OSG 2.7.9 MinGW编译问题

x_wp

环境：WINXP SP2，MinGW 5.1.4，CMake 2.6.2，OSG 2.7.9
错误：用CMake生成MinGW Makefile时只将BUILD_OSG_WRAPPERES设置为ON，其余默认，在编译osgIntrospection时出错：

OSG 2.7.8 编译时也是同样的问题，在Ubuntu 8.10下用GCC 4.3.2编译OSG 2.8.0 rc1（同样CMAKE中只改了BUILD_OSG_WRAPPERES一项）顺利通过。

我没有试验过，可能是MinGW编译库还需要别的包含头文件（例如iostream）？不知道2.8版本会不会有人提出并修正这个问题。
osgIntrospection的作用是提供OSG与C++以外的其它语言的封装能力，如果用不到的话，也可以不选择它；也欢迎x_wp确认并在osg-users上提出这个问题，帮助2.8稳定版本的完善

用官方的MINGW编译了几个版本了（包括OSG2.8rc1、rc3），都是这个问题，我在OSG-USER上问了也没人理我，实在不行就不编译OSGWAPPER了，正如版主所言，现在暂时不用。以前用TDM的GCC4.3.2编译老出问题，查了些资料才知道是TDM GCC4.3.2的一个BUG，TDM马上要更新了，等更新了再用4.3.3编译一下，希望可以通过。

还想问一个MINGW/GCC的问题，编译第三方库时不支持CMAKE，只好装了个MSYS，在MSYS环境下用configure、make、make install来编译安装。看了些资料GCC编译时-g参数表示编译DEBUG库，可是不知道如何设置参数可以在编译生成的文件名后自动加个d，以便于release库区别？谢谢！

如果工程本身没有设置DEBUG库加上d后缀的话，那么就没有办法，除非手动改Makefile；这也是我们选用CMake来自动生成MakeFile的原因之一
