Hello glib/gtk guys!
Recently I've been trying on a Android porting work for a project which has which uses glibs-2.22+ including libglib/libgio/libgthread/libgmodule. Other than using the
already-on android/bluetooth/glib with only libglib-2.20 built, I have managed to hack by my own for a full glib porting.
I hope such work will be enrolled into master-glib.
N.B, this hacking is based on glib-2.28.1 and is still raw and unstable,be care of use!
Any correcting and improving is appreciated!
This README.android has all the instructions and patches of my hacking:
======README.android=============
Shohyang Lim <shohyanglim@gmail.com>
Note that this document is not really maintained in a serious fashion. Lots of information here might be misleading or outdated. You
have been warned.
This FULL Android porting is hacked by Shohyang Lim in the porting of one project which uses glibs-2.28 including libglib/libgio/libgthread/libgmodule other than the already-on android/bluetooth/glib with only libglib-2.20 built.
N.B, this hacking is based on glib-2.28.1 and is still raw and unstable,be care of use!
Any correcting and improving is appreciated!
General
=======
In a POSIXer's view, Android system is CRIPPLED: thus the porting of existing libraries onto it is TOUGH. Please have this in mind.
The basic obstacles in porting:
1.Android does not have or offers less/no access in its rimmed bionic C lib :
1>No SYS V shm.h/sem.h
2>Not standard pwd.h and getpwuid_r(),etc. methods
3>No locale.h
4>Not standard IP/IPV6 headers/support such as arpa/*.h ones
5>Not standard pthread.
6>No iconv funcs.
7>No intl/gettext funcs
8>No i18n support and wchar_t.
...
2.Cross compiling troubles such as the typecast of pointers
may be the sin of SIGBUS in ARM,ARM-THUMB troubles,...etc.
Therefore the hacking is mainly focusing on such missings. I suppose you are
familiar with ARM cross compiling and Android NDK development.
Building all glibs
prerequisites
=======================================
1>Android souce build system or Android NDK
for me, I use the android NDK r4c for
Android 2.2 provided by Mozzila
which has nearly full C++ support:
http://ftp.mozilla.org/pub/mozilla.org/mobile/source/android-ndk-r4c-0moz3.tar.bz2
and I have modified Andrew Ross's agcc to extract and use the toolchain from
this NDK:
http://blog.csdn.net/rozenix/archive/2011/02/28/6212994.aspx
2> Cross compile the dependencies of glib2.28.1 onto Android in this order:
1)libiconv-1.13.1.tar.gz:
configured by:
CC=agcc CXX=agcc LD=arm-eabi-ld RANLIB=arm-eabi-ranlib \
PKG_CONFIG_LIBDIR=/data/local/lib/pkgconfig:/data/local/share/pkgconfig/ \
./configure \
--prefix=/data/local \
--host=arm-eabi-linux \
--enable-shared \
make;
make install;
2)gettext-0.18.1.1.tar.gz
configured by:
CC=agcc CPPFLAGS="-I/data/local/include" LDFLAGS="-L/data/local/lib" \
CXX=agcc LD=arm-eabi-ld RANLIB=arm-eabi-ranlib \
PKG_CONFIG_LIBDIR=/data/local/lib/pkgconfig:/data/local/share/pkgconfig/ \
./configure \
--prefix=/data/local \
--host=arm-eabi-linux \
--enable-shared \
--cache-file=arm.cache \
--without-included-regex \
--disable-java --disable-openmp --without-libiconv-prefix \
--without-libintl-prefix --without-libglib-2.0-prefix \
--without-libcroco-0.6-prefix --with-included-libxml \
--without-libncurses-prefix --without-libtermcap-prefix \
--without-libcurses-prefix --without-libexpat-prefix --without-emacs
Make,But the build of gettext may not fully succeed,never mind, I need only
libintl.so
so just make install.
Cross compile glib-2.28.1.tar.gz
=======================================
1. do patching with the glib-android.patch attached in this file
by
#patch -p0 < glib-android.patch
2. write this into the cache file arm.cache:
#cat > arm.cache
glib_cv_stack_grows=no
glib_cv_uscore=no
ac_cv_func_posix_getpwuid_r=no
ac_cv_func_posix_getgrgid_r=no
ctrl-D
3. make sure you have tools such as glib-genmashaller of the correct version
installed in your host machine
4. configured the same as libiconv.
5. remove the -lpthread in gthread/Makefile.
6. change the CFLAGS in agcc,replace "-mthumb" by "-mno-thumb"; make;make install
TODO
========================================
1.Check the patching,especially the definitions from arpa/nameser*.h
2.Write Android.mk for glib to ease its use in NDK/SDK development.
The following is the patch file.
OK，下面是补丁内容，虽然为android上的，但其实有些还是通用的，有一定参考意义：
