When OpenCL™ applications are compiled with MinGW-w64, the application exits when an OpenCL™ runtime routine is called.This is a known issue with the MinGW-w64 compiler.Whereas the MinGW (32-bit) compiler does not require a libopencl.a file, MinGW-w64 does require such a file. When a libopencl.a file is not available and specified during the link stage, no link errors are reported. However, execution of the resulting binary executable terminates whenever an OpenCL™ runtime routine is called.The recommended work around until this is resolved in the MinGW-w64 is to generate a libopencl.a file from the OpenCL.dll provided with the ATI Stream SDK v2 installation.You will need to make sure the following tools are installed on your system: * gendef (a MinGW-w64 utility) * dlltool (a MinGW-w64 utility)Run the following commands to generate libopencl.a from OpenCL.dll: 1. gendef OpenCL.dll (this generates an OpenCL.def file) 2. dlltool -l libopencl.a -d OpenCL.def -k -A 3. Copy the resulting libopencl.a file into $ATISTREAMSDKROOT\lib.When compiling an OpenCL™ application with MinGW-w64, make sure to specify the libopencl.a file as part of the input into the link stage of the compilation.
