本文介绍如何在Linux系统中安装和配置MeeGo 1.1 SDK。
Contents |
准备/约定
- 硬件: 任一较新款的处理器, 比如32位的Intel Atom 或者 Intel Core 2 CPU. 为使用QEMU 需要将MeeGo运行在虚拟机中，为此你的系统必须支持虚化技术 (术语Virtualization Technology,或者说VT). 清参考图形加速获取更多信息.
- 软件: MeeGo 1.1 SDK 已经在32位Fedora 12, [Fedora 13, Ubuntu 9.10, 和 Ubuntu 10.04 LTS进行验证. 对于其它主机操作系统的支持情况请访问this page.
- Root 权限: 安装 SDK 需要你具备root权限. 在执行需要root权限的命令时，通常都会在命令前冠以"sudo"的前缀. 为了方便, 最好为你的登录用户增加可以执行"sudo"命令的权限，这样可以方便的在root权限和普通用户权限之间进行切换,(可参考 sudo的帮助页.)
- 命令: 本文给出的命令例子都会以"$"指示."$"不是命令的一部分，在终端输入命令时请不要输入字符"$".
为你的发行版配置软件库安装源
针对Ubuntu或Debian平台
- 将下面文本行加入到
/etc/apt/sources.list.d/meego-sdk.list中.
根据你的操作系统和版本，将${distribution}/${version}替换成以下字串: "debian/5.0", "ubuntu/09.10", "ubuntu/10.04" or "ubuntu/10.10".deb http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/ / - 为软件仓库增加公钥:
$ gpg --keyserver pgpkeys.mit.edu --recv 0BC7BEC479FC1F8A $ gpg --export --armor 0BC7BEC479FC1F8A | sudo apt-key add -
- 更新软件源:
$ sudo apt-get update
- 如想测试软件源是否正确被添加, 请运行以下命令测试. 正常的情况会在屏幕上打印出MADDE包的详细信息.
$ apt-cache policy madde
针对Fedora平台
- 进入yum软件源配置目录:
$ cd /etc/yum.repos.d/
- 增加MeeGo SDK的yum软件源.
根据你的Fedora版本将下面命令中的${distribution}/${version}替换成相应的: "fedora/12" 或 "fedora/13".$ sudo wget http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/meego-sdk.repo - 安装签名公钥:
$ sudo rpm --import http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/repodata/repomd.xml.key - 更新软件包数据库:
$ sudo yum update
针对MeeGo平台
- To add the MeeGo SDK repository on a system running MeeGo, run the following command.
Replace ${distribution}/${version} with one of the following values: "meego/1.1" or "meego/trunk".$ sudo zypper addrepo -f http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/meego-sdk.repo
针对openSUSE平台
- To add the MeeGo repository, run the following command.
Replace ${distribution}/${version} with one of the following values: "opensuse/11.2" or "opensuse/11.3".$ sudo zypper addrepo -f http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/meego-sdk.repo
安装 MeeGo SDK
- Debian / Ubuntu
$ sudo apt-get install meego-sdk
- Fedora
$ sudo yum install meego-sdk
- OpenSUSE / MeeGo
$ sudo zypper install meego-sdk
只装ARM版本的:
- Debian / Ubuntu
$ sudo apt-get install meego-sdk-armv7l
- Fedora
$ sudo yum install meego-sdk-armv7l
- OpenSUSE / MeeGo
$ sudo zypper install meego-sdk-armv7l
只装IA32版本的:http://wiki.meego.com/SDK/Docs/1.1/Configuring_QEMU_runtimes
- Debian / Ubuntu
$ sudo apt-get install meego-sdk-ia32
- Fedora
$ sudo yum install meego-sdk-ia32
- OpenSUSE / MeeGo
$ sudo zypper install meego-sdk-ia32
安装MeeGo目标机交叉编译环境
所谓 目标机交叉编译环境是用于编译MeeGo程序所需要的交叉编译工具和开发库(sysroot). 下载下来后是一个很大的(大约250MB).bz2格式的文件. MADDE (MeeGo应用开发和调试环境的缩写,(background)) 是一个用于帮助下载和安装目标交叉编译环境的工具集。"mad-admin"是MADDE的一个命令行工具. 你可以安装多个目标机交叉编译环境（比如针对arm的和针对x86的）并在Qt Creator中切换它们（会在后头介绍）.
