ibstdc++.so.6 need by libFRC_NetworkCommunication.so.1.5.0, not found

Installed Eclipse, Java and the FRC development plugins using the preferred online method by following this document:


I can build the “Arcade Drive” example, but I get this warning:
libstdc++.so.6, needed by C:\Users\myusername/wpilib/cpp/current/lib\libFRC_NetworkCommunication.so.1.5.0, not found (try using -rpath or -rpath-link) Arcade Drive C/C++ Problem

Here is the console build log:

I get the same warning for other projects like “Getting Started”, and “Motor Controller”

I’m running on Windows 7 64 bit.


Does your username have weird punctuation in it? WPI’s software doesn’t work with usernames that aren’t just letters from my experience.

That warning is expected as shown under Build Console on this page: http://wpilib.screenstepslive.com/s/4485/m/13810/l/145320-building-and-downloading-a-robot-project-to-the-roborio

That warning is expected and documented here: https://wpilib.screenstepslive.com/s/4485/m/13810/l/145320-building-and-downloading-a-robot-project-to-the-roborio#BuildConsole

Great, thanks Joe and Ruffles. I do have a . in my user name, but sounds like that doesn’t matter.
