-
- I. What is it ?
- ------------
-
- GccOpts is a program that allows you to automatically and quickly write a
- Makefile for the Amiga GCC. It's simple enough, I hope, not to need any
- documentation, so don't be too much disturbed if I don't offer you
- megabytes of precise informations about this program (anyway I am reachable
- thru many net-addresses).
-
- This program provides you a useful and graphical interface to easely make
- your Makefiles for Amiga GCC. It needs AmigaOS 2.0 or +, and of course the
- ixemul.library. An example of a project with a graphical interface is
- provided in the package (see Example), have a look on it if you really
- don't know how works a makefile.
-
- Just install it in your path, and enjoy (yes, this is real
- plug-and-play :))
-
-
- What is a makefile ?
- ------------------
-
- A "makefile" is a scriptfile that describes your project (the different
- componants of your program: c files, includes, objects files, libraries,
- etc).
-
- This file (which may be called makefile, or Makefile, or GNUMakefile)
- will be used by a program, called "make", whose job is to always keep your
- project correctly updated. So, if the program does not exist yet, it will
- simply compile it entirely. Or else it will compare the date and time of
- the source file with the date and time of the compiled file, and will
- compile it if,and only if, needed. All of this according to the rules
- described in the makefile.
-
- This provide a very powerly and easy-to-use developping system for the
- programmer.
-
-
-
-
-
-
- II. How the does it work ?
- ----------------------
-
- Firstly you should install GccOpts by copying it to the gnu:bin/
- directory.
-
- Launch GccOpts from the CLI or the Workbench, and have a look on the panel
- that just opened on the screen. On the right, a group named "Project"
- contains a listview and some other gadgets. There are also two other
- groups, "Libraries" and "Options". You'll have to refer to the concerned
- section of the manual for further information about each of this groups.
-
- After having filled some gadget with some random value of your own, press
- the gadget "Save Makefile", and the GccOpts will save a Makefile which
- purpose is to make you compile your project with the gnu Make command.
-
- If you don't want to save the Makefile you have done or modified, just
- click on the "Cancel" gadget or on the upper-left CloseWindow gadget.
-
-
-
-
-
- III. The "Project" group.
- --------------------
-
- In this group, the programmer (you!) will need to give some useful
- informations about the project he (you, ever) want the Makefile to be
- done for.
-
- First of all, the "Project" listview must contain all the files that are
- part of the projet. The given files can be any *.c or *.o file (GccOpts
- will process them differently in the makefile, however). Include files
- are accepted, and gcc will be told to use them, with the directive under
- the form :"-i your_include.h -i another_include.h"... If you add any *.o or
- *.a file in the project listview, it will be added to the Makefile as an
- archive that should not to be deleted by the "clean" rule.
-
- To add a name into the listview, just type it inside the string gadget
- below, and press enter. To delete one entry, select it with the mouse, and
- click on the DEL gadget below the listview. The gadget "?" will pop up a
- filerequester, and if you select a file with it, this one will be added to
- the listview. You can also let the program automatically choose the project
- files, by clicking the "SCAN" gadget. GccOpts will then scan all the files
- in the current directory, and insert in the listview every .c file.
-
- Three cycle gadgets below the listview can be used to select some options
- about the code generation. This gadgets are :
-
- "Code" : which refers to the processor your project will be generated
- for : 68000 - 68020 - 68030 - 68040/020-881 - 68040.
-
- "Fpu" : only allows two value (could have been a boolean thing), fpu or
- not : 68881 or NONE, default is NONE.
-
- "Optimize" will permit to select the level of optimization for your
- program : NONE, LEVEL 1, LEVEL 2, or LEVEL 3. Choose it in peace with
- your concience and your memory (and you'll need some for the third level).
-
- Another, last but not least, gadget allows you to select the name of the
- output file. So the name of the gadget, you'd have guessed it, you clever
- programmer, is "Output". The name you give it will be used as the first
- rule of the Makefile, so that "make NAME_OF_YOUR_PROGRAM_IN_OUTPUT" will
- just compile all the newer part of your project. This is the same than
- "Make" alone, as this is the first rule of the Makefile.
-
- That's all for the "Projet" group.
-
-
-
-
-
-
- IV. The "Libraries" group.
- ----------------------
-
- This group contains only one gadget, a listview, into which the clever
- programmer will put the names of all the libraries that its project will
- need to be linked with. To know how to add an entry to the listview, please
- refer to the previous "Project group" section.
-
- The name of the library can be either the normal file name, ie.
- "libamiga.a" (without quotes) , or either "amiga". "libamiga" will also be
- accepted. This names will be inserted into the project as libraries, and
- will be refered in the Makefile as "-lamiga".
-
-
-
-
-
-
-
- V. The "Options" group.
- -------------------
-
- This group contain a listview that will contain some of the options you
- can need for your project. To flag or un-flag an option, just go onto the
- listview gadget, and click on the option you want to select/deselect. An
- option is currently selected if a "*" is added at its beginning.
-
- This options are divided into 6 parts : Code generation, Linking, Stack,
- Optimizing, Debugging, and Warning. For more information about them,
- please read the gcc documention (click here -->READ GCC.GUIDE to do so).
- However, Names are quite clear, you shouldn't have problems with them, and
- if you have, you can contact me for more informations.
-
-
-
-
-
-
-
- VI. The Makefile.
- -------------
-
- The generated Makefile should not be modified if you want it to be
- correctly re-processed by GccOpts. The makefile should be run by the Make
- command.
-
- This Makefile contains three useful entries for the clever programmer :
-
- - all : This rules will call the two others, clean and compile, and your
- project will be fully recompiled.
-
- - clean : this will clean-up the project, ie. just remove every *.o file
- leading around.
-
- - YOUR_PROJECT_NAME : will recompile only the new or modified files,
- and create an executable named YOUR_PROJECT_NAME, according to the
- informations and options given. The program will recursively scan the given
- c-source file for non-system include files (the token " #include" should be
- at the beginning of the line, with no blank or tabulation). Non-system
- include files are those bracketed with \" (while standart system includes
- should be bracketed with '<' and '>', and won't be scanned). All this
- includes will be linked to the correct c files that call them.
-
- The default rule executed by Make (alone) is YOUR_PROJECT_NAME. In order to
- be able to re-read it correctly, GccOpts puts special informations inside
- the created Makefile, so don't modify it if you want to re-use later the
- result of your (not so) hard work.
-
-
-
-
-
-
-
- VII. The example.
-
- A very simple example is provided, and will quickl show you how GccOpts
- works. The program to compile is simply an "Hello world", and has strictly
- no importance. If Gccopts is not installed in your system, you should copy
- it in the gnu:bin/ directory.
-
- In the workbench screen, open the drawer "GccOpts_Example", and click on
- the Options icon. This icon will call the GccOpts program (which should
- already be installed in the gnu:bin/ or C: directory).
-
- There you can modify the compiler options. Once done, just click on the
- "Save Makefile" gadget. The makefile will be saved, and the program will
- close its window and shut down. Then, you can double-click on the
- MakeProject icon. This script will open a shell window and call the make
- program.
-
- You can also start GccOpts from a shell, and do just the same as above.
- To compile the project, just type "make" or "make all" in the shell.
-
- Please note that the program will be recompiled only if the c-source file
- is modified.
