> tar -xvzf libxml2-sources-2.7.8.tar.gz

> cd libxml2-2.7.8

> ./configure --prefix=/home/work/dist --without-python

> make

> make install

=== zlib ===

> wget http://www.zlib.net/zlib-1.2.5.tar.gz
> tar -xvzf zlib-1.2.3.tar.gz
> cd zlib-1.2.3.tar.gz
> ./configure --prefix=/home/work/dist
> make
> make install

=== glib ===

1. 下載(http://www.icewalkers.com/Linux/Software/515980/GLib2.html) glib2.0_2.30.1.tar.bz2

> apt-get install libffi-dev, gettext

> tar -xvjf glib2.0_2.30.1.tar.bz2

> cd glib2.0_2.30.1
>./configure --prefix=/home/work/dist CFLAGS="-I/home/work/dist/include -L/home/work/dist/lib" glib_cv_stack_grows=no glib_cv_uscore=no ac_cv_func_posix_getpwuid_r=yes ac_cv_func_posix_getgrgid_r=yes ac_cv_lib_rt_clock_gettime=no glib_cv_monotonic_clock=yes

> make

> make install  

=== gstreamer ===

1. 下載(http://gstreamer.freedesktop.org/src/gstreamer/)gstreamer-0.10.35.tar.gz

> sudo apt-get install bison flex
> export PKG_CONFIG_PATH=/home/work/dist/lib/pkgconfig
> ./configure --prefix=/home/work/dist CFLAGS=-I/home/work/dist/include --disable-registry  --disable-gtk-doc ac_cv_func_register_printf_function=no --disable-tests --disable-valgrind --disable-debug --disable-gst-debug 
> make && make install  

== gst plugin base ===

1. 下载(http://gstreamer.freedesktop.org/src/gst-plugins-base/)gst-plugins-base-0.10.35.tar.gz

> export PKG_CONFIG_PATH=/home/work/dist/lib/pkgconfig

> ./configure --prefix=/home/work/dist CFLAGS=-I/home/work/dist/include --disable-valgrind --disable-gnome_vfs --disable-alsa  --disable-pango --disable-theora --disable-examples

> make && make install  

=== qt ===

1. 先裝 libX11-dev、libXext-dev、libXtst-dev、libqglviewer-dev、libmysql++-dev、g++ 等開發工具包（sudo apt-get install ....）
2. 修改 configure，加上"PKG_CONFIG_PATH=/home/work/dist/lib/pkgconfig"
3. 記得在 configure 的眾多參數當中，加上 -force-pkg-config
4. 在 qt-XXX-4.8.0/src/3party/webkit/Source/WebKit.pro 加上 LIBS += -L/home/work/dist/lib
5. 大概建議用這樣的參數

> export PKG_CONFIG_PATH=/home/work/dist/lib/pkgconfig
> sudo ./configure -qt-libmng -qt-zlib -qt-libtiff -qt-sql-mysql -qt-libpng -qt-libjpeg -no-qt3support -webkit -force-pkg-config -opengl -prefix /opt/qt-4.8.0 -nomake examples -nomake demos -nomake docs

在 Mac 上build Qt

./configure -sdk /Developer/SDKs/MacOSX10.6.sdk -opensource -universal

很多東西不是用來賣的

賣而不賣、不賣是賣

舉個例子，如果 Google 當初設定的目標，是搜尋費用，那麼 Google 應該只能成為歷史名詞
