C ++ boost nuget无法打开Visual Studio 2015文件

Question

I am making a C++ project (quite new to C++) and it needs the so called "boost" library. I thought I could add it with a nugget to make my life easier...( #include <boost\\date_time.hpp> added) but now I am getting this error

Error LNK1104 cannot open file 'libboost_date_time-vc141-mt-gd-1_65_1.lib'

What is the problem?

Answer 1

Error LNK1104 cannot open file 'libboost_date_time-vc141-mt-gd-1_65_1.lib'

According to the error, you should add the libboost_date_time-vc141-mt-gd-1_65_1.lib library directory to your project configuration. This .lib included in the NuGet package boost_date_time-vc140 or boost_date_time-vc141 .

Since you are using Visual Studio 2015, you just need install the NuGet package boost_date_time-vc140 to your project , NuGet will add the libboost_date_time-vc141-mt-gd-1_65_1.lib library directory to your project configuration automatically. After installation completed, that error will be resolved.

Besides, since you are use boost library in Visual Studio 2015, I suggest that you can use the boost-vc140 , which included many dependencies. So you do not need to add them manually.

Hope this helps.

You need to add the boost library directory to your project configuration, go to the project menu, then properties.

In the property tree go down to 'VC++ Directories' and in the library directories add \\lib64-msvc-12.0 (change the 64 to 32 for 32 bit builds).

I suggest you do this through view->other windows->property manager, then it will be set up for all future projects as well.

The reason why you have a link error is because you installed the header-only NuGet "Boost" package. However, due to an unfortunate design decision, this header-only package also contains header files for Boost libraries that are not header-only, such as datetime. With a better design, you would have gotten the error earlier (at compile time).

The "Boost.vc120" and "Boost.vc140" packages contains both header-only libraries and regular compiled libraries; the difference between them is the compiler used.
