Having trouble with 'make' command. (pertaining to ddrescue)

[kirol]

knoppix@Microknoppix:~/ddrescue-1.8$ make
c++ -Wall -W -O2 -c -o arg_parser.o arg_parser.cc
make: c++: Command not found

I would have expected "configure" to complain loudly about this, but you don't seem to have the C++ compiler installed. Try "apt-get install g++". Having said that, it seems ddrescue is available from the regular debian package pool (at least on this here stable install). So, unless you know you need a specific version, you can simply "apt-get install ddrescue".Oh, and don't forget to run "apt-get update" before installing.
