ヤること - yamanetoshi's diary

無線 dongle
- wpa_supplicant
GPS
- libfreerunner_gps

両方が微妙に関係しているあたりが微妙なんですが。
gcj が邪魔をしているみたいなのでパケジ削除。

で、ようやくコンパイルが正常終了している臭いコトを確認。現時点で以下なカンジ。

$ ~/bin/repo status
# on branch a500fx
project external/webkit/                        branch a500fx

 -m     init/devices.c

 -m     init/logo.c
 --     init/logo.c.orig
$

とりあえずこの状態で commit してさらに branch する形で動作を見てみる方向で。

$ ~/bin/repo status
# on branch a500fx
nothing to commit (working directory clean)
$ ~/bin/repo branches
*  a500fx                    | in all projects
   master                    | in all projects
$

で、a500fx を基に branch すれば良いのか。

$ ~/bin/repo start freerunner --all
Starting freerunner: 100% (152/152), done.  
$

で、mm とか mmm のナニをソレ。とりあえず

$ cd $ANDROID/external
$ git clone git://gitorious.org/android-on-freerunner/freerunner_platform_hardware_hw.git
$ cd freerunner_platform_hardware_hw

ええと、mm が_Builds all of the modules in the current directory._ってコトなので何も考えずにここで mm してみるか。

gps/Android.mk がこうなっているので、gps 配下は完全スルー。

$ cat gps/Android.mk
# hardware/libfreerunner_gps/Android.mk

ifeq ($(strip $(BOARD_HAVE_FREERUNNER_GPS)),true)

$ANDROID/vendor/sola/a500fx/BoardConfig.mk に

BOARD_HAVE_FREERUNNER_GPS := true

を追加して再度 mm してみます。

む、build/tools/apriori/prelinkmap.c って何だ。

と言いつつ

build/core/prelink-linux-arm.map というテキストを発見。中身を見るに、こっちに情報を登録すべきなのか、AndroidでJNIを使う方法にある通り

LOCAL_PRELINK_MODULE := false

を Android.mk に追加するべきなのかが微妙。
下記を確認したら

http://gitorious.com/android-on-freerunner/platform_build/commit/a2c5749b8ff171d0263bb4c20daa58717f7cb7d6

末端に追加されているな。という事は以下で良いのだろうか。

# libraries for specific apps or temporary libraries
--中略--
libcerttool_jni.so      0x9A100000
libfreerunner_gps.so    0x9A000000

これで再度 mm 実行してみたらどうか。

を、system/lib に入ったな。これでコンパイルから導入は大丈夫なので次は中身を触らないといけません。あ、良く考えたら BoardConfig.mk に以下も追加が必要なのかな。

BOARD_GPS_LIBRARIES := libfreerunner_gps

上記追加して mm してみたらどうなるのかな。

なんとなく gps.cpp がリコンパイルされた風では無さげに見えるのは気のせいかなぁ。ライブラリを消してみて再度 mm してみます。

これ、全部が clean されちゃったクサいんですが (とほほ

という事でリコンパイル実施

駄目すぎる。なんとなく全部コンパイルしてそげに見えるんで今日はもう駄目かな。

追記

良く考えたら branch 作り直せば良いんだった。なるべく全コンパイルを避けるために branch 作る事にしたんだからこのあたりは上手に使わんとの。
とりあえず branch の削除の方法は分からんが作り直し。

$ ~/bin/repo branches
   a500fx                    | in all projects
*  freerunner                | in all projects
   master                    | in all projects
$ ~/bin/repo checkout a500fx
Checkout a500fx: 100% (152/152), done.  
$ ~/bin/repo branches
*  a500fx                    | in all projects
   freerunner                | in all projects
   master                    | in all projects
$ ~/bin/repo start freerunner2 --all
Starting freerunner2: 100% (152/152), done.  
$

元に戻せたんですが、どうするか考え中。

BOARD_HAVE_FREERUNNER_GPS := true を BoardConfig.mk に追加
build/core/prelink-linux-arm.map 末端にエントリ追加
BOARD_GPS_LIBRARIES := libfreerunner_gps を BoardConfig.mk に追加

で、今日の敗因は libhardware_legacy で mm しなかったのが悪かったのかなぁ。ターゲットを削除するだけではなくて .o なソレを削除しないと駄目、って事なのか。

あら?

新たに作成させて頂いた branch で mm できん。なんとなく out 配下が微妙だったので make し直してみます。若干 repo って微妙だなぁ。
とりあえず、あるプロジェクトのみリコンパイルって無理なのかどうなのか。
