带XG-PON模块的NS3网络模拟器

Question

我是网络领域的新手。我正在开发NS3模拟器，版本3.27。我下载了它，构建了它并运行了示例first.cc、second.cc等(位置: /home/user/ns-allinone-3.27/ns-3.27/examples/tutorial).

现在，我想将XG-PON模块与NS3链接起来。我从sourceforge.net下载了这个模块。并将该文件夹复制到NS3中的"src“文件夹。我尝试使用./build.py --enable-examples --enable-tests命令再次构建模拟器。但是这样做会产生以下错误。

'configure' finished successfully (2.415s)

任何帮助都是非常感谢的。

Waf构建工具抱怨它找不到在xgpon模块的wscript中列出的源文件之一(test/xgpon-pool-allocation-test.cc)。解决方案是从wscript中的可构建测试文件列表中删除该文件，或者找出丢失该文件的原因并将其插入到测试目录中。
