Abstract: The invention relates to a method for transforming a shared library between two operating systems with different application binary interfaces (ABIs) on a predetermined instruction set architecture. The shared library is implemented by a source object file comprising at least a source memory image, source symbol information, and absolute source relocation information. The method comprises: creating a target object header compliant to the target ABI and comprising information descriptive of the shared library and/or a target object file; creating a target memory image compliant to the target ABI from the source memory image; creating target symbol information compliant to the target ABI from the source symbol information; creating target relocation information compliant to the target ABI from the source relocation information; and writing the target object header, memory image, symbol information, and relocation information to the target object file to implement the transformed shared library.
