我正在尝试编译一个需要链接到 boost-python的 Python库（CEGUI 可以构建 Python 模块，它的编辑器依赖于它）。所以我用--with-python构建了 boost，它构建得很好。
但是，一旦 .pyd 被链接，我就会得到未定义的引用：

我的第一个假设是它没有链接到 boost-python，但是 CMake 文件夹中的 link.txt 显示了这一点：
"C:\Coding\CMake 2.8\bin\cmake.exe" -E 删除 -f CMakeFiles\PyCEGUI.dir/objects.a C:\MinGW\bin\ar.exe cr CMakeFiles\PyCEGUI.dir/objects.a @ CMakeFiles\PyCEGUI.dir\objects1.rsp C:\MinGW\bin\g++.exe -shared -o ..........\bin\PyCEGUI.pyd -Wl,--major-image-version, 0,--minor-image-version,0 -Wl,--whole-archive CMakeFiles\PyCEGUI.dir/objects.a -Wl,--no-whole-archive ..........\lib \libCEGUIBase-0.dll.a C:\Coding\boost_1_53_0\lib\libboost_python-mgw48-mt-1_53.a C:\Python27\libs\python27.lib C:\Coding\CEGUI\cegui\dependencies\lib\dynamic \libfreetype.dll.a C:\Coding\CEGUI\cegui\dependencies\lib\dynamic\libpcre.dll.a -lwinmm -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32
所以 boost-python 是针对的。我不确定这里可能是什么问题。促进？CEGUI？闵玧其？...
