Hello everyone. I am trying to get some of the first examples from Cuda by Example to compile via nvcc, with no luck.
Whether I include book.h or not, I get 76 errors, most of which are similar to one of the following:
Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include\vcruntime.h(184): error: invalid redeclaration of type name “size_t”
Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include\vcruntime_new.h(66): error: first parameter of allocation function must be of type “size_t”
Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include\type_traits(168): error: class template “std::_Is_function” has already been defined
nvidia gpu computing toolkit\cuda\v10.0\include\sm_20_intrinsics.hpp(108): error: asm operand type size(8) does not match type/size implied by constraint ‘r’
The example I am trying to compile is attached at the end of this message. Any suggestions are welcome. I have been using the command nvcc Example25.cu 2> log.txt to compile. This may not be the right way to do things, and if so please point me to detailed instructions.
Thanks!
