To do this SOFTUNE Workbench has a function for analyzing include dependence For details see Section 1 5 Include Dependencies Analysis Function E Build Function Build function generates a target file by compiling assembling all source files registered with a project regardless of whether they have been updated or not and then by joining all required object files Using this function causes all files to be compiled assembled resulting in the time required for generating the target file longer Although the correct target file can be generated from the current source files The execution of Build function is recommended after completing debugging at the final stage of program development Note When executing the Make function using a source file restored from backup the integrity between an object file and a source file may be lost If this happens executing the Build function again CHAPTER 1 BASIC FUNCTIONS 1 4 1 Customize Build Function This section describes the SOFTUNE Workbench to set the Customize Build function BB Customize Build Function In SOFTUNE Workbench different tools can be operated automatically before and after executing the Assembler Compiler Linker Librarian Converter or Configurator started at Compile Assemble Make or Build The following operations can be performed automatically during Make or Build using this function Starting the syntax check before executing the Compiler

133. y added refer to Section 1 11 Macro Descriptions Usable in Manager CHAPTER 1 BASIC FUNCTIONS 1 3 Project Dependence This section explains the project dependence of SOFTUNE Workbench E Project Dependence If target files output by other projects must be linked a subproject is defined in the project required in Project Dependence in the Project menu The subproject is a project on which other projects depend By defining project dependence a subproject can be made and built to link its target file before making and building the parent project The use of project dependence enables simultaneous making and building of two or more projects developed in one workspace A project configuration in making and building a subproject in Project Configuration Build Configuration in the Project menu can be specified CHAPTER 1 BASIC FUNCTIONS 1 4 Make Build Function This section explains the make build function of SOFTUNE Workbench B Make Function Make function generates a target file by compiling assembling only updated source files from all source files registered in a project and then joining all required object files This function allows compiling assembling only the minimum of required files The time required for generating a target file can be sharply reduced especially when debugging For this function to work fully the dependence between source files and include files should be accurately grasped
