Question

我正在尝试在Visual Studio 2013中编译igraph C代码，已经将所有库都包含在属性中，就像igraph C的分布附带的一些示例一样，但我仍然遇到以下问题输出窗口：

1>igraph.lib(prpack.obj) : error LNK2001: unresolved external symbol "public: __thiscall prpack::prpack_base_graph::~prpack_base_graph(void)" (??1prpack_base_graph@prpack@@QAE@XZ)

显然这是与prpack相关的东西，但我不知道我需要包含哪个库，有谁知道如何解决这个问题？

Answer 1

这是igraph的MSVC版本中的错误;尝试将/DPRPACK_IGRAPH_SUPPORT=1添加到编译器选项中，并将PRPACK的源文件从src/文件夹（基本上与prpack _ * .cpp匹配的所有内容）添加到项目中的源文件列表中，然后重新编译。
