# This script attempts to install Speex, which is needed by someone who wants
# to enable audio compression when doing online decoding.
#
# Note: This script installs Speex in a non-standard position and leads the test 
# procedure of Speex give out errors. Those errors will not influence the 
# installation acutally. So you can ignore them and call Speex's library correctly.
# I just let it be like this at this moment, and may add a patch to resolve this
# later.
