win7 codeblock在调用boost::thread遇到的错误——解决办法

使用boost::thread库时可能会碰到如下错误 （Linux下 gcc4.4+boost1.40）

或者以下错误  （windows gcc4.5+boost1.45）

以上错误是由于未导入thread的静态链接库，解决方法如下

如果使用boost::thread,使用静态链接时 即编译boost库时使用选项link=static runtime-link=static
对于ubuntu下，需要在project的build options中linker settings--》other linker options中添加-lboost_thread
对于windows下，需要在project的build options中linker settings--》link libraries中添加boost_1_45\lib\libboost_thread-mgw45-mt-1_45.a(注意，debug和release要田间对应的库文件)，并修改头文件（boost_1_45\include\boost_1_45\boost\thread\detail\config.hpp）中第40行，在末尾添加宏 || defined(MINGW32)，同时在build options中compiler settings中的#defines添加MINGW32或者一劳永逸地在全局设定中添加此宏（settings-->compiler and debugger-->compiler settings-->#defines中添加红MINGW32）
使用动态链接库时，即编译boost库时使用选项link=shared runtime-link=shared
对于windows下，需要在project的build options中linker settings--》link libraries中添加boost_1_45\lib\libboost_thread-mgw45-mt-1_45-dll.a(注意，debug和release要田间对应的库文件),并将此dll文件拷贝到编译的可执行程序根目录下
