Compile a project after modification

[Sonic]

I have an Linux open-source and I have to edit a source in the project. My problem is that after the change I do not know how to recompile the project. I have a makefile but when I run it I see the following message: "nothing to do for all"?

Try

make clean

Then

./configure - help

for configuration options

./configure # + configuration options 
make 
make install

I think I misstated my problem ...

My program is in several source quote, I do not want to recompile the whole program but only one source that calls to other sources

Example: the project consists of (main.c, source1.c source2.c, ... etc). I want to compile and run only source2.c since it depends on other sources in the project.

Sorry if I did not explain the problem

Normally if you simply change a source file and you do make it should help.

It will generate .o of .c, which then changed the link again to get the program

- Did you tried to rebuild the binary recompiling sources before making the modification?
- The program is multi-platform?
