As I mentioned on my first response to this thread I have been working on trying to make the build system able to install the engine to a directory chosen by the developer, and without root permissions. This is the patch that I prepared for that, please take a look at the commit message: http://gerrit.ovirt.org/10539 The idea is that the developer can chose a directory and then just run the following: ./make.py --build --install --devel --target /that/directory Even the complexity of this command line can be hidden in a make target, or made the default, so the developer will only need to run something like this: make install This will prepare an environment similar to the production environment, with the same directory structure (except the /that/directory prefix) where the engine can run, so to start it the developer only needs to go to that directory and execute the same script that we use in production environments: cd /that/directory/usr/bin ./engine-service start This will also automatically configure the engine for remote debugging (adding ENGINE_DEBUG_ADDRESS=0.0.0.0:8787 to the configuration) so that the developer can connect to the engine with her/his favorite IDE and start debugging immediately. The make.py script also includes options to create Eclipse project files and to configure the Eclipse workspace, which I think is very useful, specially for new developers: ./make.py --eclipse-projects That creates the .project and .classpath files for Eclipse and adds the required variables to the workspace, so after that all what the developer has to do to start working is open Eclipse and import the projects. The patch is not yet ready to merge, as there are a few missing things, like changing the ownership of files when running as root, but I would appreciate if you can test it. -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.
