[ltt-dev] Trying to compile lttng-tools

[Bernd Hufmann]

Hi Daniel

The build of LTTng/TMF within the Linux Tools Eclipse Project has been 
fixed. The latest software is now included in the nightly build. 
(http://download.eclipse.org/technology/linuxtools/updates-nightly/).

See also below for answers to your questions.

Best Regards
Bernd

No, UST doesn't work at the moment.

This update site is for signed builds for the indigo release. I'm not 
sure when this update site is actually updated. The fix for the nightly 
build should make sure that the creation of this update site is also 
correct.

Sorry, I'm not familiar with the snapshot feature. I won't be able to 
answer this question.

I use the EGit/JGit plug-ins within my Eclipse environment to checkout 
and import the Eclipse projects. This is pretty quick. However, I don't 
have the firewall issues which you have.

In case you can solve the problem with the firewall, here are the 
instructions to import the LTTng projects to your workspace.
Here are the instructions: After installation of EGit/JGit, you can 
clone the repository from the GIT-repository perspective. Then you will 
see cloned repository "org.eclipse.linuxtools". The expand the tree, you 
will see the "Working Directory" tree item. Expand that too. In there 
you will find the tree item "lttng". Then select "lttng" and press the 
right mouse button. In the context sensitive menu, select "Import 
Project...". A dialog wizard  will open. In the dialog box use "Import 
Existing Projects" and select "lttng" (if necessary). Press next, then 
select all the Eclipse Projects you want to import and the press 
"Finish". That's all.
