Docker 构建找不到 G++，手动运行该步骤有效

Question

我的镜像试图在 centos7 基础上从源代码构建 protobuf 3.9.1。更新和安装依赖项后，第一步是运行来自 protobuf 存储库的 ./configure 脚本。这通过并找到构建所需的一堆依赖项。

docker build 在 RUN ./configure 上失败，原因是 checking for g++... no。当通过直接在失败步骤之前的层中执行 docker run 手动运行ning 脚本时，./configure 能够找到 g++：checking for g++... g++.

关于 docker build 和手动运行之间可能导致这种不同行为的任何建议？感谢阅读！

Docker 文件:

RUN mkdir -p $PROJECTDIR

我试过 docker 构建有无 cacche 没有影响

您缺少 GNU Compiler Collection，因此应将其作为依赖项安装。

If you are trying to build using make, ensure you've installed the gcc-g++ package! Without it, your build will fail in the way you are seeing.

在配置前安装gcc-c++

RUN yum install gcc-c++ -y

此外，更正您缺少的配置命令 && \

RUN yum install gcc-c++ -y
RUN ./configure && \
    make && \
    make check && \
    make install && \
    ldconfig
