Edit:
We have now a temporary git repository at gitorious:
http://gitorious.org/replicant
== Before starting ==
* Root your phone
* Backup your current system!!!
* Install git
== Setting up the build environment and getting source code ==
These instructions assume that you are building replicant in your home directory (~). If you are building it in another directory, modify path names accordingly.
=== Get the repo tool ===
repo is a front-end to git which is used to manage several git repositories.
{{{
mkdir bin
cd bin
wget http://android.git.kernel.org/repo
chmod a+x repo
cd ..
}}}
=== Check out the Replicant repository ===
This step will download the Android source (minus the kernel) and the Replicant patches.
{{{
mkdir replicant
cd replicant
../bin/repo init -u git://gitorious.org/replicant/manifest.git -b replicant
../bin/repo sync
}}}
== Optional: building the kernel and wireless LAN driver ==
By default, the Android build system uses a pre-compiled kernel and wireless driver rather than compiling these components from scratch. If you want to compile your own copy of either of these components, you have to compile both: the wireless driver sources included with Android are incompatible with the pre-compiled kernel.
=== Get the kernel source ===
To download the kernel sources, create a file in your replicant/.repo directory called "local_manifest.xml" containing the following:
{{{
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="kernel" name="kernel/msm" revision="refs/heads/android-msm-2.6.27"/>
</manifest>
}}}
Then from the ~/replicant/ directory, run:
{{{
../bin/repo sync
}}}
This will create a directory called replicant/kernel and download the kernel sources to it.
=== Build the kernel ===
To build the kernel:
{{{
cd ~/replicant/kernel
export ARCH=arm
export CROSS_COMPILE=arm-eabi-
export PATH=$PATH:~/replicant/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin
cp arch/arm/configs/msm_defconfig .config
make oldconfig && make
}}}
Wait several hours.
=== Point the build system to your kernel ===
Create a file called `~/replicant/buildspec.mk` containing the following:
{{{
TARGET_PRODUCT:=htc_dream
TARGET_PREBUILT_KERNEL:=kernel/arch/arm/boot/zImage
}}}
This will instruct the build process to use your kernel rather than the pre-compiled kernel.
=== Build the wifi module ===
To build the wifi module:
{{{
cd ~/replicant/system/wlan/ti/sta_dk_4_0_4_32
export KERNEL_DIR=~/replicant/kernel/
make
}}}
(If make can't find your compiler, re-run same PATH export command you ran before compiling the kernel.)
Replace the pre-built wifi module with the one you just built:
{{{
cp wlan.ko ~/replicant/vendor/htc/dream-open
}}}
== Build the firmware ==
=== Change the build scripts to include some important missing packages ===
''(This section will be removed once these changes are committed to the replicant repository)''
Open the file {{{~/replicant/vendor/htc/dream-open/htc_dream.mk}}} and at the following text to the beginning of the file:
{{{
PRODUCT_PACKAGES := \
Calculator \
Email \
ImProvider \
SdkSetup \
VoiceDialer
}}}
This will include packages in the build which would otherwise be missing (including the SdkSetup package, which will enable incoming calls).
{{{
cd ~/replicant
make
}}}
Wait and wait and wait.
== Flashing the new firmware ==
[to be written]
== Building individual pieces ==
=== Each time you want to build something ===
* open a new console
* Then type:
{{{
cd ~/replicant
source build/envsetup.sh
export ANDROID_JAVA_HOME=$JAVA_HOME
lunch htc_dream-eng
make
}}}
* The files to flash are in ~/replicant/out/target/product/dream,flash them and then clear the cache
* boot and push the wifi firmware if you want it
=== If you want to build a particular project ===
* open a new console
* build everything if it was not done before
* Then type:
{{{
cd ~/replicant
source build/envsetup.sh
export ANDROID_JAVA_HOME=$JAVA_HOME
lunch htc_dream-eng
#go into the directory containing an Android.mk
mm
}}}
== error workarrounds ==
=== hyts_Foo.c ===
if you have:
{{{
