我已经在我的电脑上安装了CUDA工具包,但似乎有些事情已经破裂.在nvcc无法编译,既不是简单的hello世界是这样的:
#include <stdio.h>
int main(int argc, char** argv) {
printf("Hello, world!\n");
return 0;
}
输出是:
$ nvcc hello.cu
/usr/include/c++/4.8.0/cstdlib(178): error: identifier "__int128" is undefined
/usr/include/c++/4.8.0/cstdlib(179): error: identifier "__int128" is undefined
2 errors detected in the compilation of "/tmp/tmpxft_000011a2_00000000-6_hello.cpp1.ii".
详细输出是:
$ nvcc --verbose hello.cu

最后但并非最不重要的是,这是有问题的头文件:http://pastebin.com/WtUckrYv
先感谢您.
CUDA 5.0与gcc 4.8.0不兼容.
为了更好地理解兼容的发行版和gcc版本,请参阅发行说明.
你可能有更好的运气cuda 5.5 RC,但你提到的特定发行版以及gcc版本仍然没有列在linux支持下的发行说明中.
通过切换到支持的发行版,最有可能找到最佳体验.
通常,nvcc在CUDA 5中将自动包含/usr/local/cuda/include/host_config.h具有各种宏的文件来检查正确/可接受的编译器版本,并且其中一个宏应该在您的情况下抛出错误,但它似乎没有:
#if defined(__GNUC__)
#if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 6)
#error -- unsupported GNU version! gcc 4.7 and up are not supported!
#endif /* __GNUC__> 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 6) */
#endif /* __GNUC__ */
