Debian / Ubuntu

Prerequisities

The Haxe compiler is written in the OCaml language. Therefore we have to install Ocaml first. Additionally we make sure to have the most important tools and libraries installed.

sudo apt-get install ocaml camlp4 ocaml-findlib cvs zlib1g-dev make wget tar subversion

Make sure to uninstall previous versions of Haxe installed via .deb packages or manually.

sudo apt-get remove haxe

and

sudo rm -rf /usr/lib/haxe
sudo rm -rf /usr/bin/haxe*

Installation

You can use the following shell script for the complete build and install process.

1. copy the contents of the installation script into a shell script, like "installhaxe.sh"

vim installhaxe.sh

2. make it executable:

sudo chmod 0755 installhaxe.sh

3. run it:

./installhaxe.sh

installation script:

#!/bin/sh
# installhaxe.sh
#
# Build the haxe compiler
# =====================
# - download 'install.ml' and execute it (compiles the haxe compiler)
# - copy the executables and modifies the evironment variables

# My libz was in a different place, maybe uncommenting helps
# sudo ln -s /usr/lib/i386-linux-gnu/libz.so /usr/lib/libz.so

mkdir haxesrc
cd haxesrc

wget http://code.google.com/p/haxe/source/browse/trunk/doc/install.ml
ocaml install.ml

# reset previous installations
sudo rm -rf /usr/local/haxe
sudo rm -rf /usr/local/bin/haxe*


# install haxe in /usr/local
sudo mkdir /usr/local/haxe
sudo mkdir /usr/local/haxe/bin
sudo cp bin/* /usr/local/haxe/bin
sudo cp -r haxe/std /usr/local/haxe
sudo ln -s /usr/local/haxe/bin/haxe /usr/local/bin/haxe

# setup environment variables for haxe
sudo grep "HAXE_LIBRARY_PATH" /etc/environment || echo "export HAXE_LIBRARY_PATH=/usr/local/haxe/std:." >> /etc/environment

Environment variables

The following two variables should be defined in your ~/.bashrc file:

1.) $HAXE_LIBRARY_PATH

Please make sure that the haxe compiler finds its libraries by correctly setting up the environment variable in your ~/.bashrc.

2.) $HAXE_HOME

Additionaly it doesn't hurt to define the location of your Haxe installation.

# somewhere in your ~/.bashrc
# ...
export HAXE_LIBRARY_PATH=/usr/local/haxe/std:. # the ':.' part is important
export HAXE_HOME=/usr/local/haxe
PATH=$PATH:$HAXE_LIBRARY_PATH:$HAXE_HOME/bin

To initialize the variables you have to call your ~/.basrc file:

source ~/.bashrc

Final function test

Please run this little test to see if Haxe is able to compile your code.

File Test.hx

 
class Test { 
    static function main() { 
        trace("Hello World !"); 
    } 
}

File compile.hxml:

  
-js test.js
-main Test

Compile it:

 haxe compile.hxml

And here the html code for calling the Javascript:

  
<html>
<head><title>Haxe JS</title></head>
<body>
<div id="haxe:trace"></div>
<script type="text/javascript" src="test.js"></script>

</body>
</html>

Troubleshooting

From the step:

Compile it:

 haxe compile.hxml

In case you get the following error:
Class not found : Test

make sure that your environment variables are correct:

echo $HAXE_LIBRARY_PATH

You should get something like
/usr/local/haxe/std:.

then check if the files are there

$ ls /usr/local/haxe/std/
 Enum.hx  flash9   IntHash.hx  Lambda.hx ...
