Gnuradio Compilation error

Hi,

I get the gnuradio from git and make it.
get the following error.

Could anyone please kindly advice. Thanks!

I’m assuming you are running Ubuntu 11.04?

I addressed this problem in the build guide (
http://gnuradio.org/redmine/wiki/gnuradio/UbuntuInstall):

sudo apt-get -y install libxi-dev

Tom

yes, Ubuntu 11.04

then I ignore the error and make install, and get error on benchmark.py

FYI i had the same error long time ago compiling from git on Ubuntu
10.10
. I recently compiled on Ubuntu 11.04 (both the stable and the git
version) like Tom well knows, my step were :

+sudo apt-get build-dep gnuradio
+install all the dependencies on the gnuradio build guide page ( i got
installed other stuff)
+then the usual steps of building from source

no problems experienced :D. Never ignore the errors when building, at
least you disable the modules…
