我在编译 CUDA SDK 附带的一些示例时遇到了麻烦。 我已经安装了开发人员驱动程序(版本270.41.19)和 CUDA 工具包, 最后是 SDK (都是4.0.17版本)。
最初它根本没有编译:
error -- unsupported GNU version! gcc 4.5 and up are not supported!
我在81:/usr/local/cuda/include/host _ config.h 中找到了相应的代码行,并将其更改为:
//#if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 4)
#if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 6)
从那时起,我只得到了一些要编译的示例,它停止于:

作为一些例子编译,我认为这不是驱动程序的问题,而是与不支持的 gcc 版本有关。降级不是一个选项,因为 gcc4.6在这一点上有一个完整的系统作为依赖..。
