h1. HTC Magic Build

This explains how to build Replicant for the HTC Magic. 

h2. Prerequisites

Before building, you must make sure:
* You have installed the [[BuildDependencies]]
* You have downloaded Replicant 2.2 sources: [[GettingReplicantSources]]
* Your sources are up to date: [[GettingReplicantSources#DownloadingUpdating-the-source-from-the-repos|Downloading/Updating the source from the repos]]
* You are in the directory where the sources were downloaded
* Know if your HTC Magic is 32B or 32A: see "CyanogenMod wiki":http://wiki.cyanogenmod.com/wiki/How_to_determine_if_you_have_32A_or_32B

h2. Warning

*Do not build as root, always build as user.*

h2. Building

h3. 32B devices

Setup the build environment: 
<pre>
source build/envsetup.sh
lunch replicant_dream_sapphire-eng
export ANDROID_JAVA_HOME=$JAVA_HOME
</pre>

Start the build:
<pre>
parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
make -j$parallel_tasks distimages
</pre>

The -jn argument is to indicate the number of parallel tasks during the build. 
You can remove it from the command line to have only one task at a time. With fast hardware, best results will come with @-j9@, @-j16@ and @-j32@.

h3. 32A/EBI1 devices

Setup the build environment: 
<pre>
source build/envsetup.sh
lunch replicant_dream_sapphire_ebi1-eng
export ANDROID_JAVA_HOME=$JAVA_HOME
</pre>

Start the build:
<pre>
parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
make -j$parallel_tasks distimages
</pre>

The -jn argument is to indicate the number of parallel tasks during the build. 
You can remove it from the command line to have only one task at a time. With fast hardware, best results will come with @-j9@, @-j16@ and @-j32@.

h2. Output files

Find the produced files:
* built target images: @out/target/product/dream_sapphire/@
* built host tools: @out/host/linux-x86/bin/@

For 32A/EBI1 devices, the images to use have the @-ebi1@ prefix.
