Replicant

h1. Replicant 6.0 build dependencies installation

*Replicant can only be built on 64 bit x86 architectures, building on 32 bit x86 systems is no longer supported.*

However, some prebuilt tools are still 32 bit x86 executables and some host tools are generated as 32 bit x86 executables.

It is recommended to have at least 4GB of RAM available.

h2. Debian-based systems

*Debian 9*

Packages installation:

<pre>

dpkg --add-architecture i386 ; apt-get update

apt-get build-dep gcc binutils llvm-defaults

apt-get install bash gcc-arm-none-eabi cmake python-dev swig ant bc proguard maven-debian-helper libemma-java libasm4-java libguava-java libnb-platform18-java libnb-org-openide-util-java libandroidsdk-ddmlib-java libmaven-source-plugin-java libfreemarker-java libmaven-javadoc-plugin-java ca-cacert curl gawk libgmp3-dev libmpfr-dev libmpc-dev git-core gperf libncurses-dev squashfs-tools pngcrush zip zlib1g-dev lzma libc6-dev-i386 g++-multilib lib32z1-dev lib32readline-dev lib32ncurses5-dev zlib1g-dev:i386 xsltproc python-mako schedtool gradle dirmngr libandroidsdk-sdklib-java eclipse-jdt libgradle-android-plugin-java android-sdk-build-tools android-sdk-platform-23 aapt lzop rsync

As @repo@ tend to update itself (by downloading a new version of repo and running it) and that newer versions of repos also require newer versions of python, it doesn't work anymore on Debian 9 (stretch). 

To work around that, we also released "a version of repo that is self-contained":https://ftp.osuosl.org/pub/replicant/build-tools/repo/ . Make sure to read the README for installation instructions. The README content is also signed with gpg (by [[People#Denis-GNUtoo-Carikli|Denis 'GNUtoo' Carikli]], who at the time of writing did the last Replicant 6 Release Candidates).

In addition you also need to workaround some issues with Debian 9 (stretch) with the path of grep, sed, and mkdir that prevent building the toolchain. See the [[Replicant60BuildTips#usrbingrep-usrbinsed-usrbinmkdir-No-such-file-or-directory|/usr/bin/grep, /usr/bin/sed, /usr/bin/mkdir: No such file or directory¶]] section for how to do that.
