Cross-compiling, by a multi-version compiler, may produce complied code targeted to a specified release version of a programming platform supported by the compiler. The specified version may be different from a default version of the programming platform targeted by the compiler. Thus, the multi-version compiler may cross-compile source code to generate compiled code for different versions of the programming platform. A developer may specify the target version using a single compiler option and the compiler may, in response, cross-compile for the target version without requiring any additional options to be configured by the user. The multi-version compiler may include library data regarding multiple versions of the programming platform, preventing a developer from having to locate and provide the necessary library data for each targeted version.
