Gcov .c annotation failure [message #1403023] Sun, 20 July 2014 01:53 Go to next message

I just learned of the Linux Tools project. I downloaded the 64-bit Eclipse Luna 4.4.0 CDT version on a 64-bit Scientific Linux box. I added --coverage to the compile and link lines and was immediately able to generate and see the coverage report and line highlighting for the created-by-eclipse "hello world" C++ project.

When I tried the same procedure with the created-by-eclipse "hello world" C project, I could get the coverage report view, but when I click on the c-file from the report, I get an error:

Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".
java.lang.ArrayIndexOutOfBoundsException: 3

...etc.

I tried in a new workspace with the same results. Is it something I'm doing? Since this is an unadulterated new installation using the eclipse, new "hello world" C-project, I can't see what I might have introduced into the process. I'm left wondering if there is something missing on my Linux box, but it is working for the C++ project.

Any ideas?

Hi Jeff,

This is a bug in the Gcov Integration plugin that was fixed a little while ago and should be present in our nightly builds.
Could you try adding the Nightly Builds site (http://download.eclipse.org/linuxtools/updates-nightly) to your list of available software repositories, and then try updating just the Gcov Integration plugin. That should resolve the issue.

Thanks, Roland,

Whatever the team did fixed it. I was able to seamlessly update and it immediately worked.
