i am using ubuntu 12.04 .after chmod +x ./configure command,everything has gone well. iam no able to install a program since the 'make' command gives an error as "make: *** No targets specified and no makefile found. Stop."
plz help me.

What is the program? Maybe you don't need to build it from source, it could be available from Ubuntu's repositories.

i am having problem with all programs.it shows same error everytime.

Have you got all the software needed for compiling installed? Run this:
Have you got the libraries you need? Ubuntu splits their libraries into two: runtime and development. You need the ones with the -dev suffix.
And, did you run:
before make?

WHAT is the error.
post it please.

not working...
I've tried ./configure but it shows- 'bash: ./configure: Permission denied'.So i tried chmod +x ./configure..

Ref. post #2 : "What is the program ?"

Please mention a couple of program examples.

And : Not all programs use a 'configure' script.
( The are at least 10 other ways to build software.)

banshee-2.6.0,ircii2.8.2,bitchX,vlc2.0.5,gtk+-3.4.3

Still missing critical information

Are those names you gave even source code ?
just where did you get them from ?
and why not just use your package manager to install the already built ubuntu ".deb" files

just where is the build folder ?
your normal used account NEEDS to have read/write permission to the folder

For that above list every one of them need to have prerequisites built from source , and almost every one of those prerequisites also have prerequisites that also need building .


in the source folder there is a text file called README and INSTALL and or a folder called "doc" with the instructions


Did you do as posted in post #4 ?
install at least some of the required software needed to build programs
--------
sudo apt-get install build-essential
-------


most people build software in there HOME folder
or
in a folder set aside JUST for building software

it needs to be owned BY the normal user



also why build from source
vlc alone will need about 50 prerequisites build FIRST before you can even try to build it from source

I'm sure(?) all those are available in Ubuntu's repositories. Open Synaptic package manager, and browse for them.
