I'm using Ubuntu 11.04 (VMware). I aim to implement OpenMP. Im using gcc 4.5 compiler. I tried to install it by using the command
sudo apt-get install gcc 4.5.
Afterwards I proceed with
gcc -fopenmp foo.c BUT the output was:
gcc: foo.c: No such file or directory gcc: no input files –.
Now I tried to install the package by using :
ubuntu@ubuntu:~$ sudo apt-get install essential Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package essential.
I also tried apt-cache search essential
and after that
sudo apt-get install essential-dev
But the same error again,
E: Unable to locate package essential-dev
Do I need to download any package? What should I do?
