configure: error: C++ compiler cannot create executables

Question

I am trying to install Robocup simulator from https://sourceforge.net/projects/sserver/?source=typ_redirect . As mentioned in the README file in the folder to build it I have to execute /.configure but I get this error.

Now when I checked my g++ compiler.

saurabh@saurabh-GL502VM:~/intelligent_systems/project/rcssserver-15.3.0$ g++ -v
The program 'g++' is currently not installed. You can install it by typing:
sudo apt install g++

But when I tried to install g++ compilier I got this:

saurabh@saurabh-GL502VM:~/intelligent_systems/project/rcssserver-15.3.0$ sudo apt install g++
Reading package lists... Done
Building dependency tree

g++ is already the newest version (4:5.3.1-1ubuntu1).
The following packages were automatically installed and are no longer required:
  cpp-4.8 libcloog-isl4 xserver-xorg-legacy
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 7 not upgraded.

Now, what should I do to install the the simulator? Thanks!

Answer 1

apt-get can find multiple versions of g++, and even install them side by side. But clearly "g++" on the command line must be a shortcut to only one of them. You can change that shortcut with sudo update-alternatives --config g++.
