I downloaded the "gspca" video for linux (v4l1) driver but when I tried to compile it, the terminal showed the following error:

$ cd gspcav1-20071224/
$ ~/gspcav1-20071224
$ ./gspca_build
bash: ./gspca_build: permission denied

I have no clue why I don't have permission in my own machine.

you need to use the "sudo" command to do certain admin things. try that followed by your password – Magpie Dec 5 '12 at 0:46
Can I ask why you needed to download the gspca driver? What webcam are you using and what version of Ubuntu are you trying? – Luis Alvarado Dec 5 '12 at 1:16
The webcam is ID 0c45:602e Microdia VideoCAM Messenger and i can't make it work. I'm trying ubuntu 12.04 – user112007 Dec 8 '12 at 17:21
I can use the webcam with Cheese but not with skype – user112007 Dec 8 '12 at 18:00

You need to grant execution permissions to the file. There are several ways to allow a file to be executed as a program :

  • Using Nautilus file manager, right click on your script file gspca_build and select Properties. Then go to the Permissions tab and check Allow executing file as program.

enter image description here

  • Using the command line, open a terminal and set gspca_build directory as your current directory. Then type the following command :

    sudo chmod +x gspca_build

You should now be able to execute your script.
