编译gstreamer相关

把编译完的配置从config.log里拷出来，去掉双引号了，记得加上

gstreamer统一目录是/home/gstreamer,编译后统一安装在/home/gstreamer/install文件夹里，所以设置pkgconfig就只用设置一个地址
export PKG_CONFIG_LIBDIR=/home/gstreamer/install/lib/pkgconfig

然后开始编译
/home/gstreamer/gstreamer-0.10.21/

/home/gstreamer/glib-2.18.3
$ ./configure --cache-file=arm.cache --host=arm-linux --prefix=/home/gstreamer/glib-2.18.3/install
arm.cache的内容在前面的文章里写了。家里用X86_64编译的，把posix那2个设置为no，可以编译过了。也没有WARNING提示了。

/home/gstreamer/libxml2-2.6.24/
$ ./configure --host=arm-linux --prefix=/home/gstreamer/libxml2-2.6.24/../install/

修改的configure文件在前面文章里写了

这里的编译都是不带额外的plugins，比如没有把mad加进去

运行时设置环境变量GST_PLUGINS_PATH为包含plugin的地址
在没有设置该环境变量时，运行/home/gstreamer/gstreamer-0.10.21/tests/examples/helloworld/.libs下的helloworld程序会报错：

# ./helloworld a
**
ERROR:helloworld.c:59:main: assertion failed: (filesrc)
Aborted

本 来是件简单的事情，设置环境变量就行了，但是网上没搜到解决办法，加入了gstreamer的QQ群，也没人告诉我。有个人倒是算热心回答我问题，但是他 觉得这里不应该出错，他不会在这里出错。那么他们怎么把有哪些plugin告诉gstreamer的？可能办法不一样吧。结果我找到一 篇"GStreamer Plugin Writer's Guide(0.10.21.1)"，Chapter 9. Building a Test Application才知道要设置GST_PLUGIN_PATH
