LNK1104: cannot open file 'libboost_python27-vc142-mt-x64-1_71.lib' while boost_python version is 1.72


I'm using cmake and Visual Studio 2019 to build my project. My boost version is 1.72 and I generated file libboost_python27-vc142-mt-x64-1_72.lib in directory boost_1_72_0\stage\lib with b2.exe.

I generated .sln file with cmake. Then I build the project in Visual Studio 2019. However, it ended up with an error LNK1104: cannot open file 'libboost_python27-vc142-mt-x64-1_71.lib'

I really can't understand why it asks for libboost_python of version 1_71 instead of 1_72. I never introduced a version 1.71 request in any file. So how should it be like that? And how can I make it work?

Solution

  • I know the reason now. There is another boost directory with some header files in my project folder. I wrongly included the boost directory and made a dependency on boost 1.71....
