Here's the basic code. Part of this is from my script generated implementation of OpenCL reading someone's post on these forums gave me the idea to wrap the entire CL in a single class, and I ran with it...
I left some slight amount of work for you to fill in...
Good luck!
#pragma once #include <cl.h> class DetectCL { typedef cl_int CL_API_CALL PclGetPlatformIDs( cl_uint, cl_platform_id*, cl_uint* ); typedef cl_int CL_API_CALL PclGetPlatformInfo( cl_platform_id, cl_platform_info, size_t, void*, size_t* ); DetectCL( const char* szDllLocation ) : m_hDLL( LoadLibraryA( szDllLocation ) ), m_pclGetPlatformIDs( NULL ), m_pclGetPlatformInfo( NULL ) { } ~DetectCL() throw() { FreeLibrary( m_hDLL ); } bool FInit() { m_pclGetPlatformIDs = (PclGetPlatformIDs *) ::GetProcAddress( m_hDLL, "clGetPlatformIDs" ); m_pclGetPlatformInfo = (PclGetPlatformInfo *) ::GetProcAddress( m_hDLL, "clGetPlatformInfo" ); return m_pclGetPlatformIDs != NULL && m_pclGetPlatformInfo != NULL; } // Method wrappers cl_int clGetPlatformIDs( cl_uint num_entries, cl_platform_id* platforms, cl_uint* num_platforms ) { return m_pclGetPlatformIDs( num_entries, platforms, num_platforms ); } cl_int clGetPlatformInfo( cl_platform_id platform, cl_platform_info param_name, size_t param_value_size, void* param_value, size_t* param_value_size_ret ) { return m_pclGetPlatformInfo( platform, param_name, param_value_size, param_value, param_value_size_ret ); } // Member declarations PclGetPlatformIDs* m_pclGetPlatformIDs; PclGetPlatformInfo* m_pclGetPlatformInfo; HMODULE m_hDLL; }; // Somewhere down in your .cpp file // szPath can be relative or absolute bool IsCLInstalled( const char* szPath ) { DetectCL cl( path ); if( !cl.FInit() ) return false; if( !cl.FInit() ) return false; cl_uint numPlatforms = 0; if( CL_SUCCESS != dll.clGetPlatformIDs( 0, NULL, &numPlatforms ) || numPlatforms < 1 ) return false; cl_platform_id* platforms = calloc( numPlatforms, sizeof( cl_platform_id ) ); if( CL_SUCCESS != dll.clGetPlatformIDs( numPlatforms, &platforms, NULL ) ) { free( platforms ); return false; } // You might want to add something else to figure out -- like what platform you want, etc. for( cl_uint iPlatform = 0; iPlatform < numPlatforms; ++iPlatform ) { // Fill in this detail here looking for what you want to determine. if( CL_SUCCESS != cl.clGetPlatformInfo( platforms[ iPlatform ], CL_PLATFORM_NAME or CL_PLATFORM_VERSION or CL_PLATFORM_VENDOR, ... ) ) { free( platforms ); return false; } } free( platforms ); return true; }
