I am having troubles using the Unified Backend library af.lib, but my program is working when I am using other libraries.
Description
My program is perfectly working if I am using afcpu.lib: the code I use is presented below with the output obtained. But it won't work if I am using af.lib. I also put the code and the output right after.
Reproducible Code and/or Steps (working)
- Add $(AF_PATH)/include; to Project Properties -> C/C++ -> General -> Additional Include Directories.
- Add $(AF_PATH)/lib; to Project Properties -> Linker -> General -> Additional Library Directories.
- Add afcpu.lib; to Project Properties -> Linker -> Input -> Additional Dependencies.
Here is the code used:
#include <iostream>
#include <arrayfire.h>
int main()
{
std::cout << "Main running..." << std::endl;
std::cout << "Available backends: " << af::getAvailableBackends() << std::endl;
for (int i = 0; i < af::getDeviceCount(); i++) {
af::setDevice(i);
af::info();
}
return 0;
}
Here is the output:
Main running...
Available backends: 1

}
catch (af::exception& e)
{
std::cout << "Caught exception when trying reading backends" << std::endl;
std::cerr << e.what() << std::endl;
}
af::setBackend(AF_BACKEND_CPU);
for (int i = 0; i < af::getDeviceCount(); i++) {
af::setDevice(i);
af::info();
}
af::setBackend(AF_BACKEND_CUDA);
for (int i = 0; i < af::getDeviceCount(); i++) {
af::setDevice(i);
af::info();
}
af::setBackend(AF_BACKEND_OPENCL);
for (int i = 0; i < af::getDeviceCount(); i++) {
af::setDevice(i);
af::info();
}
return 0;
}
Here is the output:
If I am running it with the Visual Studio Debugger, here is the error I obtain:
