使用gcc4.7.1构建boost 1.57

Question

我正在尝试在Win7 64b上使用与CodeBlocks绑定的GCC 4.7.1构建Boost 1.57。

我这样做了：

mkdir c:\boost\build
cd c:\boost\tools\build\v2
bootstrap.bat gcc
b2 install --prefix=C:\boost\build
set PATH=%PATH%;C:\boost\build\bin
cd c:\boost
b2 --build-dir=C:\boost\build toolset=gcc --build-type=complete

我明白了：

error: Name clash for '<pstage\lib>libboost_exception-mgw47-mt-1_57.a'

error: Tried to build the target twice, with property sets having
error: these incompabile properties:

error:     -  none
error:     -  <linkflags>-shared-libgcc <linkflags>-shared-libstdc++

error: Please make sure to have consistent requirements for these
error: properties everywhere in your project, especially for install
error: targets.

我错过了什么吗？
