problem with the use of language model tool kit

[tmt]

I have downloaded the cmu lm tool kit version 2.05 (CMU-Cam_Toolkit_v2). I am working in ubuntu. Going to the src folder gave the command : sudo make install , as this is the step suggested for installation of the toolkit in the readme file, provided along with the tool.
The make step resulted in the following error. please help me to solve this error.

I do not see any error here, those are jsut warnings. Tools were installed properly in bin folder.

I recommend you to use SRILM, it is much more advanced than cmuclmtk.

In case you insist I see you are using old version, I recommend you to update to a newer one.
