在成功建立Bitbake之后，Yocto抛出一个git Fatal Error“请告诉我你是谁”

Question

After every successful recipe / image build using Bitbake in Yocto, GIT throws out a Fatal Error "Please tell me who you are" (I have attached the detailed output below)

As far as my understanding, this part has only to do with git not being able to commit since it has not been configured and has nothing to do with do_fetch. Am I right?

But i don't wish to use git for my Yocto Projects, therefore don't intend to configure it (neither global nor local), as I am already using SVN.

The part that I don't understand is why does Bitbake (Yocto) throw out this error? How do I get rid of it?

Note: all info such as poky version, host system, architecture is included in the build config.

Any input on how to get rid of this error or could shed some more light on it?

Answer 1

The "buildhistory" feature uses git commits to store the history. git requires a name and email when commiting (because usually the commits are later published).

You can fix the problem by doing what the warning suggests. Run in terminal:

git config --global user.email "you@example.com"
git config --global user.name "Your Name"

Alternatively disable the buildhistory feature in your configuration.

But i don't wish to use git for my Yocto Projects

This isn't really an option: All of the common Yocto layers are stored in git and fetch things from various git repos. Git is practically a requirement and is already working on your system if you got this far -- it's just that fetching does not require an email address and a name.
