libnice依赖于glib，glib编译请参照 https://github.com/since2014/glib4android

稍后我会将编译通过的源代码以及编译出库文件以压缩包方式贴出;

libnice的AndroidDemo会后续抽空写一个。

编译libnice

./configure --prefix="${SYSROOT}/usr" --host=arm-linux-androideabi CFLAGS="--sysroot $SYSROOT" --enable-static --disable-shared LDFLAGS="-static"

make;make install

附glib编译详细步骤：

@https://github.com/since2014/glib4android

  1. 下载源码

a.下载glib-2.34.3

http://ftp.gnome.org/pub/gnome/sources/glib/2.34/glib-2.34.3.tar.xz

b.下载libiconv-1.14

http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz

c. 下载gettex-0.18.2

http://ftp.gnu.org/pub/gnu/gettext/gettext-0.18.2.tar.gz

d. 下载libffi-3.0.12

ftp://sourceware.org/pub/libffi/libffi-3.0.12.tar.gz

  1. 准备工作

a. 设定工作目录（如YOUR_WORKSPACE）, 将上面下载的源码包(.tar.gz, 四个) 解压到$(YOUR_WORKSPACE)/glib-4-android/

b. cd $(YOUR_WORKSPACE)/glib-4-android/

c. ls

==>gettext-0.18.2 glib-2.34.3 libffi-3.0.12 libiconv-1.14

d. 创建临时目录并下载以下两个文件。

e. mkdir tmp

wget -O ./tmp/config.sub "git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD"

wget -O ./tmp/config.guess "git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD"

  1. 准备交叉编译环境

    我的ndk目录: /home/xxx/dev_env/android-ndk-r9d

a. cd /home/xxx/dev_env/android-ndk-r9d

b. build/tools/make-standalone-toolchain.sh --platform=android-14 --toolchain=arm-linux-androideabi-4.6 --install-dir=${HOME}/dev_env/android-toolchain

c. echo "export SYSROOT=${HOME}/dev_env/android-toolchain/sysroot" >> ${HOME}/.bashrc

d. echo 'export PATH=${PATH}:${HOME}/dev_env/android-toolchain/bin' >> ${HOME}/.bashrc

e. source ${HOME}/.bashrc 或 source ~/.bashrc

  1. 编译libiconv

a. cd $(YOUR_WORKSPACE)/glib-4-android/libiconv-1.14

b. 到build-aux目录和libcharset/build-aux目录下备份config.sub和config.guess 为config.sub.bak和config.guess.bak

c. 将$(YOUR_WORKSPACE)/glib-4-android/tmp里的config.sub和config.guess拷贝到$(YOUR_WORKSPACE)/glib-4-android/history_compile/libiconv-1.14下的build-aux目录和libcharset/build-aux目录下，两个目录两个文件都要有

d. 备份libiconv-1.14/configure

e. gl_cv_header_working_stdint_h=yes ./configure --prefix="${SYSROOT}/usr" --host=arm-linux-androideabi CFLAGS="--sysroot $SYSROOT" --enable-static

f. make -j4;make install

g. 编译完后在 ${SYSROOT}/usr/lib/目录下能找到库(libcharset.so和libiconv.so, preloadable_libiconv.so)

  1. 编译gettext

a. cd $(YOUR_WORKSPACE)/glib-4-android/

b. 找到gettext-tools/src/msginit.c, 备份msginit.c==>msginit.c.bak;

找到这行“ /* Return the pw_gecos field, up to the first comma (if any). */”;

将行   fullname = pwd->pw_gecos; 替换为：

	#ifndef __ANDROID__

   			fullname = pwd->pw_gecos;
	
	#else
	
		fullname = "android";
	
	#endif

原因：

android toolchai 的 passwd 结构体没有 pw_gecos 成员，给 fullname 赋值, 避免访问 pwd->pw_gecos。

c. 执行 ./configure --prefix="${SYSROOT}/usr" --host=arm-linux-androideabi CFLAGS="--sysroot $SYSROOT" --enable-static --disable-java --disable-native-java

d. make -j4;make install

e. 编译完后在 ${SYSROOT}/usr/lib/目录下能找到库(libasprintf.so, libgettextlib.so, libgettextpo.so, libgettextsrc.so, libintl.so)

  1. 编译libffi

a. ./configure --prefix="${SYSROOT}/usr" --host=arm-linux-androideabi CFLAGS="--sysroot $SYSROOT" --enable-static

b. make -4;make install

c. 编译完后在 ${SYSROOT}/usr/lib/目录下能找到库libffi.la pkgconfig/libffi.pc

  1. 编译glib, (编译glib2.40, 参见7.1)

a. 新建一个文件 android.cache, 写入以下内容.

# file android.cache

ac_cv_type_long_long=yes

glib_cv_stack_grows=no

glib_cv_uscore=no

ac_cv_func_posix_getpwuid_r=no

ac_cv_func_posix_getgrgid_r=no

b. 配置编译的指令(test 模块编译不过去, 没关系, 用不到, disable 之):

另外

#echo "export PKG_CONFIG_PATH=${SYSROOT}/usr/lib/pkgconfig/" >> ${HOME}/.bashrc

echo "export PKG_CONFIG_LIBDIR=${SYSROOT}/usr/lib/pkgconfig/" >> ${HOME}/.bashrc

原因 PKG_CONFIG_LIBDIR的优先级比 PKG_CONFIG_PATH 高，所以会覆盖PKG_CONFIG_PATH的设置。

$ ./configure --prefix="${SYSROOT}/usr" --host=arm-linux-androideabi CFLAGS="--sysroot $SYSROOT" --enable-static --cache-file=android.cache --disable-modular-tests

c. 打补丁:https://gist.github.com/mathslinux/5283294
