[oe] Getting "fatal: Not a git repository"

[Mark Butsch]

Hello,

I am getting the message "fatal: Not a git repository" when I build. It
doesn't seem to be causing a problem, but it bothers me none the less.

---------
[mbutsch at tuxoe 4G]$ bitbake task-base
NOTE: Handling BitBake files: \ (6587/6587) [100 %]

fatal: Not a git repository

OE Build Configuration:
BB_VERSION        = "1.8.13"
METADATA_BRANCH   = "<unknown>"
METADATA_REVISION = "<unknown>"
TARGET_ARCH       = "i686"
TARGET_OS         = "linux"
MACHINE           = "4g-i686"
DISTRO            = "4g"
DISTRO_VERSION    = ".dev-snapshot-20090304"
TARGET_FPU        = ""

I am using an overlay, is that causing this?

Any suggestions on how to solve this?

Thanks,

Mark
