我正在尝试使用swig在python中使用共享库。我对c ++的实验不是很充分，但是我已经用一个简单的对象（在c ++中）进行了第一次测试，并且效果很好。
现在，我尝试使其与已经在Linux（和Windows）下编译的更大项目一起使用。但是我不能使它工作。
这是我尝试过的：
我的Swig CMakeLists：
project(elecswig)
include_directories(${COREALPI_DIR}/include)
include_directories(/usr/include/c++/4.9)
find_package(SWIG REQUIRED)
include(${SWIG_USE_FILE})
if (NOT MSVC)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
endif()
find_package(PythonLibs)
include_directories(${PYTHON_INCLUDE_PATH})
set_source_files_properties(src/elec.i PROPERTIES CPLUSPLUS ON)
set_source_files_properties(src/elec.i PROPERTIES SWIG_FLAGS "-includeall")
link_directories(${COREALPI_LIBRARY})
swig_add_module(elecswig python src/elec.i)
swig_link_libraries(elecswig
${PYTHON_LIBRARIES}
elec
)
还有我给Swig的elec.i，它使用命名空间调用.h：
#define __linux__ 1
#define __GNUC__ 4
%module elecswig
%{
#include "ca/elec/model/modelvoltagedrop.h"
%}
%include "ca/elec/model/modelvoltagedrop.h"
当我尝试编译以获取我的Python Lybrary时，出现以下错误：

ISO C++ 2011 standard. This support is currently experimental, and must be \
enabled with the -std=c++11 or -std=gnu++11 compiler options.". Use the -cpperraswarn option to continue swig processing.

看来他找不到很多file.h，但是我大多数都遇到了c ++ 11错误。
我试图在CMake中设置Flags，但似乎没有任何改变。
你能帮我吗？
如果需要，我可以提供更多信息。
谢谢
经过数小时的测试，我找到了无法运行的原因。在CMakeLists中：
set_source_files_properties(src/elec.i PROPERTIES SWIG_FLAGS "-includeall")
包括所有库和依赖项，无论如何都要使用编译器。而且，如果您有2个版本的libstdc ++和gcc / g ++，看来他找不到链接/使用的好库。
如果我删除它，CMake会完成这项工作。我没有更多的unable to find还是c++11问题。
我必须使用g ++-5来使其工作（4.9似乎缺少c ++ 11的某些功能）并添加良好的名称空间和包含。
现在，我可以使用Python访问共享库。
