firefox-45 套件實例

  1. 緣由：firefox v38.6 某些網頁還是會當掉。
  2. v45 firefox hello 視訊 (video+audio) 包含文字聊天室，但文字有部分遺漏待處理。
  3. v38 facebook 中文輸入有問題，v45 已解決此問題。
  4. v45 必須修改字型設定，註解以下部分，否則網頁細明體字不够清楚。 
    [dywang@dywnb ~]$ tail -29 .fonts.conf

</fontconfig>

  5. 下載 SRPM 套件 
    [dywang@dywnb ~]$ cd rpmbuild
[dywang@dywnb rpmbuild]$ wget ftp://bo.mirror.garr.it/2/scientific/6x/\
SRPMS/vendor/firefox-45.1.0-1.el6_7.src.rpm
  6. 安裝 SRPM 套件 
    [dywang@dywnb rpmbuild]$ rpm -ivh firefox-45.1.0-1.el6_7.src.rpm 
warning: firefox-45.1.0-1.el6_7.src.rpm: Header V4 DSA/SHA1 Signature, key ID 192a7d7d: NOKEY

  7. 查看安裝的所有檔案。 
    [dywang@dywnb rpmbuild]$ cd SOURCES/
[dywang@dywnb SOURCES]$  rpm -qpl ../firefox-45.1.0-1.el6_7.src.rpm

  8. 查看程式主要的打包壓縮檔。 
    [dywang@dywnb SOURCES]$ ls firefox-45.1.0esr.source.tar.xz 
firefox-45.1.0esr.source.tar.xz
  9. 解壓縮原始碼 tarball，產生 firefox-45.1.0esr 目錄，存放原始碼。 
    [dywang@dywnb SOURCES]$ tar xJvf firefox-45.1.0esr.source.tar.xz
  10. 查看 firefox-45.1.0esr 目錄內的檔案。 
    [dywang@dywnb SOURCES]$ ls firefox-45.1.0esr
