为 Pandaboard 交叉编译 Qt [英] Cross-compiling Qt for Pandaboard

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.如果有人能给我帮助，我将不胜感激.

I spend weeks trying to cross compile Qt for my Panda board and no way, I can't pass the ./configure. If someone could give me a help I'll appreciate.

我的主机系统是 Ubuntu-13.04 ×86_64bit(在 Virtualbox 上运行)

My host system is Ubuntu-13.04 ×86_64bit(running un Virtualbox)

我的目标系统是 Pandaboard ES Ubuntu-12.04.

My target system is 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.

推荐答案

要在 PC 上交叉编译程序，您必须具有相同包的 development 文件安装在 PC 上作为 ARM 目标.Qt 4.8依赖于OpenSSL，所以如果你想编译Qt，你必须获得ARM版本的正确开发文件em>.

To cross-compile a program on a PC you must have the development files for the same packages installed on the PC as the ARM target. Qt 4.8 depends on OpenSSL, so you must get the correct development files for the ARM release if you wish to compile Qt.

1. 安装 Ubuntu 12.04 PC 虚拟机.与董事会版本相同.
2. 获取编译器.apt-get install arm-linux-gnueabihf(你知道的).
3. 获取所需的开发包.apt-get install libssl-dev 或
   apt-get build-dep -aarmhf qt4(仅适用于 X11).
4. 编辑您的 Qt 配置以满足您的需求并构建它.

1. Install a Ubuntu 12.04 PC virtual box. SAME VERSION as the board.
2. Get the compiler. apt-get install arm-linux-gnueabihf (You knew that).
3. Get required development packages. apt-get install libssl-dev or
   apt-get build-dep -aarmhf qt4 (which only works for X11).
4. Edit your Qt configuration to suit your needs and build it.

您缺少的当前步骤是步骤 3；但是要执行它，您需要步骤 1 或其他一些方法来获取 Ubuntu 12.04 的 OpenSSL 开发文件.使用 apt.sources 可能还有其他方法可以做到这一点.我认为以上步骤对您来说是最简单的.

The current step you are missing is step 3; but to perform it you need step 1 or some other way to get the OpenSSL development files for Ubuntu 12.04. There is probably some other way to do this using apt.sources. I think the steps above will be easiest for you.
