3. Installation

Learn how to install EZ-Draw on GNU/Linux (Ubuntu, Debian, Fedora, etc.), on Mac OS X or Windows, all versions.

3.1. Ubuntu or Debian

First install the development packages: open a terminal and type (or copy-paste):

sudo apt-get install libx11-dev x11proto-xext-dev libxext-dev

Download the file EZ-Draw-1.2.tgz with your web browser, save the file, then move it into your home directory using the file manager. Next, type in the terminal:

tar xvfz EZ-Draw-1.2.tgz
cd EZ-Draw-1.2
make -j all

After a few moments, modules EZ-Draw, demos and games are compiled. To run demo-01, type in the terminal:

./demo-01

and so on for the other demos and games (for instance ./jeu-bubblet or ./jeu-doddle). Next, read the tutorial.

3.2. Fedora

First install the development packages: open a terminal and type (or copy-paste):

sudo yum install gcc libX11-devel libXext-devel xorg-x11-fonts-misc

then type y to validate.

Download the file EZ-Draw-1.2.tgz with your web browser, save the file, then move it into your home directory using the file manager. Next, type in the terminal:

tar xvfz EZ-Draw-1.2.tgz
cd EZ-Draw-1.2
make -j all

After a few moments, modules EZ-Draw, demos and games are compiled. To run demo-01, type in the terminal:

./demo-01

and so on for the other demos and games (for instance ./jeu-bubblet or ./jeu-doddle). Next, read the tutorial.

3.3. Mac OS X

First install XCode from https://developer.apple.com/xcode/download/ using the App Store. This is the development environment of Mac OS X, which includes in particular gcc and make.

Then install Xquartz from http://www.xquartz.org/ , which provides the X11 drawing libraries, necessary for EZ-Draw to work.

Download the file EZ-Draw-1.2.tgz with your web browser, save the file; using the Finder, unpack it as EZ-Draw-1.2.tar, next as folder EZ-Draw-1.2, then move this folder into your home directory.

Note:

if your Finder is not able to unpack, open a terminal and type this:

tar xvfz Downloads/EZ-Draw-1.2.tgz

Next type in a terminal:

cd EZ-Draw-1.2
make -j all

Note:

If you get an error at compile time, for instance

./ez-draw.h:36:10: fatal error: 'X11/Xlib.h' file not found

this means that you must give some paths in the Makefile. You can use the script x11-paths.sh that comes with EZ-Draw; this script explores the system directories and give you some informations. Simply type this in the terminal and wait:

./x11-paths.sh

next, modify the Makefile in section A according to the instructions displayed by the script.

If everything is ok, after a few moments, the modules EZ-Draw, demos and games are compiled. To run demo-01, type in the terminal:

./demo-01

and so on for the other demos and games (for instance ./jeu-bubblet or ./jeu-doddle), or double-click the icons in the Finder. Next, read the tutorial.

Note:

the first run, the program takes some time to launch because the system must first start an X11 server. On some versions of Mac OS X, it might be even necessary to open an xterm before.

3.4. Other Unices

Download the file EZ-Draw-1.2.tgz with your web browser, save the file, then move it into your home directory using the file manager. Next, type in the terminal:

gunzip EZ-Draw-1.2.tgz
tar xvf EZ-Draw-1.2.tar
cd EZ-Draw-1.2
make all

Note:

in case of errors at compile time, make sure you have on your system:

• bash
• gcc and development files .h
• make (GNU version)
• X11 development version: check for Xlib.h (probably in /usr/include/X11), for libX11.so (probably in /usr/X11R6/lib or /usr/lib), and for libXext.so (same place).

To check all of this you can use the script x11-paths.sh that comes with EZ-Draw; this script explores the system directories and give you some informations. Simply type this in the terminal and wait:

./x11-paths.sh

If everything is ok, after a few moments, the modules EZ-Draw, demos and games are compiled. To run demo-01, type in the terminal:

./demo-01

and so on for the other demos and games (for instance ./jeu-bubblet or ./jeu-doddle). Next, read the tutorial.

3.5. Windows

Download the file EZ-Draw-1.2.tgz with your web browser and save the file.

Next, uncompress the file, for example with the free software 7-Zip:

1. get 7-Zip on http://www.7-zip.org then install it;
2. in the file manager, right-click on EZ-Draw-1.2.tgz, menu 7-Zip ‣ Extract here then again on EZ-Draw-1.2.tar.
3. You can then leave this folder on the desktop, or drag it in “My Documents” for example.

