Qt配置freetype错误

Question

我正在尝试为ARM cortex 8板构建QT。

我按照给定的说明成功安装了主机配置：http://qt-project.org/wiki/Building_Qt_for_Embedded_Linux

在ARM板目标构建配置时，我已经创建了自己的mkspec文件linux-TIarmv7-g++，其配置如下：

> #

> #

> include(../../common/g++-unix.conf) include(../../common/linux.conf)

我已经安装了codesourcery工具链，我的环境是Ubuntu 12.04 64位操作系统，目标板是ARM-cortex8

我的配置如下：

./configure -prefix /usr/local/qt-embedded -embedded arm -platform qws/linux-x86_64-g++ -xplatform qws/linux-TIarmv7-g++ -depths 16,24,32 -no-mmx -no-3dnow -no-sse -no-sse2 -no-glib -no-cups -no-largefile文件-no-可访问性-no-openssl -no-gtkstyle -qt--prefix-pc-qt-linuxtp-qt--depths-linuxinput-plugin-mouse linuxtp-plugin-mouse pc -fast -confirm-license -v

执行并详细后，我得到以下错误:与freetype库相关

如何解决这个错误？

Answer 1

似乎还没有安装freetype开发库。

sudo apt-get install libfreetype6-dev能解决你的问题吗？
