In most of the NVidia and AMD examples, the kernel code is kept in a separate .cl file and streamed in. In Apple’s HelloCL example, the kernel code is stored as a string in the file.<\/p>\n
The NVidia examples use a function – oclLoadProgStream. The AMD examples use a non-portable stream. Here’s how to do it without using any vendor-specific functions.<\/p>\n
#include <fstream><\/p>\n
…<\/p>\n
std::ifstream in;
\nstd::string KernelSource, line;<\/p>\n
…<\/p>\n
in.open(“hello.cl”);
\nif (in.is_open())
\nwhile (getline(in, line))
\nKernelSource += line + “\\n”;
\nelse
\n{
\nprintf(“Error: hello.cl does not exist!\\n”);
\nreturn EXIT_FAILURE;
\n}
\nin.close();<\/p>\n
Note that the end of line markers must be included, otherwise the number of characters in the string must be supplied.<\/p>\n
