Cannot Compile SimpleRobot Example - Missing WPILib.a

[pspeer]

We are also having this problem. From the looks of things, we've followed the same procedure with the same result. We'll keep you posted if we find a solution.

Build Error:
nmppc: 'C:/WindRiver/vxworks-6.3/target/lib/WPILib.a': No such file

I am also having the same issue. I created a similar thread here in the C++ development thread.

We were able to fix this problem.. The simple solution is to find a copy WPILib.a from last season and paste it into the folder "C:\WindRiver\vxworks-6.3\target\lib."

I've attached our WPILib.a file for your convenience.

Good luck.

It looks like the installer is simply missing this file. My guess is we'll be seeing another update once someone discovers this issue. Most teams will be installing from scratch so a large number of teams should encounter this problem if they are following the directions.

Are you sure that last year's WPILib.a works with this years software?

edit: Guess I just better test this Monday

Sorry to hear you're having this issue too... but it's good to know I'm not alone in this!

Thanks a lot for the upload, this may bridge a gap in the immediate short term. However, this is not a long-term solution because...

If you are going to use the CommandBasedRobot, then last year's WPILib will certainly not work since that class was not even present back then - the problem we are currently having will change from "cannot find WPILib.a" to "linker failure - whole bunches of symbols not found". The CommandBasedRobot is but one of a list of changes that have happened in the WPILib since last year. Note: I am basing this last comment on the change-logs on the WPI first-forge page.

Thanks for the feedback, and hopefully WPI releases an update pronto!

Thanks for the info. I wonder if Java has these issues as well; since the languages are the exact same, and the SmartDashboard/Laptop based vision are based on it, maybe it's this year we switch over...

Until the release is fixed, here is the correct WPILib.a that should be in the release to get you through the short term.

Somehow we ended up bad installer. There is a new one posted on FIRSTForge now that has the missing file. Everything else should be the same.

Sorry about the mistake.

This latest update solves this problem Thanks for getting this turned around so fast.

It most certainly will not. The update will be repaired ASAP.
