Above is the method explanation of getBuildInfo, anyone knows how to call it? I’ve try in many ways but no success. I also refer to examples such as std::string buildlog = program.getBuildInfo<CL_PROGRAM_BUILD_LOG>(dev);
But my question is why in this way as the explanation of the method is using () instead of <>?
Besides, if the build success is successful will any log be shown, or will the log only be shown when the build is not success?
In short, the example described above is correct: CL_PROGRAM_BUILD_LOG is the template parameter and is specified in <>, and dev is the device to query that is passed using ().
The contents of the build log are implementation-defined when the build succeeds. Some implementations include a generic “success” message, other implementations include information about the build such as whether the kernel was vectorized or not, and other implementations include nothing at all.
