help me please

Welcome to LQ.

The 32bits version of Ubuntu 10.04 should be preferred.
A 64bits OS will will not work with all ns2 functions.

Ns-2.29.3 : ns-allinone-2.29/ must be compiled with gcc-3.4 / g++-3.4.

Synaptic : Settings > Repositories > Other Software :
Tick the three Hardy entries. Then use the 'Refresh' button.
And : You can install 'g++-3.4'.

Start from scratch, with a new unpacked ns-allinone-2.29.3.tar.gz :
cd ns-allinone-2.29/ && export CC=gcc-3.4 CXX=g++-3.4 && ./install
