How does this compare to the posix timings?

My next guess is that our LRU cache has some overhead. The files are keyed by paths, so finding correct file handle involves a number of string comparisons. Your extend...

Have you looked at #17, #28, #37? Usually, you get `version GLIBCXX_x.x.x not found` errors when different versions of the standard c++ library are used during compilation and at runtime....

Would b8a4c90 solve this for you?

Can you see the device in `/sys/class/lego-sensor` from command line? (`ls /sys/class/lego-sensor`). If this is the only connected sensor, it should be named `sensor0`. Can you check its `address` and...

This looks like the compiler ran out of memory, which is not unreasonable given the amount of RAM available on the brick. I would try to use a cross-compiler: https://github.com/ddemidov/ev3dev-lang-cpp#cross-compiling...

You can try to precompile the library for them, copy it into the brick (or provide a download link), and let them compile the actual program (and link it to...
