That is not the disadvantage. $ git clone |& grep submodules --recursive initialize submodules in the clone The disadvantage is that submodules were not created to be developed in. They are useful for pulling static dependencies that don't update often. For example, they are ideal for KDE 3's "admin" subdir. They can be used for sharing some private libraries between modules (libbtcore between KGet and KTorrent, oxygenhelper between the windeco and the style, etc.). But they are really painful to use if you try to develop inside the submodule while developing on the supermodule as well. Every time you commit in the submodule, the supermodule marks the directory as "changed". So you're always prompted to commit in the supermodule. If you try to change your checked out commit in any way (rebase, switch branches, bisect, etc.), the submodule changes along. So, submodules are good for recreating the KDE modules *at* *release* *time*. That is, when a submodule releases, the supermodule updates. That's the only time they should record the change, or it will get really hairy. That means that when you clone --recursive a KDE module, you get the latest released versions of each submodule. If you wish to move to the development version, you have to cd into the subdirectory and issue the appropriate update commands. -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Senior Product Manager - Nokia, Qt Development Frameworks PGP/GPG: 0x6EF45358; fingerprint: E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358 Qt Developer Days 2010 - Munich Oct 11-13 - San Francisco Nov 1-3 For more information and to register: http://qt.nokia.com/qtdevdays2010
