To compile a C++ program in Ubuntu, you will need to install build-essential package. You may also need to install documentation from these packages: glibc-doc, manpages-dev, gcc-4.1-doc, libstdc++6-4.1-doc. After that, run this command: g++ and specify all source files as parameters (like *.cpp). If the compiler finds no errors, you'll get an "executable" file a.out in current directory. To change its name during build step, pass -o parameter to g++

Can you help with this problem?
