使用rpmbuild制作rpm包

这里以制作cmake-3.15.5为例，首先保证环境中安装有rpmbuild，其次下载cmake-3.15.5.tar.gz源代码包，下载地址见下spec文件。

rpmbuild –ba cmake.spec生成打包目录

这个命令可以在任意目录下执行，执行后会报如下错误

这里报错正常，因为此时并没有cmake.spec文件，这个文件是需要我们手工编写的。

执行完成后会发现在/root目录下形成了rpmbuild目录.

如果没有在/root下形成，可以修改/usr/lib/cpm/macros文件中的_topdir宏，这里不再过多解释.

关于rpmbuild目录的结构含义这里不过多解释。

vi ~/rpmbuild/SPECS/cmake.spec 自动生成spec模板文件，并填写相关字段，现给出我的spec文件

关于spec文件的具体字段含义这里不过多解释。

执行 rpmbuild ~/rpmbuild/SPECS/cmake.spec

接下来是比较长的编译和安装过程，当完成后会发现在BUILD目录下有cmake-3.15.5.tar.gz的解压后的文件夹，BUILDTOOR目录下有已经被安装完成的cmake的文件

解析rpm包

rpm –qpl *.rpm # 列出rpm包包含的内容

rpm2cpio *.rpm | cpio –div # 解压rpm包
