Ubuntu 15.04 安装 boost-python

1. 安装依赖库

sudo apt-get install python-dev
sudo apt-get install mpi-default-dev #安装mpi库
sudo apt-get install libicu-dev  #支持正则表达式的ＵＮＩＣＯＤＥ字符集
sudo apt-get install libbze-dev  # 如果编译出现错误：bzlib.h : No such file or directory
sudo apt-get update

2. 手动安装Boost

2.1 下载 boost源代码，然后编译 boost （C++11 Python fPIC）,或者访问 boost.org.

#解压
unzip boost_1_63_0.zip

cd boost_1_63_0
./bootstrap.sh --with-python=PYTHON
./bootstrap.sh --with-libraries=system,thread,python

会生成 b2和bjam文件。可查看使用方法

./bootstrap.sh -help

2.2 编译 boost

sudo ./b2 install
./b2 cxxflags=-fPIC cflags=-fPIC --c++11

成功后会出现

The Boost C++ Libraries were successfully built!

2.3 建立一个 test.cpp文件测试

gedit test.cpp

添加如下内容

#include<iostream>
#include<boost/bind.hpp>
using namespace std;
using namespace boost;
int fun(int x, int y){return x+y;}
int main(){
int m=1; int n=2;
cout<<boost::bind(fun,_1,_2)(m,n)<<endl;
return 0;
}

编译

g++ test.cpp -o test

执行

./test

结果

3

3. 安装gflags

3.1 下载 gflags

安装命令，安装参数详细介绍见INSTALL.md

3.2 编辑CMakeList

gedit CMakeLists.txt

添加 -fPIC选项（在文件靠近开头的地方添加下面一行）：

set (CMAKE_POSITION_INDEPENDENT_CODE True)

生成Makefile

cmake .

检查是否在CMakeFiles/flags.cmake中成功生成-fPIC

grep -R fPIC ./build/CMakeFiles/

出现如下结果

./build/CMakeFiles/gflags_nothreads_static.dir/flags.make:CXX_FLAGS = -03 -DNDEBUG -fPIC
./build/CMakeFiles/gflags_static.dir/flags.make:CXX_FLAGS = -03 -DNDEBUG -fPIC

3.3 编译 gflags （+ fPIC）

make
make test   #(optional)
sudo make install

4. 配置

4.1 在工程的根目录下创建boost-build.jam，添加下列行

cd boost_1_63_0
gedit bootstrap.jam

添加如下内容

boost-build /home/bids/boost_1_63_0/tools/build/src

其中后面的这个路径应该为你本机里包含bootstrap.jam的路径。

然后在包装c++函数给python的源码文件目录中添加Jamroot文件。

4.2 编辑 jamroot

gedit jamroot

添加如下示例如下（详见中文注释）

# Copyright David Abrahams 2006. Distributed under the Boost
# Software License, Version 1.0. (See accompanying
# file LICENSE_1_0.txt or copy at http://www.boost.org/LICENSE_1_0.txt) 
import python ;

if ! [ python.configured ]
{
ECHO "notice: no Python configured in user-config.jam" ;
ECHO "notice: will use default configuration" ;
using python ;
}

# Specify the path to the Boost project.  If you move this project,
# adjust this path to refer to the Boost root directory.

# 注：此目录应该指向工程自己的boost-build.jam所在目录
use-project boost
: /home/bids/boost_1_63_0/tools/build/src ;

# Set up the project-wide requirements that everything uses the
# boost_python library from the project whose global ID is
# /boost/python.
# 注：下面示例动态库so工程，文件路径应该指向你自己的这两个.a文件的安装路径
project
: requirements <link>shared
<library-file>/usr/local/lib/libboost_python.a
<library-file>/usr/local/lib/libgflags.a
;

# Declare the three extension modules.  You can specify multiple
# source files after the colon separated by spaces.
# 注：此处应包含所有生成so所需要编译的源代码文件
python-extension word_net : wordnet_python_wrapper.cc wordnet_tool.cc word_tool.cc utils.cc ;

# Put the extension and Boost.Python DLL in the current directory, so
# that running script by hand works.
install convenient_copy
: word_net
: <install-dependencies>on <install-type>SHARED_LIB <install-type>PYTHON_EXTENSION
<location>.
;

# A little "rule" (function) to clean up the syntax of declaring tests
# of these extension modules.
local rule run-test ( test-name : sources + )
{
import testing ;
testing.make-test run-pyd : $(sources) : : $(test-name) ;
}

# Declare test targets
# 注：建议添加test脚本配置
run-test wordnet : word_net wordnet_python_test.py ;
