Hello, 

I successfuly installed ns2.34 on a MacOS(Lion). My Mac is a (Core i7-64bit 
processor). When I execute "./validate" and these tests fail: 

validate overall report: some portable tests failed: 
./test-all-newreno ./test-all-sack ./test-all-tcpOptions ./test-all-tcpLinux 
./test-all-tcpHighspeed ./test-all-red ./test-all-cbq ./test-all-webtraf 
some non-portable tests also failed: 
./test-all-srm ./test-all-smac-multihop ./test-all-hier-routing 
./test-all-algo-routing ./test-all-mcast ./test-all-vc ./test-all-session 
./test-all-mixmode ./test-all-webcache ./test-all-mcache ./test-all-plm 
./test-all-wireless-tdma 
to re-run a specific test, cd tcl/test; ./test-all-TEST-NAME 

Do you know what should I do? I read in the official Nsnam Troubleshooting page 
that “ns-2 is known to have problems with some validation tests on certain 
platforms due to 64-bit problems”. I am not sure if theses tests fail because 
of the 64-bit processor but if it's the case is there a solution? 

Thanks in advance for your reply.
