交叉编译libnice 需要先交叉编译glib。 所有先讲glib的交叉编译

glib 需要 libffi 和 zlib。
我新建了一个目录，用于编译/home/share/build

libffi

1. 下载 libffi-3.2.1.tar.gz
   http://ftp.gnome.org/pub/gnome/sources/glib
2. 解压
3. 进入 libffi-3.2.1 目录
4. 执行confiure

./configure --prefix=/home/share/build/libffi-3.2.1/install/arm/ \
CC=/opt/hisi-linux/x86-arm/arm-hisiv400-linux/target/bin/arm-hisiv400-linux-gcc \
--host=arm-hisiv400-linux \
--enable-static=yes \
--enable-shared=no

cc 指向的目录我的交叉编译gcc,这里我都只编译静态库

5. make, make install

Zlib

1. 下载 zlib-1.2.8.tar.gz
   http://www.zlib.net/fossils/
2. 解压
3. 进入 zlib-1.2.8 目录
4. 执行configure

export CC=/opt/hisi-linux/x86-arm/arm-hisiv400-linux/target/bin/arm-hisiv400-linux-gcc
./configure --prefix=/home/share/build/zlib-1.2.8/install/arm --static

zlib 的configrue 没有cc的配置，只能通过export

5. make,make install

glib

1. 下载 glib-2.45.3.tar.xz
   http://ftp.acc.umu.se/pub/GNOME/sources/glib/2.45/
2. 解压
3. 进入glib-2.45.3目录
4. 新建文件 vim glib.cache

glib_cv_long_long_format=ll
glib_cv_stack_grows=no
glib_cv_have_strlcpy=no
glib_cv_have_qsort_r=yes
glib_cv_va_val_copy=yes
glib_cv_uscore=no
glib_cv_rtldglobal_broken=no
ac_cv_func_posix_getpwuid_r=yes
ac_cv_func_posix_getgrgid_r=yes

然后保存
5.执行configure

./configure --prefix=/home/share/build/glib-2.45.3/install/arm \
CC=/opt/hisi-linux/x86-arm/arm-hisiv400-linux/target/bin/arm-hisiv400-linux-gcc \
--host=arm-hisiv400-linux \
--disable-selinux \
--disable-xattr \
--disable-libelf \
--enable-static=yes \
--enable-shared=no \
LIBFFI_CFLAGS="-I/home/share/build/libffi-3.2.1/install/arm/lib/libffi-3.2.1/include" \
LIBFFI_LIBS="-lffi -L/home/share/build/libffi-3.2.1/install/arm/lib" \
ZLIB_CFLAGS="-I/home/share/build/zlib-1.2.8/install/arm/include" \
ZLIB_LIBS="-lz -L/home/share/build/zlib-1.2.8/install/arm/lib" \
--cache-file=glib.cache

5. make,make install

libnice

1. 下载源代码
   git clone -b 01.13 https://github.com/libnice/libnice.git
2. 进入目录 libnice
3. 执行./autogen.sh

如果出现错误，看是否 gtk-doc-tools 没装，sudo apt-get install gtk-doc-tools

4. 执行configure

./configure --prefix=/home/share/libnice/target \
--enable-static=yes \
--enable-shared=no \
--host=arm-hisiv400-linux \
LDFLAGS='-L/home/share/build/glib-2.45.3/install/arm/lib -L/home/share/build/libffi-3.2.1/install/arm/lib -L/home/share/build/zlib-1.2.8/install/arm/lib -L/home/share/Hi3531A_SDK_V2.0.2.0_wuhan/mpp/T800x/lib/libSipClass/libnice/lib/' \
LIBS='-lssl -lcrypto -lgio-2.0 -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lgthread-2.0  -lz -lffi'

/home/share/Hi3531A_SDK_V2.0.2.0_wuhan/mpp/T800x/lib/libSipClass/libnice/lib/ 目录里面里面有我已经交叉编译好的ssl，crypto库，不做说明。

5. make, make install
