准备
主机平台：Ubuntu 16.04 LTS(x64)
目标平台：ARM40-A5D3
Qt版本：Qt4.8.7
tslib github
ARM-GCC编译工具链：gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi
交叉编译工具链
下载gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi.tar.xz

安装ARM-GCC编译工具链
$ sudo xz -d gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi.tar.xz
$ ls
$ sudo tar xvf gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi.tar -C /opt/

编辑.bashrc文件
$ cd ~
$ vim .bashrc

在.bashrc的末尾添加下面的文本
export PATH=$PATH:/opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi/bin/
查看ARM-GCC版本
$ arm-linux-gnueabi-gcc -v

Thread model: posix
gcc version 4.9.4 (Linaro GCC 4.9-2017.01)
安装tslib
使用浏览器下载tslib
下载tslib
使用git下载tslib
$ sudo apt-get install git
$ git clone https://github.com/kergoth/tslib.git

正克隆到 ‘tslib’…
remote: Counting objects: 5089, done.
remote: Total 5089 (delta 0), reused 0 (delta 0), pack-reused 5089
接收对象中: 100% (5089/5089), 2.39 MiB | 429.00 KiB/s, 完成.
处理 delta 中: 100% (3505/3505), 完成.
检查连接… 完成。
编译tslib
$ sudo apt-get install automake libtool
$ sudo mkdir /opt/tslib
$ cd tslib
$ ./autogen.sh
$ ./configure CC=arm-linux-gnueabi-gcc \
CXX=arm-linux-gnueabi-g++ \
--prefix=/opt/tslib \

编译报错
/home/jonny/tslib/libtool: line 10540: arm-linux-gnueabi-gcc: command not found
libtool: error: error: relink ‘linear.la’ with the above command before installing it
Makefile:755: recipe for target ‘install-pluginexecLTLIBRARIES’ failed

make1: Leaving directory ‘/home/jonny/tslib/plugins’

make: * [install-recursive] Error 1
解决方案
原因：sudo命令使用的是root的环境变量，sudo就找不到ARM-GCC了
解决：添加ARM-GCC的绝对路径就好了
$ ./configure CC=/opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc \
CXX=/opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi/bin/arm-linux-gnueabi-g++ \

编译Qt4.8.7
下载qt-everywhere-opensource-src-4.8.7.tar.gz

解决方案：一般都是编译器路径有问题导致的，检查qmake.conf文件
查看Qt版本
$ cd /opt/qte4.8.7/bin/
$ ./qmake -v

QMake version 2.01a
Using Qt version 4.8.7 in /opt/qte4.8.7/lib
至此，Qt4.8.7交叉编译完成。
