deel.boost.python

基于 Boost Version 1.59.0 / boost.python 修订

Description：

如果采用将boost.python源码嵌入工程编译的方式，可能会出现诸如以下警告（gcc4.8.3 / CYGWIN-NT-6.1 / i686-Cygwin / boost-1-59-0）：

boost-1.59.0 版本的python库和boost-1.57.0的python库相比有所改善, 但仍能看到很多这样的gcc的警告。

Avoid warning

避免这些gcc警告，有多种方式:

使用 gcc -Wno-* 选项，无视警告
更换较低版本的 g++
安装补丁
如果对以上方法都不满意，可以使用 deel.boost.python 代替 boost.python

Usage

更改源码文件.

在 C++ 代码文件中，将

1.1 #include <boost/python.hpp> 更换为 #include <deel.boost.python/boost/python.hpp>

1.2 #include <libs/python/ 开头的行更换为 #include <deel.boost.python/libs/python/
添加gcc编译选项.

gcc 添加 -I/path/to/deel.boost.python/../ 选项

deel.boost.python 依赖于boost库(推荐 boost-1.57.0以上) 和 python-dev

#####step 1. 查找所有包含 #include <boost/python/ 、 #include <boost/python.hpp> 和 #include <libs/python/ 的文件。

$ grep -nr "#\s*include\s*<boost\/python" *
$ grep -nr "#\s*include\s*<libs\/python\/" *

#####step 2. 将 #include <boost/python.hpp> 替换为 #include <deel.boost.python/revise/boost/python.hpp>

$ REPLACE=deel.boost.python\\\/revise\\\/

$ sed -i "s/\(#\s*include\s*<\)\(boost\/python.hpp\)/\1${REPLACE}\2/g" `grep -rl "#\s*include\s*<boost\/python.hpp>" *`

######step 3. 将 #include <boost/python/ 替换为 #include <deel.boost.python/revise/boost/python/

$ REPLACE=deel.boost.python\\\/revise\\\/

$ sed -i "s/\(#\s*include\s*<\)\(boost\/python\/\)/\1${REPLACE}\2/g" `grep -rl "#\s*include\s*<boost\/python\/" *`

#####step 4. 将 #include <libs/python/ 替换为 #include <deel.boost.python/revise/libs/python/

$ REPLACE=deel.boost.python\\\/revise\\\/

$ sed -i "s/\(#\s*include\s*<\)\(libs\/python\/\)/\1${REPLACE}\2/g" `grep -rl "#\s*include\s*<libs\/python\/" *`
