By default, Ubuntu 10.04 and 10.10 is installed without a developer's tools. So if you're a C++ programmer or just someone who needs to execute the "make" command using the terminal but encountering error like the example below:
make: g++: Command not found
Then all you have to do is run the following command in your terminal:
sudo apt-get install g++
When you encounter the said error, it only means that you have lack of compiler to compile the source codes. Just by installing g++ will do the trick.
Happy Coding :)
