So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear! | |
Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy. | |
* Off the top of my head * | |
1. Fork their repo on Github | |
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it | |
git remote add my-fork git@github...my-fork.git |

on CentOS: | |
1. You need to install PHP’s devel package for PHP commands execution | |
yum install php-devel | |
yum install php-pear | |
2. Next install GCC and GCC C++ compilers to compile Xdebug extension yourself. | |
yum install gcc gcc-c++ autoconf automake |
Let's say you're using Ubuntu 13.04 (Raring Ringtail, released in April 2013) and it just went End-of-Life on you, because it's supported for only 6 months, and the deprecated packages are taken down after 12 months.
You'll probably figure this out the hard way. When you run sudo apt-get update
, it will eventually report these errors:
