I think you should be able to do this in the PREBUILD hook in the DSC file. (Run "git describe" in a script for generating a simple C source file.)


Another option would be to introduce a PCD in your platform package DEC file, with datum type (VOID*) and access method FixedAtBuild. For example:

[PcdsFixedAtBuild]
  gMyPlatformPkgTokenSpaceGuid.PcdBuildIdentifier|""|VOID*|<token>

and when you build your platform DSC, you could pass the following option to the "build" utility:

  --pcd=gMyPlatformPkgTokenSpaceGuid.PcdBuildIdentifier="$(git describe)"

Thanks
