I was trying to install the software quicknet from a tar.gz file. After running ./configure, when I tried running make, it showed the following error:

g++ -I. -I. -c QN_args.cc
/bin/bash: g++: command not found
make: *** [QN_args.o] Error 127

I have already installed the gcc compiler.

You need the g++ compiler, not gcc, so install the g++ package, and maybe build-essential for any needed headers:

sudo apt-get install g++

And if necessary (probably not for this package):

sudo apt-get install build-essential

---

You should read the README file(s), then the INSTALL file and follow the instructions. They usually boil down to running configure:

./configure

Then running make:

make

Then, if you want to install the programs in a system area, run:

sudo make install

The configure step should search out the necessary parts (g++) and complain and stop if necessary parts are not found. It builds the Makefile from the information about your system.

I had no issues with the downloaded package, but then again, I do have the build-essential package installed for what I do. g++ gets installed into /usr/bin, which should be a normal part of your PATH.
