gtk2-engines 套件實例

下載 SRPM 套件

[dywang@dywH ~]$ cd rpmbuild
[dywang@dywH rpmbuild]$ wget ftp://ftp.pbone.net/mirror/vault.centos.org/6.3\
/os/Source/SPackages/gtk2-engines-2.18.4-5.el6.centos.src.rpm

查看安裝的所有檔案。

[dywang@dywH rpmbuild]$ rpm -qpl gtk2-engines-2.18.4-5.el6.centos.src.rpm 
gtk-engines-2.18.2-change-bullet.patch

gtk2-engines.spec
tooltips.patch

安裝 SRPM 套件

[dywang@dywH rpmbuild]$ rpm -ivh gtk2-engines-2.18.4-5.el6.centos.src.rpm

查看程式主要的打包壓縮檔。

[dywang@dywH rpmbuild]$ cd SOURCES/
[dywang@dywH SOURCES]$ ls gtk-engines-2.18.4.tar.bz2 
gtk-engines-2.18.4.tar.bz2

切換到暫存目錄，不安裝 rpm 檔下抽取 rpm 檔，做為修改前後之比較。

[dywang@dywH tmp]$ rpm2cpio ../gtk2-engines-2.18.4-5.el6.centos.src.rpm | cpio -idvm
gtk-engines-2.18.2-change-bullet.patch
gtk-engines-2.18.4.tar.bz2
gtk2-engines.spec
tooltips.patch

暫存目錄下解開 gtk-engines-2.18.4.tar.bz2。

[dywang@dywH tmp]$ tar jxvf gtk-engines-2.18.4.tar.bz2

將要修改的 gtkrc 複製到到工作目錄。

[dywang@dywH SOURCES]$ cp ../tmp/gtk-engines-2.18.4/themes/Clearlooks/gtk-2.0/gtkrc mygtkrc

修改 mygtkrc 後將修改前後 patch 存成 gtk-engines-2.18.4-gtkrc.patch。

[dywang@dywH SOURCES]$ vim mygtkrc
[dywang@dywH SOURCES]$ diff -uN ../tmp/gtk-engines-2.18.4/themes/Clearlooks/gtk-2.0/gtkrc mygtkrc \
> gtk-engines-2.18.4-gtkrc.patch

修改預設顏色。

修改 RPM spec 規格檔版本加入 dyw，且將 gtk-engines-2.18.4-gtkrc.patch 設定為 Patch1，原先的 patch1 tooltips 也是修改 gtkrc，因而造成新設定的 patch 出問題，故直接取代 patch1。

建立 RPM 二進位檔，出現相依套件問題，不同的建立環境缺的套件不會相同，必須把缺的套件都安裝起來。

[dywang@dywH SOURCES]$ rpmbuild -ba --clean --target=$(uname -m) ../SPECS/gtk2-engines.spec 
Building target platforms: x86_64
Building for target x86_64
error: Failed build dependencies:
	intltool is needed by gtk2-engines-2.18.4.dyw-5.el6.x86_64

安裝相依套件。

[dywang@dywH SOURCES]$ sudo yum install intltool --enablerepo=centos

再同時建立 RPM 及 SRPM 二進位檔字，成功建立的訊息最後幾行，看到產生三個 RPM 檔及一個 SRPM 檔。

[dywang@dywH SOURCES]$ rpmbuild -ba --clean --target=$(uname -m) ../SPECS/gtk2-engines.spec
