Boost::python example on Ubuntu 12.04

Question

我正在尝试在Ubuntu 12.04上构建Boost：Python示例。我从软件包管理器中安装了库（不是来自源头）。我以前也没有使用过Boost，也没有为此设置任何环境变量（boost_build_path尚未设置）。我得到这个错误：

/usr/share/doc/libboost1.46-doc/examples/libs/python/example/tutorial$ bjam --debug-configuration
notice: found boost-build.jam at /usr/share/doc/libboost1.46-doc/examples/libs/python/example/boost-build.jam
Unable to load Boost.Build: could not find build system.
---------------------------------------------------------
/usr/share/doc/libboost1.46-doc/examples/libs/python/example/boost-build.jam attempted to load the build system by invoking
'boost-build ../../../tools/build/v2 ;'
but we were unable to find "bootstrap.jam" in the specified directory
or in BOOST_BUILD_PATH (searching /usr/share/doc/libboost1.46-doc/examples/libs/python/example/../../../tools/build/v2, /usr/share/boost-build).
Please consult the documentation at 'http://www.boost.org'.

我该如何修复？我应该在哪里指向boost_build_path？

Answer 1

我有同样的问题，我在这里找到了解决方案：

http://jayrambhia.wordpress.com/2012/06/25/configuring-boostpython-and-hello-boost/

事实证明，您根本不需要使用BJAM。filefile就足够了。我将在此处重复上述链接的解决方案：

1。）安装libboost-python软件包

2。）创建一个Hello World源文件，称为'Hello_ext.c'：

char const* greet()
{
    return "hello, world";
}
#include<boost/python.hpp>
BOOST_PYTHON_MODULE(hello_ext)
{
   using namespace boost::python;
   def("greet",greet);
}

3。）创建一个makefile：

PYTHON_VERSION = 2.7
PYTHON_INCLUDE = /usr/include/python$(PYTHON_VERSION)
# location of the Boost Python include files and library
BOOST_INC = /usr/include
BOOST_LIB = /usr/lib
# compile mesh classes
TARGET = hello_ext
$(TARGET).so: $(TARGET).o
    g++ -shared -Wl,--export-dynamic $(TARGET).o -L$(BOOST_LIB) -lboost_python -L/usr   /lib/python$(PYTHON_VERSION)/config -lpython$(PYTHON_VERSION) -o $(TARGET).so
$(TARGET).o: $(TARGET).c
    g++ -I$(PYTHON_INCLUDE) -I$(BOOST_INC) -fPIC -c $(TARGET).c

4。）make

make

5。）准备使用。在Python中：

import hello_ext
print hello_ext.greet()
