looking for help - macOS , openCL not being recognized #851

Closed MichaelB7 closed 5 years ago

MichaelB7 commented 5 years ago

first , I have this lcode that identifies that both my CPU and GPU supports openCL Mac Pro 2010 macOS Mojave v 10.14.4 Display Chipset Model: AMD Radeon HD 7950

#include <stdio.h>
#include <stdlib.h>
#include <OpenCL/opencl.h>

int main(int argc, char* const argv[]) {
    cl_uint num_devices, i;
    clGetDeviceIDs(NULL, CL_DEVICE_TYPE_ALL, 0, NULL, &num_devices);

    cl_device_id* devices = calloc(sizeof(cl_device_id), num_devices);
    clGetDeviceIDs(NULL, CL_DEVICE_TYPE_ALL, num_devices, devices, NULL);

    char buf[128];
    for (i = 0; i < num_devices; i++) {
        clGetDeviceInfo(devices[i], CL_DEVICE_NAME, 128, buf, NULL);
        fprintf(stdout, "Device %s supports ", buf);

        clGetDeviceInfo(devices[i], CL_DEVICE_VERSION, 128, buf, NULL);
        fprintf(stdout, "%s\n", buf);
    }

    free(devices);
}

compile with this

 clang -framework OpenCL hello.c -o hello

the output displays this:

Mac-Pro:src $ ./hello
Device Intel(R) Xeon(R) CPU           X5690  @ 3.47GHz supports OpenCL 1.2 
Device AMD Radeon HD 7950 Compute Engine supports OpenCL 1.2 
Mac-Pro:src $

but for the life of me , I can not longer build a version that supports OpenCL as a backend. I know it's related to something "Apple" did ,as I was able to build an lc0 version supporting OpenCL back in January. I'm just looking for a way to build a current version today. Any help appreciated.

If I force it to build an OpenGL supported version, it fails here:

Please ask questions like this in the discord. The problem looks like missing dependencies.

A final comment ,was able to resolve the issue by using clang instead of gcc. If you have gcc as the default . then preface the build command as so:

CC=clang CXX=clang++ ./build.sh
