Build Emacs 23 on Ubuntu 6.06 LTS

1. Packages to be installed before build Emacs
sudo aptitude install build-essential libxpm-dev libungif4-dev libtiff4-dev libjpeg-dev libgtk2.0-dev xaw3dg-dev libdbus-glib-1-dev libgpmg1-dev libgnome-dev libotf-dev

2. Configure and make Emacs
tar axf emacs-23.3.tar.bz2
mkdir bld
cd bld
../emacs-23.3/configure --without-pop --with-x-toolkit
make

3. The result (click to see the rendering of TrueType font)

4. If only console mode Emacs is needed, configure and make Emacs as
tar axf emacs-23.3.tar.bz2
mkdir bld
cd bld
../emacs-23.3/configure --without-x
make

我的需求，有人聽到了

而且還做好了：

自己編的 library 無法被系統使用

在使用 Ubuntu 時，有些自己編的 library DSO 沒有辦法被系統自動引用，解法是先把要加入 library search path 的路徑加入 /etc/ld.so.conf，再使用 ldconfig 來重建 DSO 的搜尋 cache。

$ tmux

tmux: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

$ cat /etc/ld.so.conf

/usr/local/lib

$ sudo ldconfig -v

$ tmux
