Masalah Linux pun ya, Android pun ya...

Aku tgh nak recompile kernel Android untuk Xperia X8, guna source code dari Sony Ericsson.

Environment : Ubuntu 10.10 over VirtualBox over Windows 7

Aku buat dua folder :

~/android/source/ : untuk source code dari SonyEricsson
~/myandroid/ : untuk source code dari Git repository dari Google (repo init -u git://android.git.kernel.org/platform/manifest.git), ia tak mengandungi source kernel, cuma cabang Platform sahaja, sebab yang penting adalah fail yang ada dalam folder /platform/toolchain seperti compiler.

working directory sewaktu compile adalah di ~/android/source/kernel/



Setting :

export ARCH=arm
export CROSS_COMPILE=arm-eabi-
export PATH=$PATH:~/myandroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin


.config aku ambil dari Android 1.6 X10
untuk telefon versi selepas dari 1.6 memang tiada fail /proc/config.gz dalam telefon.


pertama kali, aku compile tanpa ubah apa-apa. Semua OK.

kali kedua, aku make clean, aku ubah pada .config :
1. feature untuk swap support pada kernel
2. tukar processor kepada MSM_72X7
3. ubah board kepada "Shakira" (codename untuk X8)

kemudian aku dapat error ni :

Code: 
arch/arm/mach-msm/built-in.o: In function `shakira_gpio_event_matrix_func':
/home/android/android/sources/kernel/arch/arm/mach-msm/board-shakira-keypad.c:90: undefined reference to `semc_gpio_event_matrix_func'

android tu dua kali sebab username linux aku pun android.

aku dah google, tiada satu pun kes ni disebut.

aku dah periksa semua fail (ada 5) yang menyebut kata kunci "semc_gpio_event_matrix_func" semuanya memanggil header file dengan baik... malah aku tukar dari #include <header.file> jadi #include "header.file"

biasanya masalah compile "undefined reference to" dikatakan berkaitan soal linking sama ada dynamic atau static.

bagaimana nak ubah benda tu dalam "makefile" atau "make file" (android_kernel.mk)? bagaimana pula nak link secara statik/dinamik untuk fail ini sahaja...






dalam semua fail di bawah ~/android/sources tu, cuma 5 yang ada sebut "semc_gpio_event_matrix_func"

  1. /home/android/android/sources/kernel/arch/arm/mach-msm/board-mimmi-keypad.c
  2. /home/android/android/sources/kernel/arch/arm/mach-msm/board-robyn-keypad.c
  3. /home/android/android/sources/kernel/arch/arm/mach-msm/board-shakira-keypad.c
  4. /home/android/android/sources/kernel/drivers/misc/semc/gpio_matrix/semc_gpio_matrix.c
  5. /home/android/android/sources/kernel/include/linux/semc/gpio_event.h


Fail berwarna merah tidak digunakan, ia untuk handphone SE model lain.

Berikut adalah fail-fail yang terlibat :

#include <linux/gpio_event.h>
#include <linux/input.h>

int semc_gpio_event_matrix_func(struct gpio_event_input_devs *input_dev, 
struct gpio_event_info *info, void **data, int func);

int semc_gpio_event_input_func(struct gpio_event_input_devs *input_dev,	
struct gpio_event_info *info, void **data, int func);

#endif /*_SEMC_GPIO_EVENT_H_*/

apa yang tak kena, ya?








Bagi yang biasa compile driver dan kernel Linux (dan apa-apa software yang perlu customization), rasanya dah masak dengan benda ni.
Jadi minta bantuan dan pendapat.



terima kasih.

anybody who feels like helping, don't bother downloading the code..

original SE source = 145MB
android platform repo = 2.5GB
android kernel repo = 1.5GB

if you need to see any file, or the file structure, just ask.

but if you insist, here's the url :

android : android.git.kernel.org
SE : http://developer.sonyericsson.com/cws/devworld/search-downloads/opensource?cc=gb&lc=en ( x10_x10mini_X10minipro_x8_eclair_2.1.A.0.435.tar.gz)

Terima kasih...

Rasanya calonnya tidak perlu handal sangat Linux, cukup kalau biasa sangat main dengan makefile dan compile itu ini.

Kebanyakan aplikasi yang sedikit teknikal dalam Linux (contoh : video/audio encoder/decoder), di download source code dan dicompile sendiri. Biasanya perlu diubah setting compilation-nya.

Tak perlu tahu pasal Android pun, rasanya la.





Aku rasa aku selalu tengok orang cerita pasal Linux dalam CG ni dulu.
 
Aku dah jumpa... Sony Ericsson sengaja kasi fail yang tak boleh nak dicompile tanpa diperbetulkan dulu, kaitan antara satu fail dengan fail lain yang berkenaan banyak yang hilang (dalam #include dan kat dalam makefile), banyak fail penting (drivers, yang penting macam simcard dectection tak dicompile jadi object)... Mulut cakap Open Source, tapi tak ikhlas.

FALAT.



Siapa terror makefile kat sini?

aku nak teruskan soalan, tapi nak tanya dulu...

ini dah tak ada kena mengena dengan Android lagi dah... it's all about compiling your codes in Linux environment.

Tolong... Aku bukan nak korang buatkan kerja, just point me to the right direction.
