1、关于 ns-2.35 安装之后 validate 时验证结果不能通过的问题完成 ns-2.35 的安装的安装之后，执行 ./validate，结果如下：validate overall report: some tests failed:./test-all-newreno ./test-all-tcpOptions ./test-all-tcpVariants ./test-all-aimd ./test-all-frto ./test-all-quickstart ./test-all-manual-routing ./test-all-linksto re-run a specific
2、test, cd tcl/test; ./test-all-TEST-NAME中间还出现过 Test output differs from reference output 的情况，在 Kali 和 Ubuntu12.04 下都试过。最后做了两项工作，结果貌似正确了。一是 gcc 的版本问题在终端输入 gcc -v，查看 gcc 的版本，很多系统是 4.6 或者 4.7，降到 4.4 的版本。下面的内容来源于帖子http:/ GCC 4.41.apt-get install gcc-4.4 g+-4.4 g+-4.4-multilib gcc-4.4-multilib /First, ins
