Question

我有一个有效的buildroot版本（2017.02.1）。我需要添加mDNS。使用配置菜单，我设法添加并构建第一个avahi auto ip选项。当我添加mDNS和libdns_sd子选项时，构建失败（下面）。我删除了＆＃39; dbus＆＃39;来自＆＃39; fs_skeleton / etc / passwd＆＃39;但构建仍然失败。我是buildroot＆amp;的新手。所以任何指针都会有所帮助！

mkdir -p /home/user/buildroot-mywork/buildroot/output/target/etc

    echo "NAME=Buildroot"; \
    echo "VERSION=2017.02.1-00039-g464795e"; \

    echo "VERSION_ID=2017.02.1"; \
    echo "PRETTY_NAME=\"Buildroot 2017.02.1\"" \

这看起来很奇怪。在确定后，请将此错误报告给Buildroot错误跟踪器： 1 /您可以在完全干净的构建后重现（make clean all） 2 /您包含一个允许重现问题的Buildroot .config文件。

在buildroot中启用mDNS
