Hi Leonardo, you should have provided a little more information than this, like what is your gr version (there are *many* of them out there) and which compiler are you using? Best regards, Dimitri On Mon, 12 Nov 2012 20:28:42 +0100, Leonardo Lazzaro < lazzaroleonardo(a)gmail.com&gt; wrote: Hi!

Now this is strange, using gr v3.6.2-112-gfa4f1c2f here myself. Others have confirmed it builds fine on recent Ubuntu as well (didn't try that myself). Can you check if there are any leftovers from the package version of gr and then delete build directory & retry from scratch?
