How to build Module for Platform
- It is only for modules are needed to using Android build system.
- Please check its own install information under its folder for other module.
[Step to build]
1. Get android open source.
: version info - Android 4.4
( Download site : http://source.android.com )
2. Copy module that you want to build - to original android open source
If same module exist in android open source, you should replace it. (no overwrite)
# It is possible to build all modules at once.
3. You should add module name to 'PRODUCT_PACKAGES' in 'build\target\product\core.mk' as following case.
case 1) e2fsprog : should add 'e2fsck' to PRODUCT_PACKAGES
case 2) blkid : should add 'libkeyutils' to PRODUCT_PACKAGES
case 3) libhyphenation : should add 'libkeyutils' to PRODUCT_PACKAGES
case 4) KeyUtils : should add 'libkeyutils' to PRODUCT_PACKAGES
case 5) libexifa : should add 'libexifa' to PRODUCT_PACKAGES
case 6) libjpega : should add 'libjpega' to PRODUCT_PACKAGES
ex.) [build\target\product\core.mk] - add all module name for case 1 ~ 5 at once
PRODUCT_PACKAGES += \
e2fsck \
blkid \
libhyphenation \
libkeyutils \
libexifa \
libjpega \
ebtables
4. excute build command
./build_platform.sh
Note :
to build SBrowser (vendor/samsung/packages/apps/SBrowser),
please refer to Buildme.txt at the folder mentioned above.

然后把core.mk里第二部分全都删掉，报的错还是上面那个。
恢复下core.mk重来，
报1：报错external/webkit/Source/WebCore/make-hash-tools.pl line 23.，core.mk砍掉 libwebcore \ 代码砍掉external/webkit.
报2：/home/senrsl/android/source/WORKING_DIRECTORY/external/e2fsprogs/lib/ext2fs/mmp.c:213: undefined reference to `ext2fs_alloc_block2'，external/e2fsprogs 代码换回原版。
