升级ubuntu14.04 bluez版本至5.25

环境介绍：ubuntu14.04 简易安装 bluez4.101

安装编译思路

1.由于我不知道5.25的依赖环境，所以我首先安装bluez5.25

./configure --prefix=/bluez/

configure: error: GLib >= 2.28 is required

1. 根据报错，安装glib 2.30 

下载地址：http://ftp.gnome.org/pub/gnome/sources/glib/2.30/

./configure --prefix=/bluez/

configure: error: *** Working zlib library and headers not found ***

2. 根据报错，安装zlib 1.2.11  

下载地址：http://zlib.net/fossils/

./configure --prefix=/bluez/

make

make install

3. 安装zlib成功,安装glib

./configure --prefix=/bluez/

configure: error: *** Working zlib library and headers not found ***

4. 系统报错，重新安装glib （选择加载的的include文件和库）

./configure --prefix=/bluez/ CFLAGS=-I/bluez/include LDFLAGS=-L/bluez/lib

//CFLAGS=-I include目录  CPPFLAGS（c++）

//LDFLAGS=-L库目录 

configure: WARNING: zlib.h: accepted by the compiler, rejected by the preprocessor!

configure: WARNING: zlib.h: proceeding with the compiler's result

configure: error: Package requirements (libffi >= 3.0.0) were not met:

No package 'libffi' found

5. 根据报错，安装libffi3.0.13

下载地址 ftp://sourceware.org/pub/libffi/

./configure --prefix=/bluez/

make

make install

7安装glib

./configure --prefix=/bluez/ CFLAGS=-I/bluez/include LDFLAGS=-L/bluez/lib

还是NO find libffi

export PKG_CONFIG_LIBDIR=/bluez/lib/pkgconfig  //执行这句使编译器寻找到对应的库

8.glib安装成功，继续安装bluez5.28

./configure --prefix=/bluez/ CFLAGS=-I/bluez/include LDF
