How to include gstreamer header files to the Qt Symbian application.
now i got Recipe linkandpostlink error when i include the gstreamer header files in to the qt symbian project.

Eventhough i changed
from the code,
<set name="RVCTLIB" value=""/>
<set name="RW_BASE" value="$(RW_BASE_OPTION)0x400000"/>
<set name="RW_BASE_OPTION" value="-Wl,-Tdata,"/>
To
<set name="RVCTLIB" value=""/>
<set name="RW_BASE" value="$(RW_BASE_OPTION)0x700000"/>
<set name="RW_BASE_OPTION" value="-Wl,-Tdata,"/>
but it shows the same error message.
Give the solution for this if u know..
