igraph C在Visual Studio中编译链接错误 [英] igraph C compiling link errors in Visual Studio

问题描述

我正在尝试在Visual Studio 2013中编译igraph C代码，已经将所有库包含在属性中，就像igraph C发行版附带的一些示例一样，但是在输出窗口:

I'm trying to compile an igraph C code in the Visual Studio 2013, already got all libraries included in the properties, just as some examples that come with the distribution of igraph C, but i still got the following problems in the output window:

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)
1>igraph.lib(prpack.obj) : error LNK2001: unresolved external symbol "public: __thiscall prpack::prpack_igraph_graph::prpack_igraph_graph(struct igraph_s const *,struct igraph_vector_t const *,int)" (??0prpack_igraph_graph@prpack@@QAE@PBUigraph_s@@PBUigraph_vector_t@@H@Z)

很明显，这与prpack有关，但是我不知道我需要包括哪个库，有人知道如何解决这个问题吗?

Obviously it's something related to the prpack, but i have no clue of which library do i need to include, does anyone knows how to solve this?

推荐答案

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，然后还将src/文件夹中的PRPACK的源文件(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.

This is a bug in the MSVC release of igraph; try adding /DPRPACK_IGRAPH_SUPPORT=1 to the compiler options and also add PRPACK's source files from the src/ folder (basically everything that matches prpack_*.cpp) to the list of source files in the project, then recompile.
