Re: [Boost-users] [python] Linker error when initializing numpy

Hi all, OK, it seems that I have lost some of my boost zen. I remember now that "libboost*.lib" are the static libs and that "boost*.lib" are dynamic variant. I have built both and the linking now works. It seems that linking to static boost libs is not supported on Windows with Visual Studio 2017. Not sure why?

How are you compiling the test progam? Did you set up a test solution? Are you compiling it from command line with cl? Are you trying to use cmake?

Why did you build boost with vcpkg? IIRC, vcpkg/cmake has own conventions; the libraries in the official boost windows distribution do not have 'lib' prefix.

In any case, set up a project in the IDE and adjust linker search paths and libraries to link against (Linker -> Input -> Additional dependencies) in the project properties tab.

Hi all,

I have the latest boost from the master branch and built everything including python. I can see that two python related libs were built:

libboost_python3-vc141-mt-gd-x64-1_66.lib libboost_numpy3-vc141-mt-gd-x64-1_66.lib

For compiling python I use vcpkg and it's generating python3_d.lib for debug and python3.lib for release.

The cpp code I like to compile is:

#include <iostream>

#include #include

namespace p = boost::python; namespace np = boost::python::numpy;

int main() { Py_Initialize(); np::initialize();

return 0; }

A few issues:

1) linker is looking for "boost_python3-vc141-mt-gd-x64-1_66.lib" but I got "libboost_python3-vc141-mt-gd-x64-1_66.lib"

Please tell me how to fix that. For now I just copied the libboost* files and renamed them.

2) Linker error:

"__declspec(dllimport) void __cdecl boost::python::numpy:: initialize(bool)"

How can I resolve that?

Thanks, Christian
