well in the german forum they told me i forgot the z in tar -xvf
that was right but even now i still have the same error
and it doesnt seem sfml would install
entering directory
leaving directory
is all that it says when i type sudo make install
inside of the sfml directory
other archives do run
_______________
only one thing tar -xvfz tells that i doesnt know the opztion -z
so i diod it manually by using gzip -d
