The following steps will lead you to install [[aMule]] in your [http://www.apple.com/macosx MacOS X] box.

You can get also the most recent binnary of [[aMule]] for [http://www.apple.com/macosx MacOS X] dowloading this: http://download.berlios.de/amule/aMule.zip

This HowTo is written to compile and install [[aMule]] 2.0.0-rc8. It will not work for older versions. Please note that you should always download the latest [[aMule]] version available.

'''NOTE:''' This document explains how to download files using [http://curl.haxx.se curl]. However, [http://curl.haxx.se curl] might not be installed on your system: either install it (you can use [http://fink.sourceforge.net Fink] to install it) or download the files with whatever application you want (maybe your web browser), but place them in the directory that's being used on each part of the guide, otherwise the commands that are shown here will not work.

== Setting up the required environment ==

These steps are one-time-only steps necessary for the steps in the following sections to work properly.

# Xcode
## Install [http://developer.apple.com/tools/xcode Xcode Tools] from http://developer.apple.com/tools/download
## "Getting ADC ID"->"Log In"->"Download Software"->"Developer Tools"->"Download Xcode Tools last release">"Install"
# Fink
## Install (or verify installation if already installed) [http://fink.sourceforge.net Fink] from http://fink.sourceforge.net/download
# gettext
## Using [http://fink.sourceforge.net Fink], install [http://www.gnu.org/software/gettext gettext]. Read [http://fink.sourceforge.net/download Fink's installation guide] to learn how to install applications through [http://fink.sourceforge.net Fink] (the [http://www.gnu.org/software/gettext gettext] package is ''gettext'').
# Working directories
## Make ''amule'' dir in your home directory: ''mkdir ~/amule''
## Make ''wxmac'' dir in your home directory: ''mkdir ~/wxmac''

== Obtaining [[wxMac]] sources ==

'''ATTENTION:''' [[wxMac]] 2.5.3 has a couple of bugs which cause [[aMule]] 2.0.0-rc8 to crash. One bug causes [[aMule]] to crash just after starting up, the other causes it to crash at a random later time :-(. The only work-around is to pull the wxWidgets sources from CVS!

You have two options, downloading a CVS snapshot or performing a checkout through the wxWidgets CVS server. The snapshot may be faster to download; the CVS server will give you the most up-to-date sources and the most flexibility if you need sources from a previous day (for example, to avoid bugs that may crop up in the ever-changing source). On the other hand, the sources from the snapshot, once extracted, take nearly 6 times as much disk space as those checked out from the CVS server because they include files not necessary for compiling on Mac OS X.

'''NOTE:''' As of 2005-01-18, the wxMac developers have approved the patch for the last of these crashing bugs. Therefore, it is no longer necessary for you to apply any patches yourself. A checkout from the CVS server will include the fix. The CVS snapshot won't include the fix until 2005-01-19, so until then use the CVS server checkout method.

=== '''Option 1:''' Obtaining [[wxMac]] sources from CVS snapshot ===

These instructions were adapted from http://wxwidgets.org/cvs.htm

# Enter the ''wxmac'' directory: ''cd ~/wxmac''
# Get the [[wxMac]] CVS snapshot (found at [http://wxwindows.sourceforge.net/snapshots/ http://wxwindows.sourceforge.net/snapshots/] as ''wx-cvs.tar.bz2'') and place it in your ''~/wxmac'' directory: ''curl -O http://biolpc22.york.ac.uk/pub/CVS_HEAD/wx-cvs.tar.bz2''
# Extract it: ''tar -xjf wx-cvs.tar.bz2''
# '''Optional:''' You may delete the archive after extracting its contents: ''rm wx-cvs.tar.bz2''

=== '''Option 2:''' Obtaining [[wxMac]] sources from CVS server ===

These instructions were adapted from http://wxwidgets.org/cvs.htm

# Enter the ''wxmac'' directory: ''cd ~/wxmac''
# Login (anonymously) to the wxWidgets CVS server (when prompted, enter ''anoncvs'' as the password): ''cvs -d :pserver:anoncvs@cvs.wxwidgets.org:/pack/cvsroots/wxwidgets login''
# Checkout the [[wxMac]] sources from CVS: ''cvs -d :pserver:anoncvs@cvs.wxwidgets.org:/pack/cvsroots/wxwidgets checkout wxMac''

== '''Optional:''' Patching the [[wxMac]] sources ==

'''NOTE:''' As explained above, it is no longer necessary to patch the [[wxMac]] sources to avoid crashing bugs. This section remains for those adventurous souls willing to apply the as-yet-unapproved patches for some memory leaks.

The [[wxMac]] sources still contain some bugs which cause aMule to leak memory. Patches to fix [[wxMac]] have been submitted to the wxWidgets team. These patches have not yet been approved by the wxWidgets developers and so should be considered experimental and approached with caution.

