CVS2GIT- Conversion: Error "mark ... not declared" when running git fast-import

Question

I'm trying to migrate an old cvs repository to git using cvs2git and git fast-import. The Export seemed to work fine, at least i did not notice any error messages. However, when i try to import the Dump files into my git repository with

git fast-import --export-marks=C:\temp\git-marks.dat < C:\temp\git-dump.dat

i get the following error:

fatal: mark :52 not declared

This is the generated crash report:

fast-import crash report:

So what does mark :52 mean and how can i find out whats wrong about that?

Answer 1

Ok, well my mistake was that i obviously needed to import, not export the previously created marks file :P The following statement seemed to worked perfectly:

git fast-import --import-marks=C:\temp\git-marks.dat < C:\temp\git-dump.dat