Install MinGW (“Minimal GNU for Windows”) to get gcc and GNU make :

1. go to: http://sourceforge.net/projects/tdm-gcc/ ;
2. click on “Download tdm-gcc-xxx.ex”, wait, then click on “Save file”.
3. Double-click on the file, then click on “Run”: the installation window appears.
4. Click on “Create”, then “MinGW/TDM (32-bit)”, “Next”.
5. Leave “Installation Directory” as c:\MinGW32, click on “Next”.
6. Select a mirror, for example “[Europe - France] Free France”, then “Next”.
7. Select the installation “TDM-GCC Recommended, C/C++” then click on “Install”.
8. When the installation is “Completed successfully”, click “Next” then “Finish”.
9. If a terminal was open, close it now.

Open a new terminal:

• On Windows 8, bring up the sidebar to the right of the screen, click on “Search”, then “Command Prompt”;
• On Windows 7 or earlier versions, click on Start ‣ All programs ‣ Accessories ‣ Command Prompt.

Still in your terminal, go into the directory EZ-Draw-1.2 by typing :

cd c:\realpath\EZ-Draw-1.2

replacing c:\realpath\EZ-Draw-1.2 by the actual path. To know, just drag the folder icon EZ-Draw-1.2 in the terminal.

Compile by typing:

make.bat all

Note:

If the compilation fails and you get the error message “The specified path was not found”, you must change the PATH, by typing in the terminal:

set PATH=c:\MinGW32\bin;%PATH%

After a few moments, modules EZ-Draw, demos and games are compiled. To run demo-01, type in the terminal:

demo-01

and so on for the other demos and games (for instance jeu-bubblet or jeu-doddle).

Next, read the tutorial. To edit examples, install GVim for instance, see http://www.vim.org .

Note:

I did not test other compiler. If it is your case, thanks to share the informations with me so I can complete this document.

3.6. Cygwin

You can install EZ-Draw in two ways:

1. By using the native Windows libraries. You just have to follow the instructions in section Windows. The key point is to not use the Cygwin terminal, but the Windows terminal (“Command Prompt” or cmd).

2. By using the Unix libraries of Cygwin. It is a little more complicated and longer; here are the steps to follow.

If Cygwin is not already installed on your computer, this is time to do it. Go on http://cygwin.com/ then download the “setup” program setup-x86.exe (on Windows 32-bit) or setup-x86_64.exe (64-bit). Follow the instructions; you can keep all the default settings. The setup will download all the basic packages and install them (this may take hours depending on your connexion ... but once for all).

We must now install some additional packages for EZ-Draw. Restart the Cygwin setup then, after the usual setup steps, select the following packages for installation:

• Devel ‣ gcc-core
• Devel ‣ make
• Editors ‣ nedit
• Libs ‣ libX11-devel
• X11 ‣ libXext-devel
• X11 ‣ xorg-server
• X11 ‣ xinit
• X11 ‣ xterm
• X11 ‣ font-sony-misc

Open the Cygwin terminal (there is an icon on the desktop) then type

startxwin &

This starts the X11 server (that is to say, the graphic mode of Unix) and open a new terminal “XWin”. All the next commands will have to be typed in this terminal.

Note:

if startxwin displays Another X server instance is running on display :0, type ps, get the number at the beginning of the line where stands /usr/bin/XWin, then type kill <pid> by replacing <pid> by the number; you can finally type again startxwin &

Download the file EZ-Draw-1.2.tgz with your web browser, save the file, then move it into your Cygwin home directory using the file manager. This directory is like to be c:\cygwin32\home\<your-login> or c:\cygwin64\home\<your-login>.

Type ls in the XWin terminal to check if you actually have the file EZ-Draw-1.2.tgz in your Cygwin home directory. Type next:

tar xvfz EZ-Draw-1.2.tgz
cd EZ-Draw-1.2

We can now compile EZ-Draw: type

make -j all

After a few moments, modules EZ-Draw, demos and games are compiled. To run demo-01, type in the terminal:

./demo-01

If you get the message ez_init: XOpenDisplay failed for "", then you used the wrong terminal; remember, you must type the commands in the XWin terminal.

Do the same to run the other demos and games (for instance ./jeu-bubblet or ./jeu-doddle). Next, read the tutorial.
