Hi,
Having got eclipse installed and working and oprofiler running from the command line, I've been trying to install the plugin.
(I think) I've followed the instructions in http://wiki.eclipse.org/Linux_Tools_Project/OProfile/User_Gu ide, including building opxml and installing it as it wasn't on my system at all.
When I try to profile c++ in Eclipse I get the error: "An error occurred with opxml The xml output could not be read..."
Running opxml info gives:
"oprofile: could not open unit mask description file /usr/local/share/oprofile//x64-64/hammer/unit masks"
and indeed there is no oprofile directory in /usr/local/share.
Any ideas how to proceed? What have I missed?

There should be an oprofile directory created in /usr/local/share by default after running make install. You could try looking on your system if by any chance it may be somewhere else, but if you did just a basic ./configure, without adding any flags like --prefix, or --datadir then there's no reason for it to be anywhere else. In fact, I think that even if you did, oprofile should use the values you specified when searching.
Also, after starting opcontrol, executing your binary, then stopping it, does running 'opxml sessions' show a session named "current" under some event name in the xml. If so, then does running opxml model-data [event_name] [session_name] output xml data on that session?

Yes, opxml sessions gives a session called 'current'
Running opxml model-data CPU_CLK_UNHALTED current gives a seg fault.

After manually building opxml, I also encountered a segfault.
Used system: gentoo linux on amd64, using binutils-2.20.1-r1.
Root cause is that a sample for " /var/cache/fontconfig/3830d5c3ddfd5cd38a049b759396e72e-le64. cache-3 " is attempted to be examined. opxml seemingly doesn't handle errors properly here.
opxml of org.eclipse.linuxtools-0.20 crashes on "opxml model-data CPU_CLK_UNHALTED current"
with a running oprofile daemon instance.

An update on my attempts to get the plugin working:
Upgraded Ubuntu to 10.10. This stopped the existing Eclipse installation working completely (no default text editor, compile & run did absolutely nothing). Seems it couldn't find the CDT (which I'd had to reinstall as 10.10 had removed it).
Anyway, removed the eclipse installation. Downloaded the Helios version and manually installed it. Likewise with Oprofile. Eclipse works again.
Oprofile gave an error about a missing qt library. I have both qt3 and qt4 installed. Qt4 definitely works. Don't have anything to test qt3.
Tried installing the plugin using http://wiki.eclipse.org/Linux_Tools_Project/PluginInstallHel p. It gave the following errors:
An error occurred while collecting items to be installed
session context was:(profile=epp.package.cpp, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

I tried the suggestions here: http://stackoverflow.com/questions/511367/error-when-updatin g-eclipse
No luck. Still the same error.
The wiki at http://wiki.eclipse.org/Linux_Tools_Project/PluginInstallHel p talks about manually installing 'zip' files. But there doesn't seem to be a zip file, only bz2 files and the repository archive dialog will only accept .zip or .jar.
I also tried extracting the bz2 file to the eclipse directory but it's not recognized. I wasn't sure exactly which directory it should be in (plugin, top level, other). I'm not sure if manual installation is even allowed although some websites e.g. http://agile.csc.ncsu.edu/SEMaterials/tutorials/install_plug in/index_v35.html suggest it is (but then miss out important details).
There seem to be a _lot_ of reports of errors when installing the plugin so should I just wait (another) few months or is there anything I can do to get it working now?
Thanks,
Rob.

This is a known Ubuntu/Debian bug. There is a work-around for this, but I don't recall what it was. Could you drop by #eclipse-linux on irc.freenode.net (IRC). There are usually Ubuntu/Debian maintainers for Eclipse around. They would be happy to help you. Sorry about that.

There is an EPP package which includes CDT, Linuxtools (i.e. also the oprofile plug-in). It's available here:
http://www.eclipse.org/downloads/
The package you are looking for is called "Eclipse IDE for C/C++ Linux Developers". Could you try using that? When you try to use the oprofile plugin the first time you will need to compile opxml first, but instructions for that should pop up once the plugin notices that there is no opxml where it looks for it. Feel free to get back to us should you have problems compiling that. Either here or in #eclipse-linux on Freenode.
Cheers,
Severin
