For this lab, we have the great difficulty to get this package compiled. This lab package is provided by the link sent from Joe.

Will that be possible for someone to send me your compiled package: lab8_localization?

Any suggestions and help will be greatly appreciated.

Thanks
Jimmy

Without compiling to be sure, we’d guess that there’s a syntax error in your code above line 84 (and you may be reading the compiler output from the bottom up instead of from the top down?)

Can you post the entire compiler output?
