title: Failing to install omentpp 4.1
body: <p>I am trying to install omnetpp 4.1 (can't install the new version). Anyway, running <code>./configure</code> reports no errors or warnings, but when I run <code>make</code> I get the following:</p>
  
  <pre><code>make MODE=release
  make[1]: Entering directory `/home/yotam/omnetpp-4.1'
  ***** Configuration: MODE=release, TOOLCHAIN_NAME=gcc, LIB_SUFFIX=.so ****

  <p>I am running ununtu 12.10 if it matters. Seems to be code errors, right?</p>
  
  <p>Any suggestions? Thanks</p>
