Python3.6をMinGWでC++に埋め込みました。

Question

python3.6をWin10 64bitシステムのC++に埋め込みます。 Pythonはpython-3.6.1-amd64.exeによってインストールされます。 CMakeList.txtは

cmake_minimum_required(VERSION 3.8) 
project(EmbedPython) 

set(CMAKE_CXX_STANDARD 11) 

set(SOURCE_FILES main.cpp) 
find_package(PythonLibs REQUIRED) 
include_directories(${PYTHON_INCLUDE_DIRS}) 
add_executable(EmbedPython ${SOURCE_FILES} ${PYTHON_INCLUDE_DIRS}) 
target_link_libraries(EmbedPython ${PYTHON_LIBRARIES}) 

の下に表示され、cmakeのは、Pythonパッケージを見つけました。

PYTHON_INCLUDE_DIR C:/Program Files (x86)/Python36/include 
PYTHON_LIBRARY C:/Program Files (x86)/Python36/libs/python36.lib 

Find a comment on githubこれはAPIの問題です。

# used to embed python script 
find_package(PythonLibs 2.7 REQUIRED) # this has to be 2.7 because the 3.0 API requires argv to be wchar_t** rather than the default char** 
include_directories(${PYTHON_INCLUDE_DIRS}) 
target_link_libraries(assignment ${PYTHON_LIBRARIES}) 

以下のエラーは、私が直面してるものです。

プロジェクトを実行するにはどうすればよいかわかりません。

Answer 1

make VERBOSE=1から。

おそらく、問題は32ビットのMinGWと64ビットのPythonを使用しているためです。あなたのpython

の32ビット版をインストールする必要があり、:-)
