Hello !
I want to save the binary (after my clBuildProgram) on a file, so this is my code :
err = clBuildProgram(plan->program, 1, &devices[0], "-cl-mad-enable", NULL, NULL); //build the program
err = clGetProgramInfo(plan->program, CL_PROGRAM_NUM_DEVICES, sizeof(size_t), &nb_devices, &nbread);// Return 1 devices
size_t *np = new size_t[nb_devices];//Create size array
err = clGetProgramInfo(plan->program, CL_PROGRAM_BINARY_SIZES, nb_devices, &np, &nbread);//Load in np the size of my binary
char** bn = new char* [nb_devices]; //Create the binary array for(int i =0; i <nb_devices;i++) bn = new char[70000]; // I know... it's bad... but if i use new char[np], i have a segfault... 😕
err = clGetProgramInfo(plan->program, CL_PROGRAM_BINARIES, nb_devices, bn, &nbread); //Load the binary itself
printf("%s\n", bn[0]); //Print the first binary. But here, I have some curious characters
fp = fopen("binar.bin", "wb"); fwrite(bn[0], sizeof(char*), 70000, fp); // Save the binary, but my file stay empty
I don't know how to retrieve the binary, my clBuildProgram work (and my binary too), but i think i'm doing something wrong on my program.
If someone can help me, thank you !

Hi bleveque,
you can try this.
err = clBuildProgram(program, 1, &devices[0], "-cl-mad-enable", NULL, NULL); //build the program
err = clGetProgramInfo(program, CL_PROGRAM_NUM_DEVICES, sizeof(size_t), &nb_devices, &nbread);// Return 1 devices
size_t *np = new size_t[nb_devices];//Create size array
err = clGetProgramInfo(program, CL_PROGRAM_BINARY_SIZES, sizeof(size_t)*nb_devices, np, &nbread);//Load in np the size of my binary
char** bn = new char* [nb_devices]; //Create the binary array
for(int i =0; i < nb_devices;i++) bn = new char[np]; // I know... it's bad... but if i use new char[np], i have a segfault... 😕
err = clGetProgramInfo(program, CL_PROGRAM_BINARIES, sizeof(unsigned char *)*nb_devices, bn, &nbread); //Load the binary itself
printf("%s\n", bn[0]); //Print the first binary. But here, I have some curious characters
FILE *fp = fopen("binar.bin", "wb");
fwrite(bn[0], sizeof(char), np[0], fp); // Save the binary, but my file stay empty
fclose(fp);
and you can use clCreateProgramWithBinary to build program with binary.

Thanks, it works !
(I have the same problem with "new char[np]" because np in undefined, but the rest of the algo works
