I want to create a makefile that will compile my objects and name them according to the Linux distro (e.g. Suse, RedHat, or Ubuntu). How can I detect if the OS is Ubuntu or not?

got it working? (since you deleted your comment :D) –  Rinzwind Apr 8 '13 at 10:03
yes, I changed the OS var to be "shell lsb_release -si" and now it works well :). Thanks you for your answer! –  RRR Apr 8 '13 at 11:04
+1 for the funny title. (hint: Makefile and Make file mean totally different things.) –  Mahesh Apr 8 '13 at 14:11

We use cat /etc/lsb-release for identifying the Ubuntu release:

sh-3.2$  cat /etc/lsb-release

For other releases it might be

ls /etc/*release

Gentoo, RedHat, Arch & SuSE all have a release file: These is a complete script in the link ;)

Example code for operation system, architecture and version for Ubuntu type systems:

OS=$(shell lsb_release -si)
ARCH=$(shell uname -m | sed 's/x86_//;s/i[3-6]86/32/')
VER=$(shell lsb_release -sr)
