c++ version supported by cuda 5.0

Question

I can't find which version/which concepts of c++ is/are supported by CUDA 5.0. I could not find any information in the Programming Guide or Reference Guide delivered with the CUDA 5.0 RC. Especially I'm wondering if CUDA 5.0 supports C++11. Could someone point me to a place to look for this information?

Answer 1

Apperently no C++11 features are available in 5.0 RC. nvcc still does not understand C++11 syntax used in the standard includes of gcc 4.6 (see Error while using CUDA and C++11):

$ nvcc --version

$ cat test.cu

int main()

}

$ nvcc -Xcompiler "-std=c++0x" test.cu

Answer 2

The release notes contain a list of support platforms including which versions of GCC are supported, the 5.0 Release Candidate release notes show that the most recent supported GCC is 4.6 for certain distributions (and older for other distributions).

Once you know which GCC version is supported, compare with the GCC C++0x/C++11 feature list.

Answer 3

It does not support gcc 4.7 so some of the c++11 features are not available:

- Non-static data member initializers
- Template aliases :(
- Delegating constructors
- User-defined literals
- Extended friend declarations
- Explicit virtual overrides
