implicit declaration of function ‘send_sig_info’ error

Hi,

I am a student. I want to use OPenCL to write code for my FPGA. I installed FPGA SDK standard edition 17.1 in Ubuntu 16.04. After that I installed intel fpga runtime environment for opencl linux x86-64. After sourcing the script init_opencl.s, I was able to verify my installation using 'aocl version' command. After that I tried to install an FPGA board. So I tried the command 'aocl install' command.

It stopped with an error saying/tmp/opencl_driver_tf7ebm/aclpci.c:343:17: error: implicit declaration of function ‘send_sig_info’ [-werror=implicit-function-declaration] int ret = send_sig_info(aclpci->signal_number, &aclpci->signal_info, aclpci-

Complete output of the command: 

/media/deepak/82d940f9-6526-47c8-8053-79204d78529f/deepak/intelFPGA/17.1/aclrte-linux64/board/a10_ref?  y

    Thanks. I have now installed it in Windows 10. But the problem now is that aoc command is compiling a hello world program for DE2 board for 2.5 hours.

    The command I used:

    aoc device\hello_world.cl -o bin\hello_world.aocx --board de5net_a7

    hello_world.aocx content:

    // AOC kernel demonstrating device-side printf call

    __kernel void hello_world(int thread_id_from_which_to_print_message) {

    // Get index of the work item

    unsigned thread_id = get_global_id(0);

    if(thread_id == thread_id_from_which_to_print_message) {

    printf("Thread# %u: Hello from Altera's OpenCL Compiler!\n", thread_id);

    }

    }

    The following is message after executing the above command:

    Warning: Please use -board=<value> instead of --board <value>

    aoc: Running OpenCL parser....

    aoc: Optimizing and doing static analysis of code...

    Compiling for FPGA. This process may take a long time, please be patient.

    Still the compilation has not stopped.

    Depending on the characteristics of your machine (CPU speed, memory size, etc.) the compilation could take multiple hours.

    Okay I understand. The reason why asked is that the kernel code looks simple and yet it took lot of time. That is why I asked. Thanks anyway

    EBozo's fix also worked for me - thanks! Much better than Altera's response of 'Ubuntu not supported' 🙂
