Introduction

Elphel camera software is based on Yocto Poky distribution, all the individual projects such as Linux kernel drivers, C/C++ applications, web applications, Python projects are organized as Makefile projects, each tied to a separate Git repository. The top project elphel393 has the setup.py script that installs and synchronizes them. All projects have Eclipse IDE configuration data (in eclipse_project_setup subdirectories), and this data is copied to the project root by setup.py. As Eclipse project settings may have user-dependent settings, current configuration files (/.project, /.cproject, ...) are not version controlled, so to restore them after corruption or just to get updated versions you need either to manually copy eclipse_project_setup sub-tree, or delete /.project and re-run setup.py.

Eclipse IDE setting reference not only files that are in the Git repository, but also those that are generated during build process, so Eclipse should be launched with these projects only after the command-line build process has finished. If Eclipse is opened after some project is cleared (such as with bitbake -c clean) it will delete the non-existing directories from .cproject configuration files. If that happens, you may close Eclipse and restore .cproject from the eclipse_project_setup/.cproject.

After running setup.py for the first time you may create the brand new workspace for Eclipse, that should have all necessary plugins (such as CDT and EGit at least) already installed. Workspace is created with setup_eclipse.py script, list of projects that it sets up is saved in setup_eclipse_paths.xml file. setup_eclipse.py provides usage information when launched without parameters, for normall run it requires full path to Eclipse installation (directory that contains eclipse executable and eclipse.ini configuration).
