Joe,
The 4.2 precompiled WPILIB does not have the camera code in it. I duplicated this from the sources in firstforge. First, I checked out the latest sources, created a workbench project from them and did a build. That build had the DriverStationLCD kLineLength symbol problem. I got around this bug by moving the const declaration out of the DriverStationLCD class into the file scope. Then I did a build of the WPILIB again. The result of that build has the problem with the missing AxisCamera that many people are reporting. Thinking that there might be a problem with the make dependencies, I did a clean of the whole WPILIB project and rebuilt the whole thing. The library that resulted from this build does not have the kLineLength problem nor does it have the AxisCamera problem either.

My guess is that the WPILIB that is in the 4.2 release was built after changing only the DriverStationLCD code and the AxisCamera code was left out. Doing a clean build should resolve the problem.
