PROBLEM TO BE SOLVED: To provide a software differential measurement device capable of accurately summing up the number of lines of a newly created program source code in pieces of software being developed simultaneously. SOLUTION: The software differential measurement device is provided with an effective code extraction part, a measurement target configuration specific code extraction part, and a comparison part. In the effective code extraction part, software configurations as pairs of a program source code and compilation setting information are input, and among program source codes contained in the software configurations, codes (effective codes), from each of which a portion to be ignored in compilation work is deleted, are output. In the measurement target configuration specific code extraction part, effective codes as measurement targets and an effective code as a comparison target are input, and among the codes included in the effective codes as measurement targets, codes, from each of which a portion matching a portion of the effective code as a comparison target is deleted, are generated for extracting effective code portions specific to the measurement targets. In the comparison part, two codes are input to be compared mutually, and a difference between the two codes is output. COPYRIGHT: (C)2008,JPO&INPIT
