Engine compilation fails with "Error 1"

[MirceaKitsune]

I am trying to compile the latest SVN engine, on openSUSE Tumbleweed (via gcc 4.8). Compilation goes well until the end, when the process mysteriously fails for an unexplained reason. The only thing that seems to be printed is the name of the file and something called "Error 1". Anyone else running across this, and knows of a solution? Thanks.
