Installing wxWidgets on Ubuntu

The latest download and install instructions are available in
https://docs.wxwidgets.org/3.1/plat_gtk_install.html
The wiki is a bit old so try following the above and consult the wiki for more details. BUT, follow the steps as per the docs NOT the wiki.
https://wiki.wxwidgets.org/Compiling_and_getting_started

However sometimes specially for new linux users it can become overwhelming and installation process can throw funny errors. So I have created a step by step process to hopefully help you compile wxwidgets. Enjoy :-)

Installing pre-requisites

sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev
sudo apt-get install libgtk-3-dev
sudo apt-get install mesa-utils
sudo apt-get install freeglut3-dev
sudo apt-get install -y libjpeg-dev
sudo apt-get install liblzma-dev

Download latest release file from github

curl -LJO https://github.com/wxWidgets/wxWidgets/releases/download/v3.0.5/wxWidgets-3.0.5.tar.bz2

Unpack and configure for compilation

tar -xvf wxWidgets-3.0.5.tar.bz2 -C wxWidgets
cd wxWidgets-3.0.5/
mkdir gtk-build
cd gtk-build
../configure  --with-gtk=3 --with-opengl

--with-opengl allows for use of opengl with wxwidgets

Make Sources

make -j3 

install wxwidgets

sudo make install

install library

On some systems you need to rebuild the library cache and make sure your new library is found everywhere in the system. Its a bit like registering a DLL in Windows. Its required on Ubuntu.

sudo ldconfig

Test installation

wx-config --list
wx-config --version             // e.g. yields "3.0.5"

Test by building samples

cd samples/minimal            // assumes you are still in gtk-build directory
make
./minimal

Clean install folder

Cleaning the build folder will remove the build intermediates and so you wont be able to say re-make the samples inside the gtk-build directory.

make clean

Thankyouuuu