- Create a MeeGo target using MADDE
Run the command below. Replace <target> with one of- meego-core-armv7l-1.1.2: Build applications for ARM handheld devices (such as N900)
- meego-handset-ia32-1.1.2: Build applications for x86 handheld devices (such as Aava)
- meego-netbook-ia32-1.1.2: Build applications for x86 netbooks.
-fflag instructs MADDE to download the Target tarball (bz2) first.$ sudo mad-admin create -f <target>
If you encounter problems, check the Troubleshooting page
- To check that the target has been installed correctly, run the following.
Replace <target> with one of the values described in the previous step$ mad -t <target> pscreate -t qt-simple qthello $ cd qthello $ mad -t <target> qmake $ mad -t <target> make
Note: Running qmake will print "-unix is deprecated" This is not an error with the compilation. You can safely ignore this for now.
- To check that the qt-simple application is created for the correct target, run:
$ file build/qthello
安装MeeGo运行时环境
运行时环境指的是在主机系统上调试应用时运行在QEMU中的MeeGo操作系统映像.如果你是在硬件设备上直接调试你的应用，那么你无需安装MeeGo运行时环境。它是一个可通过MADDE下载的.bz文件，大小约为650MB 。在你开始配置Qt Creator之前，运行时环境不会被用到。然而，鉴于下载这个文件得多花点时间，所以还是建议你在开始下面的步骤之前就开始在后台下载安装运行时环境。
可参考 下载运行时环境和使用QEMU
Configuring Qt Creator to use the MeeGo toolchain(s)
Start Qt Creator by selecting Applications > Programming > Qt Creator.
Configure Qt Creator to use the MeeGo toolchain(s):
- Go to Tools > Options > Qt4 > Qt Versions.
- On the right side of the Qt Versions view, click on the plus sign button to add a new version.
- A blank, new version appears in the Qt Versions view.
- On the Version Name line, specify a name for the new version.
- On the qmake location line, specify a qmake location for the new version. The toolchain installs by default to
usr/lib/madde/linux-i686/targets/<target>/bin/qmake. - Click Rebuild, Apply and OK.
Using the MeeGo SDK Qt version
It is also possible to use Qt Creator without a MeeGo toolchain. This option can be useful if you don't need to cross-compile your software: for example, if you are doing QML development with no use of C++.
The steps are the same as above, but the qmake location is set to the qmake installed with the meego-sdk-qt libraries. The usual location for this on Linux is:
/opt/meego/meego-sdk-qt/bin/qmake
Note: On Ubuntu 10.10, you may need to install g++ in order for this step to work. If necessary, do this:
$ sudo apt-get install g++
使用SDK进行开发
如果你刚刚接触MeeGo SDK,那么hello world 开发指南 是一个不错的起步教程.
该指南涵盖了如何创建一个工程，并进行打包和部署到设备上的各个方面的知识。（这里提到的设备包括真实的设备或者是QEMU运行环境中的一个虚拟设备).
删除／卸载
觉得MeeGo SDK没什么好玩的，你可以按如下方法删除或卸载安装的内容。
针对Ubuntu平台
要删除已安装的软件包,请运行:
$ sudo apt-get remove --purge meego-sdk-qtcreator madde qt-tools arm-2009q1 qemu-arm qemu-gl meego-sdk-i586-toolchain meego-qemu meego-sdk-qt
要删除安装这些包时安装的依赖包，请运行:
$ sudo apt-get autoremove
要删除整个MADDE目录(在卸载"madde"包的时候，该目录不会被完全删除),请运行:
$ sudo rm -rf /usr/lib/madde
To remove the packages from your local repository (/var/cache/apt/archives/), run:
$ sudo apt-get clean
针对Fedora平台
要删除已安装的软件包,请运行:
$ sudo yum remove meego-sdk-qt-creator madde qt-tools arm-2009q1 qemu-arm qemu-gl meego-sdk-i586-toolchain meego-qemu
要删除整个MADDE目录:
$ sudo rm -rf /usr/lib/madde
针对openSUSE平台
要删除已安装的软件包,请运行:
$ sudo zypper remove -u meego-sdk-qt-creator madde qt-tools arm-2009q1 qemu-arm qemu-gl meego-sdk-i586-toolchain meego-qemu
要删除整个MADDE目录:
$ sudo rm -rf /usr/lib/madde
