Error with ReferenceMission2.plx when building about ow_simulator

[kmdalal]

This is an issue for the ow_autonomy repository, but no matter. Your PLEXIL installation is not up-to-date for Release 8. The fix is easy:

cd $PLEXIL_HOME

Make sure you're on the releases/plexil-4 branch (git branch). If not, get on this branch (git checkout releases/plexil-4).

Update the branch (git pull). I suspect some new files will come in.

Rebuild it:

make squeaky-clean
make universalExec plexil-compiler checkpoint

Then retry your ow_autonomy build and the error should be gone!

Sorry, yeah this would have better fit in the ow_autonomy repo. I tried your suggestion but pl the plexil repository is already on the latest version of the releases/plexil-4 branch. I followed the instructions to pull and rebuild it just in case, but I got the same error while building! Maybe there's some more information in the full log, so I've included that as well:

And I got this when making sure I'm on the latest version of Plexil:

laptop:~/plexil$ git fetch; git status
On branch releases/plexil-4
Your branch is up to date with 'origin/releases/plexil-4'.

nothing to commit, working tree clean

[kmdalal]

This is really strange -- the pull/rebuild has always corrected this issue, which several users reported.

Please check what commit your PLEXIL is on.

cd $PLEXIL_HOME
git rev-parse HEAD

The commit hash should begin with df7ed1e020a.

If that's it, you could try the 'make squeaky clean' followed by make universalExec plexil-compiler checkpoint again, in case that was messed up the first time.

If no luck, here's a simple workaround to get you through the build: remove the semicolon after the 'endif' near the bottom of ReferenceMission2.plp. Semicolons are optional after 'endif', but an older version of the PLEXIL compiler disallowed them.

@zainhussaini , is this working for you now? Can this issue be closed?

[zainhussaini]

Yes it's working now, I'm not certain what the issue was but deleting the cloned repos and starting over from scratch fixed it!
