HowTo Compile In Gentoo

English | Deutsch | Español

I am currently editing this very outdated article!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

amule-2.2.5.ebuild

1. Show what will be done:

 emerge -pv amule

2. Adjust your USE flags for amule into /etc/portage/package.use

3. Emerge amule:

 emerge -a amule

amule SVN

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: Overlay: Creating_a_local_overlay

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="". As aMule is using the revision to name the tarball, we will use it for the version_date_of_the_tarball.

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-9732.ebuild

I use here the tarball from 31 July 2009 revision 9732 that was working fine for me, but you can change the revision like you want.

5. Change directory:

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

6. Copy the files directory from PORTAGE:

 cp -r /usr/portage/net-p2p/amule/files files

7. Remove the unneeded files:

 rm files/*.patch

8. Digest the ebuild:

 ebuild amule-9732.ebuild digest

9. Review installation flags:

 emerge amule -pv

10. 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.
