QT4.8.1移植到ARM目标板

上一篇 ： [交叉编译qt4.8.4 for ARM]遇到到问题

1. 在此基础上，将交叉编译好的qt4.8.1-for-arm移植到目标板：

进入/usr/local/qt4.8.1-for-arm,对嵌入式qt进行打包，复制到目标板的相同目录下，可以通过minicom进行。

(参考：http://www.linuxidc.com/Linux/2013-04/82384p2.htm)

2. 在主机上交叉编译一个最简单到hello目标程序，通过nfs方式，在目标板上执行，出现错误：

root@freescale /mnt/nfs/hellow$ ./hellow

QFontDatabase::loadFromCache: Font path doesn't match. Found /usr/lib/fonts in database, expected /usr/local/qt-4.8.1-for-arm/lib/fonts

Aborted

实际上这两个路径都存在，而且内容也一样，如下附部分。

解决办法：参考 http://blog.csdn.net/g457499940/article/details/11902045
目标板终端执行env或export查看环境配置，在/etc/profile中添加下面一行，将QT_QWS_FONTDIR环境变量export成前面一个路径，

export QT_QWS_FONTDIR=/usr/lib/fonts

保存之后，执行source /etc/profile

问题解决。
