Ubuntu – sqlite installation

Most programs are looking for files they need (like config files, GUI ressources, ...) on a few hardcoded places and will refuse to works if those files aren't there. To change this places you usually need to recompile the programs (but sometimes you can use command line options or environment variables instead).

dpkg and apt offer a way to change the install location (as far as I remember it's --root= with dpkg and Dir::Root in the apt config - but check the docs if you really need it). This is so you can mount another systems's root dir on your system and install packages on it (like if you have diskless systems mounting their root via NFS from a server).

Something's wrong here. I've installed Matlab R2012a, and the install file does not require any input file.

This should work.

Command line way.

• Open Terminal
• cd into Matlab directory ( which has the install file and is shown in your screenshot)
• sudo chmod +x ./install
• sudo ./install
• This will open a window, from where you will be able to proceed yourself.

GUI way:

• type alt+F2. this opens the run dialog
• type gksudo nautilus and hit enter
• open the Matlab directory (as shown in your screenshot)
• check if install file has execute permissions (as in your screenshot)
• Double click install. You will get a window asking you wether to display or run.
• Click on Run
• you should be able to find your way from here. this opens a window with necessary instructions.

as you see, The Command line way is easier and safer.. ;)

This is guaranteed to work. And just so you know, when you executed install, as described in your question, /usr/bin/install must have got executed. It is probably the one that complained of a missing file operand.