# Enter the ''wxmac'' directory: ''cd ~/wxmac''
# Patch some memory leaks in [[wxMac]].
## Download the patch files: ''curl "http://sourceforge.net/tracker/download.php?group_id=9863&atid=309863&file_id=112952&aid=1088052" -o ctable.patch "http://sourceforge.net/tracker/download.php?group_id=9863&atid=309863&file_id=112949&aid=1088038" -o bitmap.patch''
## Apply the patches: ''cat ctable.patch bitmap.patch | patch -p0 -d wxWidgets''

== Installing [[wxMac]] from sources ==

# Enter the directory containing the [[wxMac]] sources: ''cd ~/wxmac/wxWidgets''
# Directory ''build'' should already be there. If not, create it with: ''mkdir build''
# Now enter ''build'' directory: ''cd build''
# Prepare the compilation: ''../configure''
# And compile: ''make''
# Now install [[wxMac]] compilation: ''sudo make install''
# Get back to your home directory, you're done: ''cd ~''
# '''Optional:''' If everything went ok, you can safely remove the [[wxMac]] sources (not recommended, since you might want to compile it again someday): ''rm -r ~/wxmac

== Compiling and installing [[aMule]] ==

# Enter the ''amule'' directory: ''cd ~/amule''
# Get [[aMule]]'s latest source code (aMule 2.0.0-rc8 sourcecode: [http://download.berlios.de/amule/aMule-2.0.0rc8.tar.bz2 http://download.berlios.de/amule/aMule-2.0.0rc8.tar.bz2]) and place it in your ''~/amule'' directory: ''curl -O http://download.berlios.de/amule/aMule-2.0.0rc8.tar.bz2''
# Extract it: ''tar -xjf aMule-2.0.0rc8.tar.bz2''
# Enter [[aMule]]'s sources directory: ''cd aMule-2.0.0rc8''
# Prepare the compilation (thanks to '''one_2_one''' and '''Babboia''' for his test&fix): ''./configure --disable-systray --disable-gtk --with-wx-config=/usr/local/bin/wx-config''
# And compile it: ''make''
# '''Optional:''' You can reduce the size of [[aMule]] from 44MB to 3MB by doing the following (anyway, this will make the [[aMule]] binary lose debug info, so you'll be unable to report problems to the [[aMule devs|aMule Team]] to make [[aMule]] a better program; so, it is not recommended): ''strip src/amule''
# Copy the ''amule'' binary to the app-Container directory: ''cp src/amule amule.app/Contents/MacOS/'' ('''NOTE:''' If the ''MacOS'' directory is missing in ''amule.app'', create it by typing ''mkdir amule.app/Contents/MacOS'' before executing the previous command. Thanks to '''dan''' for the tip)
# And copy ''amule.app'' directory to your Applications folder: ''cp -R amule.app /Applications''
# Get back to your home directory, you're done: ''cd ~''
# If everything went OK, you can safely remove the downloaded packages:
## Remove [[aMule]]'s sources package: ''rm ~/amule/aMule-2.0.0rc8.tar.bz2''
## Optionally remove the extracted [[aMule]] sources (not recommended, since you might want to compile it again someday): ''rm -r ~/amule''

== Problems and solutions ==

*If [http://fink.sourceforge.net Fink] reports something like: ''After unpacking 11.2GB will be freed'', don't be afraid. [http://fink.sourceforge.net Fink] has evolved into a different way of managing packet's size and some old ("old": at least some months old) packages' sizes aren't handled correctly on the output. If this is your case, devide the number by 1024. So, what the above example really means is: ''After unpacking 11.2MB will be freed''.

*If you get an error like this: ''You cannot open the application "amule" because it may be damaged or incomplete'', right click on ''amule'', then click on ''Show Packages Contents'', go to "Contents">"MacOS"> and double click on ''amule''. Next time you start from ''amule.app'' it will run fine. If you still get the same error, move ''amule.app'' to the desktop and run it from there.

== Older releases ==

In older releases ([[aMule]] 2.0.0-rc7 and earlier), the app container wasn't included with the sources. If you are compiling any of this older releases and do not whish to upgrade (remember it is '''strongly''' recommended to upgrade to the latest release), you can:

*Download the latest [[aMule]] sources and get the app container from there (recommended option).
*Download [http://download.berlios.de/amule/aMule-App-Container.tar.bz2 aMule's app-Container]: ''curl -O http://download.berlios.de/amule/aMule-App-Container.tar.bz2''

You must extract the app container in your ''amule'' directory: possible ''~/amule''
To extract it: ''tar -xjf aMule-App-Container.tar.bz2''

'''NOTE:''' If the app-Container failed to extract try running this command instead of the app-Container extraction step: ''mkdir -p amule.app/Contents/MacOS''

Once the installation is finished, you can safely remove the app-Container package: ''rm aMule-App-Container.tar.bz2''
