问题描述
尝试在 Fedora 34 Docker 映像中构建 OpenMPI 时，我收到以下链接器错误：
#22 77.36 make[2]: Entering directory '/build/openmpi-4.1.1/opal/tools/wrappers'
#22 77.37 CC opal_wrapper.o

#22 77.81 collect2: error: ld returned 1 exit status
我的配置命令只是 ./configure --prefix=/usr/local/openmpi。
我也尝试过 ./configure --prefix=/usr/local/openmpi --disable-silent-rules --enable-builtin-atomics --with-hwloc=/usr --with-libevent=external --with-pmix=external --with-valgrind（类似于用于 OpenMPI 的 Fedora 规范文件中的内容），但会产生相同的错误。
解决方法
在我在 OpenMPI 用户列表上发布 message 后，某人 pointed out the line
../../libtool: line 5705: find: command not found
在 make output 中。 Fedora 中的 find 命令由 findutils 包提供。在映像中安装 findutils 后，我能够成功构建 OpenMPI。
