将FindBoost CMAKE指向boost_python Windows 10，VS 2017 [英] Point FindBoost CMAKE to boost_python Windows 10, VS 2017
问题描述
我的高级目标是安装 BGSlibrary ，这需要在Windows 10上使用Visual增强python Studio2017.我使用cmake 3.9.0从源代码编译了opencv和boost(1.64.0).在BGSLIBRARY的cmake中，我得到了
My high level goal is to install the BGSlibrary which requires boost for python on Windows 10 using Visual Studio 2017. I compiled opencv and boost (1.64.0) from source using cmake 3.9.0. During cmake for BGSLIBRARY I get
$ cmake -DBGS_PYTHON_SUPPORT=ON -DBOOST_ROOT="C:/Program Files/boost_1_64_0/" ..
-- BGSLIBRARY WITH PYTHON SUPPORT: ON
-- OpenCV library status:
-- version: 3.3.0
CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.9/ Modules/FindBoost.cmake:1877 (message):
Unable to find the requested Boost libraries.
Boost version: 1.64.0
Boost include path: C:/Program Files/boost_1_64_0
Could not find the following Boost libraries:
boost_python
No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the
directory containing Boost libraries or BOOST_ROOT to the location of
Boost.
Call Stack (most recent call first):
CMakeLists.txt:75 (find_package)
我在cmake findboost模块上看到了很多问题.好的，让我们从这里开始.
I've seen lots of questions on the cmake findboost module. Okay lets start from here.
- 我下载并提取了boost 1.64.0并将其放在此处
-
我运行bootstrap.bat和.b2来生成构建增强
I ran bootstrap.bat and .b2 to generate the build boost
C:\ Program Files \ boost_1_64_0> b2工具集= msvc-14.1 --with-python --user-config = user-config.jam
C:\Program Files\boost_1_64_0>b2 toolset=msvc-14.1 --with-python --user-config=user-config.jam
使用用户配置
import toolset : using ;
using msvc : 14.1 ;
using python
: 2.7 # Version
: C:\\Python27\\python.exe # Interpreter
: C:\\Python27\\include # inc dir
: C:\\Python27\\libs # link libs
: # conditions
;
我可以在这里看到python源代码
I can see python source here
并可以从Visual Studio 2017命令提示符中确认我在python支持下构建了boost，它成功找到了所有目标.
and can confirm that from within the Visual Studio 2017 command prompt I build boost with python support and it finds all targets successfully.
我可以在这里看到一堆"python" .lib文件.阅读其他问题表明这是它的去向.
I can see a bunch of "python" .lib files here. Reading other questions suggests that is where it goes.
但是我似乎无法接受cmake来查看它. 我尝试将名称libboost_python更改为boost_python.我试过指向cmake -DBOOST_ROOT或-DBOOST_LIBRARYDIR(或非debg，-BOOST_LIBRARYDIR).我尝试将lib目录添加到PATH.但是似乎没有任何作用.这是cmake问题，不完整的Boost安装还是BGSLibrary问题?
But I can't seem to get cmake to see it. I've tried changing the name libboost_python to boost_python. I've tried pointing in cmake -DBOOST_ROOT, or -DBOOST_LIBRARYDIR (or non-debg, -BOOST_LIBRARYDIR). I've tried adding to the lib dir to PATH. But nothing seems to work. Is this a cmake problem, a incomplete boost installation or a problem with BGSLibrary?
编辑
要回答@utopia，有问题的CMakeList部分为
To answer @utopia, the CMakeList section in question reads
if(BGS_PYTHON_SUPPORT)
set(Boost_USE_STATIC_LIBS OFF)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost REQUIRED COMPONENTS python)
find_package(PythonLibs REQUIRED)
message(STATUS "Boost library status:")
message(STATUS " version: ${Boost_VERSION}")
message(STATUS " libraries: ${Boost_LIBRARIES}")
message(STATUS " include path: ${Boost_INCLUDE_DIRS}")
message(STATUS "Python library status:")
message(STATUS " version: ${PYTHON_VERSION}")
message(STATUS " libraries: ${PYTHON_LIBRARIES}")
message(STATUS " include path: ${PYTHON_INCLUDE_DIRS}")
endif()
这是否意味着.lib应该从字面上命名为python.lib?没有其他字符，也可能没有boost_python.lib.具体吗?
Does this mean that the .lib should be literally named python.lib? With no other characters or perhaps boost_python.lib. Is it that specific?
推荐答案
@utopia使我找到了正确的解决方案. .lib必须从字面上命名为boost_python.lib，而不是随Visual Studio编译器版本，boost版本等附加.在此之后，我能够成功构建，不需要cmake标志.
@utopia led me to the right solution. The .lib needs to be literally named boost_python.lib, not appended with the visual studio compiler version, boost version etc. I was able to successfully build after that, no cmake flags needed.
