I'm not knowledgeable about details of the RaspBerry PI build; what I can | |||
say regarding your message is: when you clone a Git repository with no | |||
special option such as --bare, some branch is initially checked out (often, | |||
this is 'master'). This means that only this particular branch is clearly | |||
visible in the directory where the repository has been cloned. Other | |||
branches may be present in hidden/machine form inside the .git subdirectory | |||
after you do 'git fetch foo', where foo is the name of a <s>branch</s>. | |||
Run 'git branch -r' to see what branches are available remotely, then 'git | |||
fetch foo' to retrieve the <s>branch</s> you are interested in (supposedly called | |||
'foo' here). This only happens in the .git subdirectory, but then 'git | |||
checkout foo' should cause this branch to appear in the filesystem, | |||
replacing whatever was previously checked out in your clone of the upstream | |||
repository. In the case of the download_and_compile.sh script, | |||
OpenSceneGraph-3.4 is the name of the OSG branch currently used by the | |||
script (until a newer version is deemed preferable). Note that as a safety | |||
measure, you can't check out a different branch when there is “unfinished | |||
work” (things modified but not committed) on the currently checked-out | |||
branch. | |||
Hope this helps. Regards | |||
I have to correct something from my first reply in this thread: | |||
The argument passed to 'git fetch' is not branch name (according to | |||
the manual, it's a <refspec>). The way I use this command is by | |||
passing a remote name, e.g. 'git fetch origin' or 'git fetch | |||
upstream'. A “remote” is some place where the repository is hosted | |||
that is known to your clone (.git/config). Thus, your clone can fetch | |||
branches and commits from remotes. A remote can offer many branches. | |||
You can display info about known remotes with 'git remove -v' from | |||
within your clone, but I believe this info essentially comes from the | |||
.git/config file. | |||
