Git - Installing git using source code (Compile)

 
Installing git using source (Compile)
1. Remove old git package
$ sudo yum remove -y git

2. Install required tools on your system to complie git
$ sudo yum group install -y "development Tools"

Install other required software tools.
$ sudo yum install -y automake curl-devel gettext-devel openssl-devel perl-devel zlib-devel

3. Download git source code
$ wget https://github.com/git/git.git -O git.tar.gz
# git clone https://github.com/git/git.git
# yum remove git
# cd git

Create configure script. This checks for tools and library to complete build process

Now, compile for binary

As of now,
- We are done with configuration step.
- We have a Make file.
  Make file is a configuration file of instructions for make command to process.
- Make file includes instructions on how to compile the binary.
- At this time, we need sudo or root level access to to install.



 Now let's check the version by typing in git space dash dash version and hit Enter. This should reflect the version we just compiled. We'll be using this version for the rest of this course, as it's the most current.


it may take upto 5 minutes depending speed of your system.
