Your makefile is wrong. It's compiling all the C files together instead of all the objects. Which, while it will work, is awkward and hard to debug, avoids all the advantages of using a makefile in the first place, and does all the work twice.

Instead of
Code:
cc file.c file2.c file3.c ... -o exec

it should do
Code:
cc file.o file2.o file3.o ... -o exec

Some of those missing functions are functions you still haven't compiled, but a few are from the C math library. At the top of your makefile, add the line:
Code:
LDFLAGS=-lm

That will tell it to link in the math library.

If you're still missing functions, you're missing a file. Maybye whoever gave you the code didn't give you all of it.

Thank you very much the code is working very well now. You make it successful. I appreciate so much all your efort and sharing of knowledge.

Acctually all files are completed. I have test the codes in my friend's notebook last three month ago before I bought my notebook and it work without any problem. However, when I bought my own notebook and install linux then all this problem start to come out. By the way my friend is using suse 10 and I am using suse 9.3. I am not sure if that can make any different.

I have one concern to ask you. After add -lm to the makefile, there was only one warning appeared saying this:

/tmp/ccYaBtHR.o (.text+0X33): In function 'get_boolean':
util.c:warning: the 'gets' function is dangerouns and should not be used.

To avoid this warning what I do, I went to util.c file and comment out gets(line); then the program work very well. Any idea why this warning. Is possible to run the program without commenting out this line?

Again thank you very much
