C++ gcc链接器和OGDF“；未定义对`ogdf:：Initialization:：Initialization（）'&引用；

我正在努力工作，看看它是否适合我的项目，但我有一个样本程序的问题

我正在尝试编译：

但是我得到了以下错误

/tmp/ccbpkfdt.o: In function `main':
test2.cpp:(.text+0x12): undefined reference to `ogdf::Graph::Graph()'
test2.cpp:(.text+0x2e): undefined reference to `ogdf::randomSimpleGraph(ogdf::Graph&, int, int)'

我尝试编译hello world，其中包含来自OGDF的内容，但我仍然得到：

undefined reference to `ogdf::Initialization::Initialization()'

---

我认为我没有正确链接或其他什么？

当使用OGDF作为共享库时，必须使用-DOGDF_DLL构建程序

---

请参见此处：

在与库链接时，您必须非常小心键入内容的顺序。 尝试将

test2.cpp

放在

-lOGDF

之前，如下所示：

g++ -pthread -I ./OGDF/ -L ./OGDF/_release/ test2.cpp -lOGDF

你让它工作了吗？我添加了一个解决方案。试试看：）

undefined reference to `ogdf::Initialization::Initialization()'

g++ -pthread -I ./OGDF/ -L ./OGDF/_release/ test2.cpp -lOGDF
