Abstract: A language interoperation method and apparatus, a storage medium, and a program product are provided. The method includes: obtaining code in a first language and code in a plurality of second languages (S1); generating a unified abstract representation of interoperation boundary information of the plurality of second languages based on the code in the plurality of second languages (S2), where the unified abstract representation is binary code of the interoperation boundary information of the plurality of second languages, and the interoperation boundary information of the plurality of second languages represents constituent elements allowing mutual access or use with the first language among constituent elements of the plurality of second languages; and compiling the code in the first language based on the unified abstract representation, to obtain and output binary code of the code in the first language (S3).
