Yocto上的v4l2loopback

Question

我在Yocto上乞讨，我试着把v4l2loopback添加到我的形象中

我在github (https://github.com/umlaeute/v4l2loopback)上下载了当前的源代码，并尝试用recipe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，但我不知道如何修补

请帮帮我

谢谢

v4l2loopback的Makefile没有modules_install目标。但是，install目标将执行预期的操作。

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

MODULES_INSTALL_TARGET = "install"
