尝试使用 'aocl install' 安装 de5a_net_i2 驱动程序但失败

Question

我正在尝试安装 DE5-NET FPGA 的驱动程序。我在 Ubuntu 16.04 上使用面向 OpenCL 16.0 的英特尔 FPGA SDK。

aoc --list-boards 给出输出de5a_net_e1

但是在这一步之后，当我尝试运行 aocl install 时，我得到了

aocl install: Running install from /media/siladittya/fdc481ce-9355-46a9-b381-9001613e3422/siladittya/Softwares/AOCL/hld/board/de5a_net_e1/linux64/libexec

我尝试将 BSP 用于 board 文件夹中给出的其他默认值，但得到了相同的错误。

我猜当遇到警告时安装正在停止。

error: implicit declaration of function ‘send_sig_info’ [-Werror=implicit-function-declaration]

如何解决这个问题？

有什么办法吗？

新的 linux 内核进行了一些更改，并删除了一些不推荐使用的结构和方法。我必须更改 a10_ref 驱动程序源文件才能成功编译。 您可以对您的电路板进行相同的更改：

~/intelFPGA_pro/19.2/hld/board/a10_ref/linux64/driver：

    aclpci.c:

+   341    int ret = send_sig_info(aclpci->signal_number, tmp_alcpci_sig_inf, aclpci->user_task);
