rpmbuild %install 部分删除 buildroot 代码。我如何防止 rpmbuild 这样做

Question

我正在为 rails 应用创建一个新的 rpm。但是，%install 部分的默认行为会删除 BUILDROOT 目录。我假设 %install 部分将从 buildroot 安装文件。我一定是做错了什么，因为 buildroot 在 %install 部分被删除了。这样做的正确方法是什么？

这是规范文件

A rewrite of railsapp from the HTML version to a Http API version

%prep
        echo "BUILDROOT = $RPM_BUILD_ROOT"
        rm -rf $RPM_BUILD_ROOT
        mkdir -p $RPM_BUILD_ROOT/usr/local/veex/railsapp
        unzip /home/realworx/rpmbuild/SOURCES/rwx-master.zip -d $RPM_BUILD_ROOT/usr/local/veex/
        pushd $RPM_BUILD_ROOT/usr/local/veex/
        rm -rf railsapp
        mv rwx-master railsapp
        pushd $RPM_BUILD_ROOT/usr/local/veex/railsapp
        rm Gemfile.lock
        bundle install
        PWD=`pwd`
        cat > gemrc <<EOGEMRC
gemhome: $PWD/vendor/bundle/ruby/1.8
gempath:
- $PWD/vendor/bundle/ruby/1.8
EOGEMRC
        gem --config-file ./gemrc install bundler
        # Don't need the gemrc any more...
        rm ./gemrc


%files
%attr(0744, root, root) /usr/local/veex/railsapp/*
%install
echo %{buildroot}
echo "HELLO"

%clean
echo NOOP

下面是 %install 删除 buildroot 的日志。

如何防止 %install 删除我的 buildroot？

Answer 1

您误用了 %prep 部分。简而言之，您应该如何使用这些部分：

%prep：提取您的源代码、应用补丁等
%build：编译或构建您的应用程序（如果需要）
%install: 将文件复制到$RPM_BUILD_ROOT

因此 $RPM_BUILD_ROOT 在 %isntall 部分的开头被清空是合乎逻辑的。

更改代码以在 %prep 中提取 zip 文件，并使用 %install 部分将文件放入 $RPM_BUILD_ROOT.
