Develop, test, run your application on Linux desktop, and deploy on Rasberry Pi2 board, x86_64 and other Linux machine.....
Cross compiler application development for Raspberry Pi is now available for Linux. This ide/toolchain known to work and already tested on Ubuntu 14.04-LTS Trusty Tahr.

wget https://raw.githubusercontent.com/dveltool/toolchain/master/installer/dveltool_installer.sh
chmod 755 dveltool_installer.sh
./dveltool_installer.sh

For installation packages, please check on following url:

https://github.com/dveltool/toolchain

Toolchain is generated using awesome build system called buildroot, and make use of prominent eclipse ide.

Please make try this application, and would like to hear your feedback ....

How to Build wxWidgets / C++ for Raspberry Pi Model 2 (ARMv7 Architecture). 

UPDATED:

For ease to install and configure Eclipse-IDE/Toolchain, use following link of ready used installer:

http://yasriady.blogspot.co.id/2016/01/raspberry-pi-toolchain.html

wxWidgets is an awesome C++/GUI library to work with. It can produce very nice desktop interface and has complete class library either for GUI on non GUI. Binary program yields by this library is also small and portable. Statically linking is possible to make the program running independently to any linux distribution.

Raspberry Pi is credit card sized computer, it has small form factor with capability similar to PC of PIII/900MHz with 1GB RAM. Thus, sufficient to running desktop application, as in his case, Raspbian Wheezy.

Here, you will find brief tutorial how to build wxWidgets for Raspbian to run on Raspberry Pi model 2 (ARMv7 processor).

Setup environment to used are:

• Build system on Ubuntu 14.04 LTS x64
• buildroot
• wxWidgets-3.0.2
• Target: RaspberryPi2 and Raspbian Wheezy

Build Toolchain for ARMv7

To build cross architecture Toolchain we can use awesome build system called buildroot (http://buildroot.uclibc.org/)

$ cd ~
$ mkdir wxWidgets
$ cd ~/wxWidgets
$ git clone git://git.buildroot.net/buildroot
$ cd buildroot
$ make raspberrypi2_defconfig
$ make menuconfig

Adjust some requirement as follow:

    Toolchain
    C library (uClibc) --->
    (X) glibc

    Target packages > Graphic libraries and applications
    [*] X.org X WIndow System --->

    Target packages > Libraries > Graphics
    [X] libgtk2

    [Save]

$ make

Build wxWidgets for ARMv7

Once above toolchain baked and cooked well, then we can start to build and compile wxWidgets and it’s sample application.

$ export PATH=~/wxWidgets/buildroot/output/host/usr/bin:$PATH
$ cd ~/wxWidgets
$ wget http://nchc.dl.sourceforge.net/project/wxwindows/3.0.2/wxWidgets-3.0.2.tar.bz2
$ tar -xzpvf wxWidgets-3.0.2.tar.bz2
$ cd wxWidgets-3.0.2
$ mkdir -p build_rpi2/wx3.0.2u_static
$ cd build_rpi2/wx3.0.2u_static
$ ../../configure --host=arm-linux --with-gtk --with-libpng=builtin --with-libjpeg=builtin --with-libtiff=builtin --with-regex=builtin --with-zlib=builtin --with-expat=builtin LDFLAGS="-static-libgcc -static-libstdc++"
$ make 

Sit back and relax...... 

Build Sample Application

$ cd samples/minimal
$ make

Copy sample/minimal/minimal to Pi's sdcard and from there try to run: 
$ ./minimal

See the result ................

After adjusting some path as describe on buildroot manual, you can download ready  used Raspberrypi-Toolchain on sourceforge.net. The  toolchain already tested on Ubuntu 14.04 with wxWidgets-3.0.2 as target built. This toolchain can be used for compiling Plain C/C++ for Pi application.

Build wxWidgets Application to Run on Any Linux

Link wxWidgets application statically and run on any linux distribution without missing any dependency files.

This tutorial inspired by article written by Tierra here, mentioned about linking with gtk and run on any linux. Also to show you how to make static linking to libstdc++ since various linux distribution will have different version of this library that could lead to error program to running.

Note: Remember that GTK is licensed under LGPL, which essentially means that in order to link it to your application _statically_, your application will have to be (L)GPL-licensed.

$ sudo mkdir -p /opt/wxWidgets
$ cd /opt/wxWidgets
$ wget http://ftp.wxwidgets.org/pub/3.0.2/wxWidgets-3.0.2.tar.bz2
$ tar -xapvf wxWidgets-3.0.2.tar.bz2
$ cd wxWidgets-3.0.2
$ mkdir -p build2/wx3.0.2u_static

$ cd build2/wx3.0.2u_static
$ ../../configure --disable-shared --with-gtk --with-libtiff=builtin --with-libjpeg=builtin --with-libpng=builtin --with-regex=builtin --with-zlib=builtin --with-expat=builtin LDFLAGS="-static-libgcc -static-libstdc++"
$ make 

Note: using similar switch as shown at autoconf above , you may also build/compile any Plain C/C++ application to link statically.

GUI Designer for wxWidgets using wxFormBuilder

GUI Designer for wxWidgets using wxFormBuilder

  4:07 PM    Dedy Yasriady

---

I used wxFormBuilder frequently in recent years as GUI Designer when coding with wxWidgets. This RAD tools very much help programmer to build GUI up and running in a snap. Following tutorial will guide you in quick simple steps to configure and work with wxFormBuilder.

Installing wxFormBuilder in Ubuntu

$ sudo apt-get install libwxgtk3.0-0 libwxgtk-media3.0-0

$ sudo add-apt-repository -y ppa:wxformbuilder/release
$ sudo apt-get update

$ sudo apt-get install wxformbuilder

Installing wxFormBuilder in Windows

Get download wxFormBuilder_v3.5.1-rc1.exe

Work with the Tools, Begin wxFormBuilder

Starting the program and you will be greeted with new blank project with MyProject1 as an intial name.

For easy associating with the UI naming, then I would like to alter this name into UI. Take a look at Object Properties on the right pane, and make change to this properties:

name : UI
file : UI

Then save the project into your netbeans project (let say into folder wxApp) and make the name UI.fbp

Adding Frame

Activate tab [Forms], then select/click Frame to insert it into project and adjust properties: 

name : MainFrame
title : My wxApp

You basic GUI is now ready and to make a test, just press [F5]

Working with Window Controls

To enrich the GUI and to have full featured application  window, you may can follow the step below:
Adding layout:

[Layout] + wxFlexGridSizer
Properties :
growablecols : 1

Adding Label or StaticText

[Common] + wxStaticText
Properties :
label : What is your name:

Adding TextControl

[Common] + wxTextCtrl
Properties :
flag : wxEXPAND [v]

Adding Spacer

[Layout] + spacer

Adding Button

[Common] + wxButton
Properties :
flag : wxALIGN_RIGHT [v]

Preview the Window, press [F5]

Generate C++/wxWidgets codes

After make a GUI design, you may then generate C++ code, just press :
[F8] to Generate base class and yield you with 2 files UI.cpp and UI.h. PLEASE DO NOT make any MODIFICATION directly to these files
[F6] to Generate Inherited Class inside the files UIMainFrame.cpp and UIMainFrame.h, on which you will work with directly

Complete File is Here !

Get fresh wxApp from my Github repository, clone to your local folder and try to figure out the files inside this netbeans projects.

Happy coding …………………… / Ddy
