This page will create a MeeGo rpm package from an existing qt project - an OpenGL application called "textures" in qt examples. The original project is just a qt example project and has no icon and can not be launched from MeeGo UI. We will make it more like a stand alone application which can be launched from MeeGo applications panel and create a rpm package which can be installed on MeeGo device.
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/examples/opengl/textures $workspace/textures-0.0.1 cd $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=Development; Icon=textures Type=Application Terminal=false StartupNotify=true
vi textures.pro
The contents will be:
HEADERS = glwidget.h \
window.h
SOURCES = glwidget.cpp \
main.cpp \
window.cpp
RESOURCES = textures.qrc
QT += opengl

#target.path = $$[QT_INSTALL_EXAMPLES]/opengl/textures

MeeGo recommends to use Spectacle to either create MeeGo spec file or convert existing spec file to MeeGo spec file.
yum install python-cheetah yum install spectacle
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 the following content:
Name: textures
Summary: Qt Demo - OpenGL Textures
Version: 0.0.1
Release: 1
Group: Development/Tools
License: LGPLv2.1
URL: http://qt.nokia.com
Sources:

Description: Qt Demo OpenGL Textures
PkgConfigBR:

- QtGui
Configure: none
Builder: none
Files:
- "%{_bindir}/textures"
- "%{_datadir}/applications/*.desktop"
- "%{_datadir}/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:

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 -set install_prefix %{_prefix}
qmake

# >> 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.
zypper install rpmbuild zypper 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
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 textures.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
The rpm package can be installed on MeeGo devices or MeeGo SDK simulator directly. Copy the rpm to target device or simulator and run:
yum localinstall --nogpgcheck textures-0.0.1-1.i586.rpm
Then you can find QtDemoTextures in applications->Programming. It's ready to be distributed.
