[Barrelfish-users] [Barrelfish] Missing Makefile rule

[Simon Peter]

Hi Calum,

> I'm currently trying to compile Barrelfish20110301 on ubuntu 11.04 but I get the following error after make has been running for 15mins or so:
> make: *** No rule to make target `x86_64/sbin/splash_barnes', needed by `all'. Stop.

The default build will try to build the SPLASH2 benchmarks, which we 
cannot distribute due to licensing reasons. You can simply remove the 
benchmark from your symbolic_targets.mk file in your build directory.

This is a new type of warning added in GCC 4.6 (you seem to have a 
mislabeled, patched GCC). We compile with -Werror, so it gets turned 
into an error. You should add -Wno-unused-but-set-variable to the 
compiler commandline, e.g. in hake/X86_64.hs.

Hope this helps,
Simon
