- This is a good product on the whole. I would recommend it to anyone who
- has an interest or need for C++. The compiler is mature and stable, and
- well tested. The driver needs major work but that is on the way and NOT
- fatal. Out of a score of 100 this is an 80, and worth the $250.

- (c) 1991 Kenneth Jamieson
-
- The following is a review of the Comeau Computing C++ compiler. Info
- on how to order and where to contact the company are at the end.
-
-
- Well, as anyone who has worked with C++ in any form knows, this
- language and the Amiga were meant for each other. The Amiga's GUI interface
- is very clean to start with in most cases, and all GUI's are a perfect
- candidate for the object features in C++.
-
- The one previous attempt to bring C++ to the Amiga was by Lattice
- Inc. in 1988. That effort was a failure because of many reasons. One of them
- is that the Amiga world was still un-aware of C++ (as was most of the
- world). Now, with the fate of the Amiga and Unix tied together, it is time
- to look at this again. C++ is (arguably) becoming the language of choice
- for Unix GUI programmers... and Amiga programmers are starting to hear the
- term more and more.
-
- Comeau C++ is NOT a complete development system. The 250$ price
- gives you the Amiga binary for "Cfront 2.1", AT&T's C++ -> C translator.
- This is the standard method of writing in C++ under Unix as well. You get the
- needed header files and so on as well. This means that you need SAS/C 5.10a
- to use this product. It will also generate ANSI style C, and so any good
- ANSI compiler should be able to replace SAS/C. In addition, it should be noted
- that if you have the Lattice C++ product, the "cpp" pre-processor can be
- used to enhance your productivity. Comeau has stated that they will be
- releasing their own pre-processor soon, and that you can also use the one
- that comes with SAS/C in most cases.
-
- The distribution is on one floppy disk, and is no real problem to
- install. My disk had an error on it in the Install program, so I had to
- do it by hand. The process is simple and fast.
-
- The packaging of the product is adequate. There is a binder that
- has the product specs and language information, and a insert with the
- Amiga instructions.
-
-
- ************
- INSTALLATION
- ************
-
-
- The product installs in a painless manner, and I gather the
- Install program would have made it easier.
-
- The steps are:
-
- 1) Make a directory for the compiler.
-
- Make a SEPARATE directory tree for this product, it does
- NOT replace any of your SAS/C files.
-
- 2) Install the files.
-
- By hand or with the Install program.
-
- 3) Make assigns.
-
- The Install program will help, but basically there
- are a few you need...
-
- CC21c: - All the executable programs
- CC21lib: - The libraries
- CC21include: - The include files
- QUAD: - Should already be here for SAS/C anyway.
-
- 4) Add CC21c: to your path.
-
- Self explanatory.
-
- 5) Run the "include" program.
-
- You have to do this once. Comeau does NOT distribute a full
- set of header files. This program will take your existing
- C header files and "C++"-ize them.
-
- 6) Copy "como.rexx" to "REXX:"
-
- The compiler is driven by a Arexx program.
-
- 7) Test the compiler.
-
- Go to an example directory and use "como"....
-
- cd ccTest
- como cctest.c
- cctest
-
-
- ************
- COMPILER
- ************
-
- NOTE !! NOTE !! NOTE !!
-
- This portion of the review applies ONLY to the Arexx driver, and
- so should NOT be taken as a reflection on the "cfront" port. All the
- problems in here can be overcome by some Arexx programming (watch for my
- driver soon) and, while annoying, are NOT fatal.
-
- The "como" command is the hub of the compiler. Those using C++
- can equate this to a "CC". And there is problem number one. It doesn't act
- ANYTHING like CC. This will make it difficult for anyone who is new from the
- UNIX world.
-
- In addition, "como" is just not good enough to do real production
- work with in my opinion. It is a good example of Arexx programming
- though and easy to modify so this can be overcome.
-
- The problems are ...
-
- 1) No mixed language compiles.
-
- All source files must be named "*.cp"
-
- 2) Non-standard command line options.
-
- This was livable under SAS/C, there was no standard for
- command line options. But with a C++ product, there is
- a standard.... AT&T. It should be used.
-
- 3) No support for libraries on the command line.
-
- This is not really forgivable.
-
- 4) No support for .o's on the command line.
-
- See point #3.
-
-
-
- So let's face fact folks, this Arexx script needs a major
- overhaul. Now, this is a serious problem, but NOT fatal. I overcame
- most of the problem with a weekend of Arexx hacking... but it was silly to
- do that to get use out of a 250$ dollar product.
-
- The supplied driver is ok for basic hello world types, but write
- your own driver or makefile for real work.
-
- NOTE: I spoke with Greg at Comeau, they are aware of this, and there
- is a free upgrade policy in place for the pre-processor and a new driver
- when it shows up.
-
- NONE of these problems are inherent. In other words, cfront can take
- C or C++ files, and .o and libraries can be linked in, but the Arexx script
- doesn't understand that.
-
-
-
- ************
- LANGUAGE
- ************
-
-
- This is the good side.
-
- This is a 100% complete AT&T 2.1 port. Multiple inheritance and
- all the other features of "real" C++ are supported. There are no new bugs that
- aren't also in the UNIX world, and this compiler is a good way to gain
- experience in a language that will make you a valuable employee at a new
- job and look good on your resume.
-
- I ported and compiled a complicated Unix program I had written, that
- compiles 6 mixed C and C++ files into two libraries, compiles two more
- test C++ programs and links them with the libraries.
-
- After I had hacked the Arexx script into a usable if ugly form,
- it all went along without a hitch. Prefect.
-
- There are by the way, no Amiga specific classes in the
- compiler. This is straight C++. You can use the Amiga with the normal C
- calls and interface, or write your own class library for it.
-
-
-
- ************
- OVERVIEW
- ************
-
- This is a good product on the whole, and we desperately need a full
- C++ 2.1 on the Amiga. I would recommend it to anyone who has an
- interest or need for C++. I would DEFINITELY tell anyone with Lattice C++ to
- get it.
-
- The compiler is mature and stable, and well tested. The driver needs
- major work but that is on the way and NOT fatal. Out of a score of 100 this
- is an 80, and worth the $250.
-
- The company is nice, and UPS Blue shipping is free. COD or
- prepay check are needed for ordering. The technical support is fantastic when
- I needed details on the como.rexx driver, they listened well to my suggestions,
- and kept me informed about my order status.
-
- Have fun!
