我正在尝试在较旧的嵌入式 Linux 系统上构建最新版本的 bind9。
我在构建命名时遇到此错误：

我尝试使用 -pthread 而不是 -lpthread，结果仍然相同。
老最重要的事实是 glibc 是 2.24 对绑定版本 17.17 的 glibc 版本有一些版本要求吗？
构建链使用这些选项通过 cmake 配置 bind9
--enable-ipv6=no \
--with-randomdev=/dev/random \
--disable-threads \
--disable-devpoll --disable-epoll \
--disable-doh \
--disable-linux-caps \
--sysconfdir=${sysconfdir}/bind \
--with-openssl=${TARGET_SYSROOT}${target_prefix} \
--with-gssapi=no \
--enable-exportlib \
--with-export-includedir=${includedir} \
--with-export-libdir=${libdir} \
--with-eddsa=no \
--without-libnghttp2 \
--disable-silent-rules \
一件奇怪的事情是，当我添加了--disable-threads（删除--disable-threads 不会改变任何东西）时，根本就使用了pthreads
我的构建链将其标识为 arm-cortexa7hft-linux-gnueabi
我读了很多关于这种错误的文章，但似乎没有一个匹配。
编辑：
我找到了错误的原因。Bind 使用 libuv，而我使用的版本（最新的 1.42.0）正在调用 pthread_atfork，但由于它被隐藏，所以它失败了。取消注释 pthread_atfork 使其可以编译，但这并不明智。
我现在将尝试在 libuv 上提出一个问题。
