To everybody having problems with the build:
Subversion and TortoiseSVN changed their repository format as of version 1.4. This means that if you do not use the svn client (which you really should), the entries file could not be parsed by autorevision any more (see Seth's post yesterday).
Parsing the entries file was a fallback solution all the time anyway, the pristine way of doing things was to have the svn client installed.
The present version of autorevision is (hopefully) compatible with the new 1.4 format. This also means that it is no longer compatible with the 1.1-1.3 format (which was a non-wellformed xml file before). Sadly, instead of fixing the non-wellformed xml document, they replaced it with some binary representation. With the xml document, autorevision could do a "gentle failure". Since there is no structure in the document other than a few line breaks now, this is kind of complicated...
To be honest, I don't know how far compatibility goes, since the entries file format is kind of an undocumented, proprietary thing, but it looks easy enough, and I am relatively sure it works OK.
The information we need seems to be in lines 2 and 5 of the file (unless they change it again in the next version). I have verified that in about two dozen folders belonging to half a dozen working copies.
To make it work:
1. you need to run update using the new version, so the entries file is updated.
2. if you have broken the generated header due to using the updated autorevision with svn 1.3, you need to delete the generated header (sdk/autorevision.h) before proceeding, as it will otherwise not be updated.
3. proceed as normal
