93.82.13.28: set PREFIX in install section

{{MADDE}}

===Introduction===
This guide explains how to take a simple [[Qt-Maemo|Qt]] application and compile it so that it deploys to the [[Nokia N900|N900]] with an Icon. It is supposed to be step by step guide on how to take a (simple) Qt app and package and deploy it with an Icon using [[MADDE]].

=== Prerequisites ===

The project I have is simple, 1 window called mainwindow.

'''Note:''' As a convention I like to keep all my code together, so I have created any extra files in the "src" folder.

=== Steps ===
1. Create simple project through MADDE.
mad pscreate -t qt_simple projectname

2. Edit and test with QT Creator (or whatever your favorite tool is).

3. Once ready to deploy create a clean empty top level folder "<projectname>-0.x" where x is your revision number e.g. "c:\Madde\0.5\home\shep\wwcalc-0.1"...In the OS
'''Note: the following 3 steps apply each time you go to build.'''
3.1 ensure there is no "debian" folder at the same level as "src"
3.2 ensure there is no folder structure called "<projectname>-0.x-orig" left over from a failed compile
3.3 remove old compiles from the Madde\home\user (e.g. C:\Madde\0.5\home\Shep) folder.

4. Copy the "src" folder from the tested Qt project into the "<projectname-0.x" folder

5. Create (or obtain) an application Icon. This should be a 64x64 PNG. Call it <projectname>.png and place it in the "src" folder.

6. Again inside the "src" folder create a new file called "<projectname>.desktop"
Code:
[Desktop Entry]
Encoding=UTF-8
Version=0.x
Type=Application
Name=<Long Descriptive Project Name>
Exec=/usr/bin/<projectname>
Icon=<projectname>
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable

7. Inside the "src" folder added a file called "src.pro". Getting this right is the key to getting the Makefile correct and hence the install working. At the end of this file there is a section called "INSTALLS += "...for every file you want installed in a location you need an entry here. In the example here we install the target, icon and desktop files.
Code:
TARGET = wwcalc
TEMPLATE = app
SOURCES += qtmain.cpp \
mainwindow.cpp
HEADERS += mainwindow.h
FORMS += mainwindow.ui
PREFIX = ../debian/wwcalc/usr

unix {
PREFIX = /usr
BINDIR = $$PREFIX/bin
DATADIR =$$PREFIX/share

DEFINES += DATADIR=\"$$DATADIR\" PKGDATADIR=\"$$PKGDATADIR\"

#MAKE INSTALL

INSTALLS += target desktop icon64

target.path =$$BINDIR

desktop.path = $$DATADIR/applications/hildon
desktop.files += wwcalc.desktop

icon64.path = $$DATADIR/icons/hicolor/64x64/apps
icon64.files += wwcalc.png
}

8. Up one level and inside the top level folder (i.e. "c:\Madde\0.5\home\<YOU!>\<projectname>-0.x" ) create a file called "<projectname>.pro" with the following exact contents.
Code:
TEMPLATE = subdirs
SUBDIRS = src

10. In Madde make sure the [[MADDE/Device runtime|runtime is up and connectible]] and then execute.
Code:
mad dh_make --createorig --single -e foo.bar@gmail.com -c gpl
*** Several people have commented that mad qmake is not required, but I find there are times that it is, igonre this next line if you wish ***
mad qmake
mad dpkg-buildpackage
mad remote -r org.maemo.<projectname> send ../<projectname>_0.x-1_armel.deb
mad remote -r org.maemo.<projectname> install <projectname>_0.x-1_armel.deb

11. Uninstalling - from an X_Terminal.
Code:
sudo gainroot
dpkg -r <projectname>
