当我从 CUDA SDK 运行 devicequey 时，出现分段错误错误：

其他示例如何正常工作。甚至 devicequeryDrv 编译正确。

我也得到了smokeParticle示例的浮点异常

谢谢你的帮助

CUDA 驱动程序版本/运行时版本 4.2/4.0

看起来您的 CUDA 驱动程序和运行时版本不同。当两者相同时，你会得到 seqfault 吗？尝试重新安装 4.2 并确保所有工具都指向正确的工具包版本。

我不知道发生了什么，但是当我使用cula的最新版本时，我得到了相同版本的 cuda 运行时和驱动程序，但是当我降级到像 r12 这样的旧版本时，它会自动降级我的 cuda 运行时版本并导致得到错误。我测试了三遍（升级，降级）。我不知道这是可能的/
