I was compiling some projects of mine, and came around this error. Seems like the AMBuild package needs a little update.

PHP Code:

$ python ../configure.py
Traceback (most recent call last):
  File "../configure.py", line 23, in <module>
    builder.Configure()
  File "c:\mozilla-build\python\ambuild2\frontend\prep.py", line 121, in Configure

The error means you're using an ambuild with an older DB layout than the ambuild you last used to build your project. ambuild does need an update, because you're using an ancient version as the last layout change was October 2015 (i.e. you last build with ambuild later than October 2015 and you currently have a version older than that installed).

Alternatively, your sqlite DB is just screwed, but that seems relatively unlikely. In that case, you would just wipe your build directory and rebuild.

I installed AMBuild on my windows pc about 2 or 3 months ago. It can't be ancient at all. Also, it says my database version is new not old.

I did wipe the build directory, but that did nothing for me.

The example was:
Install ambuild that uses the v4 database layout.
Build your project (generating an sqlite DB along the way).
Install older ambuild that understands <v4.
Try to build your project, but ambuild will complain the DB is too new.

If you really did wipe the build directory and it still says that, then your build environment/ambuild install is totally busted.

For now, I just switched the database to 4 in the script. So far, its been compiling everything I throw at it.
