MeeGo uses RPM as the package format. After you finish your application development work, you need to make a RPM package to publish it. This page will introduce a tutorial to create RPM package with MeeGo SDK and tools. To generate MeeGo adapted RPM packages, the MeeGo Packaging Guideline should be followed. This page will provides a simple tutorial to create a MeeGo rpm package for an OpenGL application called "textures", which is an example in Qt demo.
The textures is one example of Qt demo and included in qt-examples package. The project is at /usr/lib/qt4/example/opengl/textures.
cp -a /usr/lib/qt4/example/opengl/textures $workspace/textures-0.0.1
cp images/side6.png textures.png
vi textures.desktop
with following contents:
[Desktop Entry] Name=QtDemoTextures Comment=Qt Demo Textures Exec=textures Categories=System; Icon=textures Type=Application Terminal=false StartupNotify=true
HEADERS = glwidget.h \
window.h
SOURCES = glwidget.cpp \
main.cpp \
window.cpp
RESOURCES = textures.qrc
QT += opengl
# install
#target.path = $$[QT_INSTALL_EXAMPLES]/opengl/textures
#sources.files = $$SOURCES $$HEADERS $$RESOURCES $$FORMS textures.pro images
#sources.path = $$[QT_INSTALL_EXAMPLES]/opengl/textures
target.path = /usr/bin
icon.files = textures.png
icon.path = /usr/share/icons
desktop.files = textures.desktop
desktop.path = /usr/share/applications
INSTALLS += target icon desktop
qmake make make install
make distclean cd .. tar jcvf textures-0.0.1.tar.bz2 textures-0.0.1
MeeGo recommends to use Spectacle to either create MeeGo spec file or convert existing spec file to MeeGo spec file.
yum install spectacle
Note: An known issue is you also need to install python-cheetah in MeeGo 1.0 SDK chroot
yum install python-cheetah
Spectacle uses a package meta-data file as the input to generate MeeGo spec file. The meta-data file is in YAML format. Spectacle defines specific Syntax of Spectacle YAML.
vi $workspace/textures.yaml
with following contents:
Name: spectacleName: textures Summary: Qt Demo - OpenGL Textures Version: 0.0.1 Release: 1 Group: Applications/System License: LGPLv2.1 URL: http://qt.nokia.com Sources: - "%{name}-%{version}.tar.bz2" Description: Qt Demo OpenGL Textures
PkgConfigBR:
- QtCore >= 4.6.0
- QtOpenGL
- QtGui
Configure: none
Builder: none
Files:
- /usr/bin/textures
- /usr/share/application/*.desktop
- /usr/share/icons/*.png
spec2spectacle package_name.spec
With the YAML file, the spec file can be easily generated:
specify textures.yaml
The generated $workspace/textures.spec file is:
# # Do not Edit!

Note: In textures.yaml, we put "none" for the "Builder" option since the spectacle v0.15 does not support qt build well so we have to manually change the textures.spec. That limitation has been fixed in latest spectacle, which however is not included in MeeGo 1.0.
# >> build pre export PATH=$PATH:/usr/lib/qt4/bin qmake-qt4 # << build pre
# >> install post
make INSTALL_ROOT=%{buildroot} install
# << install post
For application developers, they may want to create package directly from the MeeGo SDK chroot environment. It's quite easy to use rpmbuild to do that.
yum install rpmbuild yum install meego-rpm-config
cp textures-0.0.1.tar.bz2 ~/rpmbuild/SOURCES/ cp textures.yaml ~/rpmbuild/SOURCES/ cp textures.spec ~/rpmbuild/SPECS/
cd ~/rpmbuild/SPECS rpmbuild -ba textures.spec
Then the rpm packages will be generated at:
~/rpmbuild/RPMS/i586/textures-0.0.1-1.i586.rpm ~/rpmbuild/SRPMS/textures-0.0.1-1.src.rpm
cd ~/rpmbuild/RPMS/i586/ yum localinstall --nogpgcheck textures-0.0.1-1.i586.rpm
Then you can start the MeeGo SDK simulator and find QtDemoTextures in applications->System Tools. Click it and run.
For people who do build or release, they may just want to build packages without the MeeGo SDK chroot environment. The following steps are useful for them.
Under Linux, a tool called "build" is used to create rpm packages directly from spec file.
* MeeGo * Fedora 10,11,12 * openSUSE(s) * xUbuntu 8.10/9.04/9.10 * Debian 5.0
sudo build --repository http://repo.meego.com/MeeGo/release/1.0/core/repo/ia32/os/ --arch i686 spectacle.spec
The packages will be generated at /var/tmp/build-root/home/abuild/rpmbuild/RPMS/ and /var/tmp/build-root/home/abuild/rpmbuild/SRPMS/ You may configure your http_proxy to make sure the repo can be accessed.
export http_proxy=http://proxy_server:port
