module - Yocto 上的 v4l2loopback

问题描述

我是 Yocto 的初学者，我尝试将 v4l2loopback 添加到我的图像中

我在 github ( https://github.com/umlaeute/v4l2loopback ) 上下载了当前源代码，并尝试使用配方进行编译

SUMMARY = "V4L2Loopback"
DESCRIPTION = "v4l2loopback module"
LICENSE = "GPLv2"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/GPL-2.0;md5=801f80980d171dd6425610833a22dbe6"


# Use local tarball
SRC_URI = "file://v4l2loopback-master.tar.gz"

# Make sure our source directory (for the build) matches the directory structure in the tarball
S = "${WORKDIR}/v4l2loopback-master"

inherit module

KERNEL_MODULE_AUTOLOAD = "v4l2loopback"

bitbake 给我：

我想我必须修补 Makefile 但我不知道如何

请帮我

谢谢

解决方案

v4l2loopback 的 Makefile 没有modules_install目标。但是，install目标将按照预期进行。

inherit module您可以通过在配方中添加以下内容来替换用于模块安装步骤的目标：

MODULES_INSTALL_TARGET = "install"
