Install GNU GMP on ubuntu after modifying its source code

I understand that installing GMP library on ubuntu requires sudo apt-get install libgmp3-dev My question is, since GNU GMP 6.1.2 source code files are publicly available over here () . I want to tweak some values in the source code and then compile the code and use it in ubuntu 16.04 . Is there a way to do it ? If so, please can someone help me with that? Thanks a lot!

You should start by reading Ubuntu Packaging Guide and especially part 3. Fixing a bug in Ubuntu .

All your steps in brief:

1. Clone source code of GMP for xenial
2. Make changes in its source code
3. Compile deb-package with your changes
4. Install your patched packages into system with dpkg -i *.deb or apt-get install ./*.deb.
