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,然后安装了SDK(均为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中找到负责的行,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,我只编译了几个示例,其结尾为:
In file included from /usr/include/c++/4.6/x86_64-linux-gnu/bits/gthr.h:162:0,
from /usr/include/c++/4.6/ext/atomicity.h:34,

make[1]: *** [obj/x86_64/release/lineOfSight.cu.o] Error 1
正如一些示例可以编译一样,我认为这不是驱动程序问题,而是与不支持的gcc版本有关。降级不是一种选择,因为此时gcc4.6将整个系统作为依赖项...
