Raspberry Pi 2 安装最新版FPC和Lazarus 1.5

    2015年2月推出的Raspberry Pi2不能用以前的方法安装Lazarus，当安装fpc时出现下面的问题停止安装。

从http://otapi.com/2015/02/10/raspberry-pi-2-freepascal-lazarus-and-delphi/找到解决方法:

1.安装subversion和unzip

Sudo Apt-get update

Sudo Apt-get install subversion unizp

2.获取和编译最新的FreePascal编译器
Sudo mkdir /usr/local/fpc

cd /usr/local/fpc

Sudo wget -O fpc-2.6.4.arm-linux.tar ?http://sourceforge.net/projects/freepascal/files/Linux/2.6.4/fpc-2.6.4.arm-linux.tar/download

Sudo tar xvf fpc-2.6.4.arm-linux.tar

cd fpc-2.6.4.arm-linux

Sudo ./install.sh

提示安装下列时，输入？后的内容

Install prefix (/usr or /usr/local)? /usr/local

Install textmode IDE(y/n)?y

Install FCL(y/n)?y

Install Packages(y/n)?y

Install Documentation (y/n)?y

Install Demo (y/n)?y

下载最新版FPC：

cd /usr/local/fpc

Sudo svn co ?http://svn.freepascal.org/svn/fpc/trunk trunk

Sudo svn export --force trunk trunktmp

cd trunktmp

编译FPC：

Sudo make all OPT=-dFPC_ARMHF

Sudo make install OPT=-dFPC_ARMHF PREFIX=/usr/local

Sudo make install sourceinstall OPT=-dFPC_ARMHF PREFIX=/usr/local

cd /usr/local/lib/fpc

ls

你在 Terminal应看到最新版本的版本号:

                  2.6.4     3.1.1

用看到最新的版本号替换下面的3.1.1（现最新的版本号为3.1.1） 

Sudo rm -f "/usr/local/bin/ppcarm"

Sudo ln -sf "/usr/local/lib/fpc/3.1.1/ppcarm" "/usr/local/bin/ppcarm"

3.编译及安装最新Lazarus Version

Sudo apt-get update

Sudo apt-get install libx11-dev libgdk-pixbuf2.0-dev libcairo2-dev lpango-1.0 libpangox-1.0-dev xorg-dev

Sudo aptitude install libgtk2.0-dev libgdk-pixbuf2.0-dev libpango1.0-dev

Sudo mkdir /usr/local/lazarus

cd /usr/local/lazarus

Sudo svn co http://svn.freepascal.org/svn/lazarus/trunk trunk

Sudo svn export --force trunk trunktmp

cd trunktmp

Sudo make all OPT=-dFPC_ARMHF

Sudo make install OPT=-dFPC_ARMHF PREFIX=/usr/local

4.最后的设置：

When you first launch Lazarus, it’ll ask for the path to the FPC sources. Enter /usr/local/fpc/trunk then you’re ready to go!

经过长达3小时的安装， Lazarus终于安装完成。

当你第一次启动Lazarus， 要求设置FPC sources，输入 /usr/local/fpc/trunk

编译后的程序运行情况：
