firefox-60 套件實例

  1. 緣由：firefox v52 無法使用 hangout 視訊。
  2. 下載 SRPM 套件 
    [dywang@dyw219 ~]$ cd rpmbuild
[dywang@dyw219 rpmbuild]$ wget ftp://ftp.pbone.net/mirror/ftp.redhat.com/pub\
/redhat/linux/enterprise/6ComputeNode/en/os/SRPMS/firefox-60.9.0-1.el6_10.src.rpm
  3. 安裝 SRPM 套件 
    [dywang@dyw219 rpmbuild]$ rpm -ivh firefox-60.9.0-1.el6_10.src.rpm
  4. 查看安裝的所有檔案。 
    [dywang@dyw219 rpmbuild]$ rpm -qpl firefox-60.9.0-1.el6_10.src.rpm

  5. 查看程式主要的打包壓縮檔。 
    [dywang@dyw219 SOURCES]$ cd SOURCES/
[dywang@dyw219 SOURCES]$ ls firefox-60.9.0esr.source.tar.xz 
firefox-60.9.0esr.source.tar.xz
  6. 解壓縮原始碼 tarball，產生 firefox-45.1.0esr 目錄，存放原始碼。 
    [dywang@dyw219 SOURCES]$ tar xJvf firefox-60.9.0esr.source.tar.xz
  7. 查看解壓縮目錄 firefox-60.9.0 內的檔案。 
    [dywang@dyw219 SOURCES]$ ls firefox-60.9.0

  8. 進入暫存目錄 tmp，解開原始 src.rpm，方便做修改的比對。 
    [dywang@dyw219 tmp]$ rm ./* -rf
