Have you tested your compilation before using it to simulate the band diagram?
I suggest you to perform an automatic running test and be sure that your compilation is OK you can find how to do it using the link below:
When you run this automatic run you may check the 'runtest.result' to be sure there is no problem with your compiled version before using it.

- Dear Sir,
Thank you very much for your reply. I have run the test, and the runtest.result is here:
1 input_example/Benzene.dat Elapsed time(s)= 18.44 diff Utot= 0.000000000000 diff Force= 0.000000000001

8 input_example/Graphite4.dat Elapsed time(s)= 17.87 diff Utot= 0.000000000000 diff Force= 0.000000000000

14 input_example/Ndia2.dat Elapsed time(s)= 17.32 diff Utot= 0.000000000000 diff Force= 0.000000000000
Total elapsed time (s) 743.36
It seems that the input example GaAs.dat didn't completed well. I have increased the max.iter to 150, yet the result is same. Now Sir, please tell me, what should I do now ?

As you can see from the input of the GaAs.dat, the Band.dispersion keyword is on and from the test result you see that your compiled version do not work well for this example, so there is no wonder why you do not get the correct band structure of Diamond as you stated in your first question.
I think you need to compile your code again with different compilation settings, you may find some useful data at this link:
I suggest to run the automatic tests after your compilation to be sure that your compiled version has no problem before using it for your calculations.
