This is for the HTC Incredible, see post below for the Droid1 First off, i want to say that this is information taken from various sources, the most predominant being start [CVPCS Android Wiki] and Get Android Source Code | Android Open Source . The only thing i contributed to this guide was that i condensed it a bit and customized it specifically for the incredible, although the only thing that differs from the incredible to other devices it the vendor setup. WARNING: This is NOT FOR NOOBS. If you havent had much experience with working with the Android System, you should not even think about using this guide. This is a guide for building AOSP on Ubuntu Lucid Lynx (10.04). If you have Mac, i cant help you much. If you have Windows, i strongly reccommend that if you havent already done so, download Ubuntu onto a CDROM and run wubi.exe to trial ubuntu. THERE WILL NEVER BE A GUIDE FOR BUILDING ON WINDOWS!!!!!!!!! Ok, so now that all that stuff is over, heres your guide: First, we want to install java5. Java6, the newest java is NOT supported due to @Override incompatibilities Code: sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev You might also want Valgrind, a tool that will help you find memory leaks, stack corruption, array bounds overflows, etc. Code: sudo apt-get install valgrind Set the system to use the right version of java by default: Code: sudo update-java-alternatives -s java-1.5.0-sun Now to install the repo Code: cd ~/ mkdir bin echo $PATH Download thereposcript and make sure it is executable: Code: curl http://android.git.kernel.org/repo >~/bin/repo chmod a+x ~/bin/repo Create an empty directory to hold your working files: Code: mkdir mydroid cd mydroid Run "repo init" to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest: Code: repo init -u git://android.git.kernel.org/platform/manifest.git -b gingerbread When prompted, configure Repo with your real name and email address. If you plan to submit code, use an email address that is associated with a Google account . A successful initialization will end with a message such as repo initialized in /mydroid Now to download all the files you need. To pull down files to your working directory from the repositories as specified in the default manifest, run Code: repo sync NOTE: The repo sync does tend to take a little long, after all it is 2.1 gigs of files Now to verify the git tags. Doing this wont affect the build, but it doesnt hurt. In your command prompt, type: Code: gpg --import and paste this LONG key into the empty space: Code: -----BEGIN PGP PUBLIC KEY BLOCK----- Version: GnuPG v22.214.171.124 (GNU/Linux) mQGiBEnnWD4RBACt9/h4v9xnnGDou13y3dvOx6/t43LPPIxeJ8eX9WB+8LLuROSV lFhpHawsVAcFlmi7f7jdSRF+OvtZL9ShPKdLfwBJMNkU66/TZmPewS4m782ndtw7 8tR1cXb197Ob8kOfQB3A9yk2XZ4ei4ZC3i6wVdqHLRxABdncwu5hOF9KXwCgkxMD u4PVgChaAJzTYJ1EG+UYBIUEAJmfearb0qRAN7dEoff0FeXsEaUA6U90sEoVks0Z wNj96SA8BL+a1OoEUUfpMhiHyLuQSftxisJxTh+2QclzDviDyaTrkANjdYY7p2cq /HMdOY7LJlHaqtXmZxXjjtw5Uc2QG8UY8aziU3IE9nTjSwCXeJnuyvoizl9/I1S5 jU5SA/9WwIps4SC84ielIXiGWEqq6i6/sk4I9q1YemZF2XVVKnmI1F4iCMtNKsR4 MGSa1gA8s4iQbsKNWPgp7M3a51JCVCu6l/8zTpA+uUGapw4tWCp4o0dpIvDPBEa9 b/aF/ygcR8mh5hgUfpF9IpXdknOsbKCvM9lSSfRciETykZc4wrRCVGhlIEFuZHJv aWQgT3BlbiBTb3VyY2UgUHJvamVjdCA8aW5pdGlhbC1jb250cmlidXRpb25AYW5k cm9pZC5jb20+iGAEExECACAFAknnWD4CGwMGCwkIBwMCBBUCCAMEFgIDAQIeAQIX gAAKCRDorT+BmrEOeNr+AJ42Xy6tEW7r3KzrJxnRX8mij9z8tgCdFfQYiHpYngkI 2t09Ed+9Bm4gmEO5Ag0ESedYRBAIAKVW1JcMBWvV/0Bo9WiByJ9WJ5swMN36/vAl QN4mWRhfzDOk/Rosdb0csAO/l8Kz0gKQPOfObtyYjvI8JMC3rmi+LIvSUT9806Up hisyEmmHv6U8gUb/xHLIanXGxwhYzjgeuAXVCsv+EvoPIHbY4L/KvP5x+oCJIDbk C2b1TvVk9PryzmE4BPIQL/NtgR1oLWm/uWR9zRUFtBnE411aMAN3qnAHBBMZzKMX LWBGWE0znfRrnczI5p49i2YZJAjyX1P2WzmScK49CV82dzLo71MnrF6fj+Udtb5+ OgTg7Cow+8PRaTkJEW5Y2JIZpnRUq0CYxAmHYX79EMKHDSThf/8AAwUIAJPWsB/M pK+KMs/s3r6nJrnYLTfdZhtmQXimpoDMJg1zxmL8UfNUKiQZ6esoAWtDgpqt7Y7s KZ8laHRARonte394hidZzM5nb6hQvpPjt2OlPRsyqVxw4c/KsjADtAuKW9/d8phb N8bTyOJo856qg4oOEzKG9eeF7oaZTYBy33BTL0408sEBxiMior6b8LrZrAhkqDjA vUXRwm/fFKgpsOysxC6xi553CxBUCH2omNV6Ka1LNMwzSp9ILz8jEGqmUtkBszwo G1S8fXgE0Lq3cdDM/GJ4QXP/p6LiwNF99faDMTV3+2SAOGvytOX6KjKVzKOSsfJQ hN0DlsIw8hqJc0WISQQYEQIACQUCSedYRAIbDAAKCRDorT+BmrEOeCUOAJ9qmR0l EXzeoxcdoafxqf6gZlJZlACgkWF7wi2YLW3Oa+jv2QSTlrx4KLM= =Wi5D -----END PGP PUBLIC KEY BLOCK----- And press ctrl d to exit the gpg mode and verify the git tags. Now to setup the vendor overlay: Code: cd ~/mydroid/system/device cd htc mkdir inc cd inc git clone http://github.com/Cyanogenmod/android_device_htc_inc/tree/gingerbread.git inc Code: cd ~/android/system/device/htc/inc ./extract-files.sh NOTE: ADB Must be in your path. You also have to edit the extractfiles.sh so that it reads ./adb pull and not adb pull (add nix boxes) Now to build the build: Code: cd ~/mydroid/system . build/envsetup.sh lunch generic_inc-userdebug make -j`grep 'processor' /proc/cpuinfo | wc -l` otapackage Troubleshooting: Ok, lets say you get an error. most likely its librpc. What you have to do is Code: make clean make librpc Also, you may have to edit some files, add in some proprietaries, so whatch those errors carefully! (also, you may get an error about recovrty not being made...all you have to do is replace the word "mahimahi" in the file to "inc") If the build fails because of java, enter this: Code: export ANDROID_JAVA_HOME=$JAVA_HOME export $PATH Adding SU: This is a bit of a workaround for now, but this is how i did it: 1) Drag and drop superuser.apk from an existing rom and prop it into system/app of your AOSP rom 2) DRag and drop the su binary from an existing rom and drop it into your AOSP rom (in system/bin) Disabling Recovery: go to the root of the rom (in the part where it says "system, Boot.img, META-Inf, recovery-prerec") and delete meta-inf, recovery-prerec. Add in the Meta-INF from HERE (http://bit.ly/gBO1N1), and viola, an AOSP rom with root is born!
