Unity build fails

[dstaubsauger]

As the title says, unity fails to build for me. This is the error. (if you need the english translation of the error, how can i change the language?)

Could you please provide more information?

Probably there are other build-failures happening prior to this one.

set your environment-variable LANG to LANG=C. That's all.
