【问题描述】：
我花了数周时间尝试为我的 Panda 板交叉编译 Qt，但没办法，我无法通过 ./configure。如果有人可以帮助我，我将不胜感激。
我的主机系统是 Ubuntu-13.04 ×86_64bit(running un Virtualbox)
我的目标系统是 Pandaboard ES Ubuntu-12.04。
主机箱中的所有步骤：
sudo apt-get install arm-linux-gnueabihf
sudo mkdir /opt/qt-485-armhf
cd /usr/src
sudo wget http://download.qt-project.org/official_releases/qt/4.8/4.8.5/qt-everywhere-opensource-src-4.8.5.tar.gz
sudo tar xf qt-everywhere-opensource-src-4.8.5.tar.gz
cd /usr/src/qt-everywhere-opensource-src-4.8.5
sudo cp -r mkspecs/qws/linux-arm-gnueabi-g++ mkspecs/qws/linux-arm-gnueabihf-g++
sudo vim mkspecs/qws/linux-arm-gnueabihf-g++/qmake.conf
-------------------------------
include(../../common/gcc-base-unix.conf)
include(../../common/g++-unix.conf)
include(../../common/linux.conf)
include(../../common/qws.conf)
#Compiler Flags to take advantage of the ARM architecture
#N.B.:I also tried to uncomment the two following instructions with no success
QMAKE_CFLAGS = -march=armv7-a -mtune=cortex-a9 -mfpu=neon -mfloat-abi=hard
QMAKE_CXXFLAGS = -march=armv7-a -mtune=cortex-a9 -mfpu=neon -mfloat-abi=hard
# modifications to g++.conf
QMAKE_CC = arm-linux-gnueabihf-gcc
QMAKE_CXX = arm-linux-gnueabihf-g++
QMAKE_LINK = arm-linux-gnueabihf-g++
QMAKE_LINK_SHLIB = arm-linux-gnueabihf-g++
# modifications to linux.conf
QMAKE_AR = arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabihf-objcopy
QMAKE_STRIP = arm-linux-gnueabihf-strip
load(qt_config)
---------------------------------
sudo sed -i -e "/#if/d" -e "/#error/d" -e "/#endif/d" config.tests/unix/libmng/libmng.cpp (This command fixes detection of libmng 2.0.)
export QTDIR=/opt/qt4-485-armhf
And finally:
sudo ./configure -prefix /opt/qt4-485-armhf -sysconfdir /etc/xdg -embedded arm -little-endian -host-big-endian -no-qt3support -nomake examples -nomake demos -opensource -confirm-license -release -openssl-linked -no-phonon -no-phonon-backend -no-nis -platform qws/linux-x86_64-g++ -xplatform qws/linux-arm-gnueabihf-g++ -optimized-qmake
With this result:

You have not explicitly asked to use pkg-config and are cross-compiling.
pkg-config will not be used to automatically query cflag/lib parameters for
dependencies
The system floating point format could not be detected.
This may cause data to be generated in a wrong format
Turn on verbose messaging (-v) to see the final report.
OpenSSL support cannot be enabled due to functionality tests!
Turn on verbose messaging (-v) to ./configure to see the final report.
If you believe this message is in error you may use the continue
switch (-continue) to ./configure to continue.
提前致谢。

你为什么不使用 Qt 5？ QWS 的混乱根本不值得处理...... ;-)
-
其实我连QtQuick2都没有提过……另外，软件opengl也适合QtQuick2……

Laszlo：感谢您的回答。我已经在主机和目标机器上都安装了 QT4。我在两者中都成功编译并在本地运行。此外，我已经在主机中安装了也成功编译的 Angstrom arm 工具链，但是编译后的应用程序未在目标机器中运行，它退出时出现未找到文件的消息，我认为出现问题是因为 angstrom 工具链适用于 gnueabi 和 OMAP4430需要 gnueabihf，因此我正在尝试在我的主机箱中构建一个 gnueabihf 工具链。

还有一点，奇怪的是你使用
gnueabihf，其中hf应该代表硬件浮动，然后是-mfloat-abi=softfp
