Ubuntu 下编译libjingle-0.6.14

http://blog.csdn.net/feifei454498130/article/details/8197103

添加依赖库:

sudo apt-get install build-essential expat libexpat1-dev libssl-dev pkg-config

sudo apt-get install libssl-dev

sudo apt-get install libpulse-dev

sudo apt-get install libdbus-glib-1-dev

sudo apt-get install libgtk2.0-dev libgnome2-dev

sudo apt-get install libasound2-dev

1、 python 2.4+  因为swtoolkit只能工作在Python 2.x版本, 所以不能安装Python 3.x版本.
2、libjingle库 libjingle-0.6.6 http://code.google.com/p/libjingle/
3、 swtoolkit: swtoolkit.0.9.1  http://code.google.com/p/swtoolkit/ 

4、 srtp: http://libjingle.googlecode.com/files/srtp-cvs.zip

解压到libjingle/talk/third_party/srtp
5、scons : scons-2.0.1-1

解压到libjingle目录下新建scons-local

6、gtest:http://code.google.com/p/googletest/downloads/list 

解压到libjingle/talk/third_party/gtest/

7、expat-2.0.1: http://sourceforge.net/projects/expat/files/expat/2.0.1/expat-2.0.1.tar.gz

解压到libjingle/talk/third_party/expat-2.0.1/

以上准备完了：

export SCONS_DIR=libjingle-0.6.14/scons-local/scons-local-2.0.1

export PATH_TO_SWTOOLKIT=解压后swtoolkit.0.9.1 的目录位置

运行 talk/third_party/expat-2.0.1/configure 与 talk/third_party/srtp/configure.

cd libjingle/talk

在talk目录下，编译：$PATH_TO_SWTOOLKIT/hammer.sh

常见编译错误:

有些库没安装，根据英文提示然后apt-get install 就可以了

./main.scons  将－Werror注释 

-->all warning to error

./talk/session/phone/v4llookup.cc   添加头文件 #include <unistd.h> 

-->::close not declared

./talk/base/openssladapter.cc  添加头文件         #include <unistd.h>

-->mutex_bufwas not declared

---g_thread_init 在 gthread-2.0 库中，在 pkg-config 中除了 gtk+-2.0 之外还需要加上 gthread-2.0 一项。
修改文件libjingle.scons 
talk.Library(env, name = "videorenderer",
             lin_srcs = [
               "session/phone/gtkvideorenderer.cc",
             ],
             lin_packages = [
               "gtk+-2.0",
               "gthread-2.0", //增加
             ],
)
