appsrc undefined reference to 'gst_app_buffer_new'

[Jun Zhang]

Hello,

I am trying to use appsrc to get data from my C application and met
following problems.

 1.undefined reference to `gst_app_buffer_new'
 2. undefined reference to `gst_app_src_push_buffer'
 3.undefined reference to gst_app_src_end_of_stream

After searching for a solution, I saw someone suggest add -lgstapp-0.10
into the make file: Following is the commands in the make file.
export
PKG_CONFIG_PATH=/root/targetfs/opt/gstreame/lib/pkgconfig:$PKG_CONFIG_PATH

/root/CodeSourcery/Sourcery_G++_Lite//bin/arm-none-linux-gnueabi-gcc
-lgstapp-0.10  `pkg-config --cflags --libs gstreamer-0.10`-o syn test_syn.c

And then I have following compile errors. However, i did check and found
that the missing libgstbase-0.10.so.0 is in the same place with
libgstapp-0.10.so.

Any suggestions?
