launcher.Main \
	-application org.eclipse.ant.core.antRunner \
	-DbaseLocation=$ECLIPSE_HOME \
	-Dpde.build.scripts=$ECLIPSE_HOME/plugins/org.eclipse.pde.build_3.1.0/scripts \
	-Dconfigs=linux,gtk,x86


Hope that helps.  Let me know if you have problems - hopefully I can
have a look at this on the weekend.  My Eclipse build hacking skills are
a little rusty right now.

Hi Mariano,

Eclipse-OProfile is really just a front-end on top of the OProfile
profiling tool [1].  OProfile is a Linux-only tool, so Eclipse-OProfile is
really only useful on a Linux system.  If you're looking for a profiling
tool for Windows applications, then Eclipse-OProfile (nor OProfile) won't
work for you.

It may be possible in the future to use Eclipse-OProfile on a Windows
machine that acts as a front-end to OProfile on a remote Linux system, but
this isn't currently supported.

Thanks for your interest,

Jeremy
