我正在尝试安装库 libLAS。我正在使用 Microsoft Visual Studio 2010 、 windows 7 和 Cmake 2.8.10.2 。到目前为止,我已经安装了 Boost 1.51,并遵循了本教程: http ://www.liblas.org/compilation.html#using-visual-studio-9-2008-on-windows
在 cmake 遇到很多问题后,我创建了 .sln,我现在正在尝试编译它。特别是,我正在尝试构建项目“liblas”。我收到 37 个错误,都像这样:
Error 1 error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::generic_category(void)" (?generic_category@system@boost@@YAAEBVerror_category@12@XZ) C:\temp\libLAS\buildout\src\writer.cpp.obj
编辑添加其他错误:
