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，我创建了自己的 mkspec 文件 linux-TIarmv7-g++，其配置如下：
> #
> # qmake configuration for building with arm-linux-g++
> #

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

> #Toolchain

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 -no-accessibility -no-openssl -no-gtkstyle -qt-mouse-pc -qt-mouse-linuxtp -qt-mouse-linuxinput -插件-鼠标-linuxtp -插件-鼠标-pc -fast -confirm-license -v
在执行和详细之后，我得到以下错误：与 freetype 库相关

如何解决这个错误？
