I am currently editing this very outdated article! English version updated: 23.12.2007 - Newest Gentoo Version are now 2.2.5.

Introduction

Gentoo is known for choices. Unfortunately, some choices require more labor than others. As such, aMule comes in a variety of versions and installation methods based on what version of wxGTK you decide to use...

Methods of Installation

amule-2.2.5.ebuild

This ebuild matches the 2.2.5 stable aMule release, it is available 28.08.2009 in portage.

Dependencies: >=x11-libs/wxGTK-2.8*; >=dev-libs/crypto++-5.5.2; >=sys-libs/zlib-1.2.1

Conditional dependencies: >=dev-libs/geoip for geoip support; >=net-libs/libupnp for Intel UPnP stack support; >=media-libs/libpng-1.2.0 for remote support; >=media-libs/gd-2.0.26 for unicode support and or statistic reporting.

Installation instructions

They must be updated to reflect the actual portage state. Some volunteer?

amule-2.1.3.ebuild

1. Emerge package: 

 emerge --sync
 emerge amule -pv
 emerge amule

amule SVN (latest one)

It is no ebuild for the current aMule SVN so we need to add one in portage. For that, we will make use of a personal portage overlay. If you don't already have one, just follow this HOWTO article: HOWTO Installing 3rd Party Ebuilds

We will also follow the naming scheme of portage. SVN ebuild from a SVN tarball are not named as package_name-SVN but as package_name-version_date_of_the_tarball. That is to distinguish them from real SVN ebuilds (the so called live ebuilds) named as package_name-9999 and using keywords="".

1. Define PORTDIR_OVERLAY. Open up /etc/make.conf with your favourite text editor and define the PORTDIR_OVERLAY variable. We will use: 

 PORTDIR_OVERLAY="/usr/local/portage"

2. Create overlay for amule-svn: 

 mkdir -p /usr/local/net-p2p/amule

3. Add to package.keywords: 

 echo "net-p2p/amule ~x86" >> /etc/portage/package.keywords

4. Copy the following ebuild into {PORTDIR_OVERLAY}/net-p2p/amule/amule-2.2.0_p20071217.ebuild

I use here the tarball from 17 December 2007 that was working fine for me, but you can change the date like you want. I use p in order to distinguish this ebuild from the ones in portage (using pre).

5. Change directory: 

 cd /usr/local/portage/net-p2p/amule/

6. Digest the ebuild: 

 ebuild amule-2.2.0_p10071217.ebuild digest

7. Review installation flags: 

 emerge amule -pv

8. Modify /etc/portage/package.use to suit your needs (please note that debug is enabled regardless of USE flag): 

 net-p2p/amule -amuled -debug geoip gtk nls -remote -stats unicode

This would install amule without deamon and remote support. To activate deamons and remote options, leave out the '-' like this: 

 net-p2p/amule amuled -debug geoip gtk nls remote -stats unicode

As aMule needs unicode support or it won't compile, you might also want to add a line to enable unicode in x11-libs/wxGTK 

 x11-libs/wxGTK unicode

9. Install aMule SVN: 

 emerge amule

PLEASE do emerge amule -pv before installing to determine how you want to compile aMule.

aMule 2.1.1 Compilation FAQ

When compiling aMule-2.1.1 on a hardened system with gcc-3.4.5(at least), it will fail with something like: 

WebServer.h: In member function `T* UpdatableItemsContainer<T, G, I>::GetByID(I) [with T = SharedFile, G = CEC_SharedFile_Tag, I = CMD4Hash]':
WebServer.h:270: internal compiler error: in sweep_string_variable, at protector.c:1158

The possible problem is the -fPIE CFLAG because using `gcc-config` to select i386-pc-linux-gnu-3.4.5-hardenednopiessp fixed the problem, and you can even remove from the ebuild: 

if has_hardened; then
    filter-flags -fstack-protector -fstack-protector-all
fi
