Setup Environment

  • Open the apt sources to add canonical for the sun-java6-jdk package
vim /etc/apt/sources.list
  • Add non-free to the end of the deb line
  • Setup development environment:
aptitude install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev sun-java6-jdk pngcrush g++-multilib gcc-4.3-multilib g++-4.3-multilib schedtool lzma
  • 64-Bit
aptitude install lib32z1-dev lib32ncurses5-dev lib32readline5-dev
  • 32-Bit
aptitude install libreadline5-dev libncurses5-dev
  • Create Directories:
mkdir -p ~/bin
mkdir -p ~/android/system
cd ~/android/system
  • Setup Repository
curl http://android.git.kernel.org/repo > ~/bin/repo
chmod a+x ~/bin/repo
reboot
  • Initialize Repository
repo init -u git://github.com/teamhacksung/android.git -b gingerbread

Syncing Repository

repo sync -j2

NOTE: I see others using -j<large number> and this for some reason causes errors for me, such as: 

Fetching projects:  56% (134/239)  fatal: Unable to look up android.git.kernel.org (port 9418) (Name or service not known)
error: Cannot fetch platform/external/tcpdump

Download ROMManager and gApps

This is typically only needed one time. 

./build.sh prepare

Build Initial

The initial needs to be done only the first time you convert over to CyanogenMod. 

cd ~/android/system/releasetools
./efsbackup.sh captivate
./initial.sh captivate

The efsbackup.sh script will generate: 

~/android/system/out/target/product/captivate/captivate-efsbackup.zip

The initial.sh script will generate: 

~/android/system/out/target/product/captivate/cm7-captivate-initial-20110318.zip
~/android/system/out/target/product/captivate/cm7-captivate-initial-kernel.tar

Build Update

cd ~/android/system
./build.sh captivate

The build.sh script will generate: 

~/android/system/out/target/product/captivate/update-cm-7.0.0-RC0-Captivate-KANG-signed.zip

Initial Update

Check List

Verify HSPA

If you're doing this the first time then you need to make sure that you haven't disabled anything in HSPA.

  • Dial *#301279# on your phone
  • Select:
[2] CHANGE HSPA REVISION
  • Select:
[3] RELEASE 6 (HSDPA/HSUPA)

You'll then see: 

CHANGE_REL5
HSDPA ON, HSUPA ON
  • Press menu then end

Verify Space

  • Ensure you have at least 200MB free on your internal sd card (\sdcard)

Verify Charge

  • Ensure your battery is charged to 100% as the process will a bit of time

Flashing Initial

Preparing

  • Attach your phone to the wall wart
  • Copy the following to your internal sd card (\sdcard)
~/android/system/out/target/product/captivate/captivate-efsbackup.zip
~/android/system/out/target/product/captivate/cm7-captivate-initial-20110318.zip
  • If your already on a ROM with ClockworkMod Recovery, then you can skip this next section to move on to "Installing CyanogenMod"

Flashing Kernel with ClockworkMod Recovery

  • If your on stock, then you need to download a kernel with ClockworkMod Recovery and flash it instead of a full blown ROM
wget http://crackerjackbox.com/android/speedmod-kernel-i897-k13c-500hz.tar
  • Extract the zImage from the archive
tar xf speedmod-kernel-i897-k13c-500hz.tar
  • Put phone in download mode (The yellow screen that says "Downloading..." "Do not turn off Target!!")
  • Connect the phone up to the computer via USB
  • On the computer run:
heimdall flash --kernel ./zImage
  • Once done it will reboot but it can't load all the way, so just pull the battery then continue on below

Installing CyanogenMod

  • Reboot into recovery mode using 3 button combo, see Method 1 here for how

NOTE: CyanogenMod wiki says: Don't use "reboot recovery" command or other shiny things to do this! I don't know why, but I'm not one to throw caution into the wind.

  • In the "ClockworkMod Recovery" menu:
    • Select "install zip from sdcard"
    • Select "choose zip from sdcard"
    • Scroll down and select "captivate-efsbackup.zip"
    • Scroll down and select "Yes - Install captivate-efsbackup.zip"

Your output should be as such: 

-- Installing: SDCARD:captivate-efsbackup.zip

Install from sdcard complete
  • Still in the ClockworkMod menu:
    • Select "+++++Go Back+++++"
    • Select "advanced"
    • Select "Reboot to Download mode"
  • You will now be in the yellow "Downloading..." "Do not turn off Target!!" screen (download mode):
  • Connect the phone up to the computer via USB
  • On the computer:
cd ~/android/system/out/target/product/captivate
tar xf cm7-captivate-initial-kernel.tar
heimdall flash --kernel ./zImage

Your output should be as such:

Quick Build

Instead of rebuilding the update all the time and reflashing in CWM, here's a fast way to make a quick change and test.

Manual Initial Build

This is want build.sh does under the hood: 

cd ~/android/system
source build/envsetup.sh
lunch cyanogen_captivate-eng
brunch captivate

Additional Build

Now you can start from here and keep making changes. This example is showing the "SystemUI.apk" 

mmm frameworks/base/packages/SystemUI

Transfer to Phone

./adb shell mount -o remount -rw -n /system
./adb push ~/android/system/out/target/product/captivate/system/app/SystemUI.apk /system/app
./adb shell mount -o remount -r -n /system

Quick Restart

Since SystemUI.apk is the UI we would normally need to reboot to see our changes. Instead we'll just force the UI to reload with the following. 

./adb shell killall system_server

Using Eclipse

After building (from above) without any errors, then follow these steps.

  • Copy the .classpath to the root of the repo
cp ~/android/system/development/ide/eclipse/.classpath ~/android/system
  • Run Eclipse
    • Click File->New->Java Project
    • Set "Project name" to Cyanogen
    • Uncheck "Use default location"
    • Change "Location" to ~/android/system/
    • Click Next
    • It will take a few moments, so be patient
    • Click Finish

Restore to Factory

Eclair

error: can't find a register in class 'GENERAL_REGS' while reloading 'asm'

If you get this error, detail provided below, then it's because your gcc is out of date and has a bug! I know that gcc that comes with lenny (4.3) has this bug. Once I rebuilt my lxc with squeeze, which has "gcc (Debian 4.4.5-8) 4.4.5", I had no problems whatsoever with this error.
