The command <code>dpkg -s package_name</code> can be used, in the terminal to verify if a package is installed. Replace 'package_name' with the name of the dependency from the above list. | |||
Before installing any missing dependencies, update Raspbian per the above [[Howto:Build_and_run_FlightGear_on_Raspberry_Pi_4#Update_Raspbian|Update Raspbian]] instructions. The below terminal command can be used to install any missing dependencies: | |||
<syntaxhighlight lang="bash"> | |||
sudo apt-get install package_name | |||
</syntaxhighlight> | |||

When using some <code>git</code> commands you might be prompted by <code>git config --global user.email "you@example.com"</code> and or <code>git config --global user.name "Your Name"</code>. In that case a user account is needed at [http://www.github.com www.github.com]. So, before starting the compiling process it would be advisable to first go to their web page and create a free user account. After acquiring the user account, use the below commands (one at a time) in order to satisfy the above <code>git</code> requirement. Replace 'you@example.com' with your <code>git</code> account email address and also replace 'Your Name' with the user name for this account. It might be best to choose a user name without a space in it. | |||
<syntaxhighlight lang="bash"> | |||
git config --global user.email "you@example.com" | |||
git config --global user.name "Your Name" | |||

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 <code>--bare</code>, 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 <code>git fetch foo</code>, where foo is the name of a <s>branch</s>. | |||
Run <code>git branch -r</code> to see what branches are available remotely, then <code>git | |||
fetch foo</code> to retrieve the <s>branch</s> you are interested in (supposedly called | |||
'foo' here). This only happens in the .git subdirectory, but then <code>git | |||
checkout foo</code> 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 <code>git fetch</code> 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. <code>git fetch origin</code> 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 <code>git remove -v</code> from | |||
within your clone, but I believe this info essentially comes from the | |||
.git/config file. | |||

Essential git commands: | |||
* git status | |||
* git checkout | |||
* git pull | |||
** Can be used to update the fgmeta folder when using the download_and_compile.sh script. Use this command from within the fgmeta folder. | |||
* git reset --hard | |||
* git log | |||
