First of all i got some problems i using ubuntu 12.04 lts version on wmvare.

1. Problem: $sudo yum install compat-gcc-34-c++ compat-gcc-34

Here is the reason: Setting up Install Process
                                No package compat-gcc-34-c++ available.
                                No package compat-gcc-34 available.
                                Nothing to do

2.Problem: after this command: ./configure --prefix=/home/thomos/bin/htk

i got this lines:config.status: creating HTKLib/Makefile
config.status: WARNING:  HTKLib/Makefile.in seems to ignore the --datarootdir setting
config.status: creating HTKTools/Makefile
config.status: WARNING:  HTKTools/Makefile.in seems to ignore the --datarootdir setting

config.status: WARNING:  HTKLVRec/Makefile.in seems to ignore the --datarootdir setting
config.status: creating Makefile
config.status: WARNING:  Makefile.in seems to ignore the --datarootdir setting

and after it if i want the make all and make install i got this error: HGraf.c:73:77: fatal error: X11/Xlib.h: No such file or directory

That was the main 3 problem.

And after this i got this error when i want run the HTK_Compile_Model.sh: ==./HTK_Compile_Model.sh: 203: ./HTK_Compile_Model.sh: let: not found

I think this problem can be solved after the earlier problems but i dont know how.

Pl help me and thanks.
