help make: command not found

[shishio]

Hi everyone,

Im running Knoppix version 6.7.1 through a USB stick on my laptop in order to recover a hard drive. This is my first time dealing with a Linux system and when i try to use the "make" command i get the message:
"make: command not found".
how can i get "make" to work?

Thanks

Ok, so i managed to install "make" manually but now when i try to use it to install "ddrescue" it tells me "c++: command not found".
I tried doing "apt-get update && apt-get upgrade" and after about 2 hours it finished and threw many "error adding ..." messages but also many "Setting up...." messages.
I then tried running "apt-get install build-essential" and then it threw:
"The following packages have unmet dependencies:
build-essential: Depends: g++ (>=4: 4.4.3) but it is not going to be installed
Depends: make but it is not going to be installed
Depends: dpkg-dev (>=1.13.5) but it is not going to be installed
E: Broken packages"

when i try to install any of those dependencies through "Synaptic" i get errors that they depend on something else and it goes on forever like this.
Isn't there any way to automatically install all dependencies?

There are two programs called ddrescue. One is already present in Knoppix 6.7.1. Its executable is called /bin/dd_rescue. You can find the other program in the Debian package gddrescue (http://packages.debian.org/en/squeeze/gddrescue). Thus I do not think you need to compile the program.
