Rebuilding the WPILib?

Install a Subversion client such as SlikSVN.

You can either live with it or you can edit the compiler settings for the project to remove the call. That is how we automatically read the current SVN revision and build it into the library. If you are not using the SVN repo (instead using the packaged source) then this is your only option. If you are using the SVN server at FIRST Forge, then you just need to install SlikSVN.

I am using the packaged source because of this statement on the WPILib FAQ's on FirstForge:

The source code on the SVN server does not include the source for the same revision that was released in an update. What's wrong?

This is just because we're not as fast at merging the source code to the public SVN repository. Check back soon and it should be up to date

I can't find where to turn off the SVN sync. I am looking in "Project->Properties->Build Properties" mostly (as well as the other items in Project->Properties) but I cannot find anything that says "repository" or svn or anything like that. Can you point me to the option? Thanks again for you help.

In Project Properties->Build Properties->Build Tools tab->Build Tool: C++-Compiler->Build spec specific settings->Command: you need to remove the following text:

-D'SVN_REV="$(shell svnversion -n ..)"'

That is not a statement of fact. It is a FAQ. Sorry if that's misleading. It's saying that if you discover that the SVN source is not up to date at some point, you have other options. It is up to date right now.

Instead of removing the text you mentioned completely I changed it to:

-D'SVN_REV="UNCONTROLLED"'

This is to avoid a compilation error because SVN_REV needs to be defined. Regarding the svn repository, this repository only gets updated each time a release is made. It is not a development repository, correct?

Sounds good.

Correct. This is the public repository that is synced to the development repository when a release is made. This allows teams to see the history of the library, create patches against specific revisions, blame a developer for a bug, and look at revision comments for specific changes.
