38 CHAPTER Getting Started
Adapting Prep.bat
Prep.bat is called at the beginning of Makelib.bat. As described above its job is to
set the environment variables for the used tools and the environment variable PATH,
so that the batch files can call the tools without specifying an absolute path. Assuming
the compiler is installed in the folder C:\MTOOL the file Prep.bat could look as follows:
@ECHO OFF
SET TOOLPATH=C:\MTOOL
REM ******************************************************************
REM Set the variable PATH to be able to call the tools
SET PATH=%TOOLPATH%\BIN;%TOOLPATH%\LIB308;%PATH%
REM ******************************************************************
REM Set the tool internal used variables
SET BIN308=%TOOLPATH%\BIN
SET INC308=%TOOLPATH%\INC308
SET LIB308=%TOOLPATH%\LIB308
SET TMP308=%TOOLPATH%\TMP
Adapting CC.bat
The job of CC.bat is to compile the passed source file and adding the file name of the
object file to a link list. When starting MakeLib.bat it creates the following subdirectories
relative to its position:
Directory Contents
Lib This folder should contain the library file after the build process.
Temp\Output
Temp\Source
The object file should be created (or moved) to Temp\Output. This makes sure all the
output will be deleted after the build process. Also the link list should be located in
the output folder. The following shows an example for the Mitsubishi compiler:
@ECHO OFF
GOTO START
REM ******************************************************************
REM Explanation of the used compiler options:
-silent : Suppresses the copyright message display at startup
-M82 : Generates object code for M32C/80 Series (Remove this switch
for M16C80 targets)
-c : Creates a relocatable file (extension .r30) and ends processing
-I : Specifies the directory containing the file(s) specified in #include
-dir : Specifies the destination directory
-OS : Maximum optimization of speed followed by ROM size
-fFRAM : Changes the default attribute of RAM data to far
-fETI : Performs operation after extending char-type data to the int type
(Extended according to ANSI standards)
:START
REM ******************************************************************
REM Compile the passed source file with the Mitsubishi NC308 compiler
NC308 -silent -M82 -c -IInc -dir Temp\Output -OS -fFRAM -fETI Temp\Source\%1.c
REM ******************************************************************
REM Pause if any problem occurs
IF ERRORLEVEL 1 PAUSE
REM ******************************************************************
REM Add the file name of the object file to the link list
ECHO Temp\Output\%1.R30>>Temp\Output\Lib.dat
Adapting Lib.bat
Should contain all the compiler output and the link list file. Will be deleted after
the build process.
MakeLib.bat uses this folder to copy all source and header files used for the
build process. Will be deleted after the build process.
After all source files have been compiled Lib.bat will be called from MakeLib.bat.
The job is to create a library file using the link list created by CC.bat. The destination
folder of the library file should be the Lib folder created by MakeLib.bat. The following
shows an example for the Mitsubishi librarian:
