build 32bit app on ubunt12.04 64bit

some tips to build a 32bit app on ubuntu 12.04 64bit

1. edit terminal setting
sudo rmdir /usr/share/terminfo
sudo ln -s /lib/terminfo /usr/share/terminfo

2. change shell to bash ( dash is default shell for utuntu 12.04 )
sudo rm /bin/sh
sudo ln -s /bin/bash /bin/sh

3. install packages ( especially ia32-lib and libc6-dev-i386 )
sudo apt-get install automake autoconf ia32-libs zlib1g-dev bison flex libtool gawk libc6-dev-i386

Memo - Scanner and Vuescan 9 settings

Vuescan 9

Before scanning films:
1. build up scanner icc profile (IT8/Q60)
2. find out film base under "positive film" and "scanner profile"

Scanning:
1.INPUT: positive film + lock filmbase + mulit-exposure + multi-scanning ( 2 times is enough, I don't see the big different between 2 and 16 times. This also keep the scanner life longer :D )
2.COLOR: film base (red, green, blue ) + scanner icc profile
3.OUTPUT: 48bit RGB RAW
4.Preview
5.CUT: adjust positions
6.Scan
7.adjust curves ( white and black ) in PhotoShop or Photo Elements
8.run ColorNeg transfer
