simplify this complex world

“hello word” application, every programmer should always create this kind of application. For desktop application developer, create “hello word” application should be ‘piece of cake’, we can enjoy the sweetness of this ‘piece of cake’ in less then 5 minutes. but now I spend more then 1 day to create my “hello word” application in onyxboox-ebook reader environment. I dont want to lose this knowledge easily so I’ll write my documentation carefully.

Compiler Hardware : lenovo G400
Operating System    : Ubuntu 9.10
==================================

• 1’st Step : Install compiler
  $ sudo apt-get install cmake build-essential
• 2’nd Step : Install the toolchain
  $ cd /tmp
  $ wget http://dev.onyxcommunity.com/sdk/freescale-toolchain.tar.gz
  $ sudo mkdir -p /opt
  $ cd /opt && tar -xvzf /tmp/freescale-toolchain.tar.gz
• 3’rd Step : Downloading example
  $ cd
  $ wget http://dev.onyxcommunity.com/sdk/quickstart.tar.gz
  $ tar -xvzf quickstart.tar.gz && cd quickstart
• 4’th Step : fixing the bug on the source cmakelist file exampe
  $ vim  CMakeLists.txt
  Edit the –> set(ONYXLIBS…. parts from
  set(ONYXLIBS onyx_sys onyx_ui onyx_wifi onyx_wpa)
  to
  set(ONYXLIBS onyx_screen onyx_sys onyx_ui onyx_wifi onyx_wpa)
• 5’th Step : edit the main program on this example
  $vim main.cpp
  ———————————————————————————
  #include <QtGui/QtGui>

  #include “onyx/screen/screen_proxy.h”
  #include “onyx/sys/sys.h”

  int main(int argc, char *argv[])
  {
  QApplication app(argc, argv);
  execl(“/bin/ls”,”ls”);
  QWidget window;
  window.setWindowTitle(“Simple example”);
  QLabel *label = new QLabel (“Hello World!”, &window);
  window.show();
  onyx::screen::ScreenProxy::instance().flush(&window, onyx::screen::ScreenProxy::GC, true,        onyx::screen::ScreenCommand::WAIT_NONE);
  // Tell system manager that it’s not busy now.
  sys::SysStatus::instance().setSystemBusy(false);
  return app.exec();
  }
  ——————————————————————————————————————-

• 6’th Step : Create a simple executable bash file
  $ sudo mkdir output
  $ vim build.sh
  ———————————————————————————————–
  #!/bin/sh

  cd output
  rm -rf *

  cmake -DBUILD_FOR_ARM:BOOL=ON -DCMAKE_VERBOSE_MAKEFILE=ON ..
  make
  ———————————————————————————————-
  $ chmod +x build.sh

• 7’th Step : build the application
  $ ./build.sh

Semestinya sich jalan kalo semua beres 😀
