You cannot. You can test-drive it on their web site though

The purchase price is also dirt cheap; something even a student
could afford.

Right. Good price for a high quality product. Nice!

That's in addition to the compiler you must have to turn Comeau's generated
C code to machine code, yes? Why not just use the platform compiler (VC++ on
Windows, for example) in the first place? I don't understand how adding
translation steps and requiring more compilers is good. I could see how many
years ago when there weren't C++ compilers available on most platforms how
that would be good. But today??

You might want a better compiler!

Or more likely, you are using one of the many embedded platforms that
don't have a C++ compiler.

1. I wouldn't call something that translates from one high level language to
another a compiler. (Just like I wouldn't consider cfront one). I'd call
the components that do translation (to intermediate form) that occurs before
the C code generation a compiler front-end.
2. If by "better", you mean "better compliance with the standard", well it
would have to be an awfully critical need for some feature that would cause
one to go from a compiler to a language-to-language translator.
Or more likely, you are using one of the many embedded platforms that
don't have a C++ compiler.
That niche I can understand.

Formally, you're probably correct, but practically, it comes out
to the same thing.
2. If by "better", you mean "better compliance with the
standard", well it would have to be an awfully critical need

Better can mean many things: less bugs, more optimization,
stricter standards compliance... Off hand, Comeau beats VC++ two
out of three there.

Better can also mean portability. One of the strongest motives
I know for using g++ is that I have the same compiler on all of
my platforms. Comeau offers the same advantage, with even
better quality and better standard compliance.

As to "language-to-language translator": Comeau is just using C
as a platform neutral intermediate representation. It's not
really converting C++ to C, at least not to any C you'd ever
want to see. And who cares what intermediate representation is
being used. That's an internal detail of the compiler,
invisible to the user.

"Formally, you're probably correct, but practically, it comes out

How can you consider "the same thing" having to have 2 tools installed
rather than just one to get the same result?
2. If by "better", you mean "better compliance with the
standard", well it would have to be an awfully critical need
for some feature that would cause one to go from a compiler to
a language-to-language translator.
"Better can mean many things: less bugs, more optimization,
stricter standards compliance... Off hand, Comeau beats VC++ two
out of three there."

But Comeau feed into VC++ (or g++), yes? It still seems like you have all
the issues with the platform compiler plus any issues with the front end.

"Better can also mean portability. One of the strongest motives
I know for using g++ is that I have the same compiler on all of
my platforms."

Though using different compilers does help check out your code better.
You'll probably write less portable code and have more bugs within the
safety of one compiler than if you were to build with many.

"Comeau offers the same advantage, with even better quality and better
standard compliance."

But it's still apples and oranges if you ask me because Comeau is not a
"from source to executable" product. It seems like a special-purpose product
to use when you want to code in C++ but one or more of your target platforms
doesn't have a C++ compiler. Yes?

"As to "language-to-language translator": Comeau is just using C
as a platform neutral intermediate representation. "

I don't think that is correct. I think it translates to
platform-compiler-specific C. (Which compilers it uses on which platforms, I
don't know. VC++ on Windows?)

"It's not
really converting C++ to C, at least not to any C you'd ever
want to see."

I don't see how the effects of using multiple compilers/tools wouldn't be
additive as far as the potential issues go. It's just that Comeau abstracts
one away from one set of the issues. But who's to say they're better at it
than you are?

It appears to me that you'd have to be targeting a lot of "weird" hardware
where Comeau is and other C++ compilers aren't, in or to be using the
product. If all your platforms had a C++ compiler or g++, you'd probably use
those/that.

"And who cares what intermediate representation is
being used. That's an internal detail of the compiler,
invisible to the user."

Having TWO intermediate representations doesn't seem good.

Also, there's 2 vendor dependencies: Comeau front end and the platform
compiler. Seems painful: more vendors, more pain. Am I missing some info?
Would you agree that if I was (just) developing GUI programs with wxWindows
on Windows and on FreeBSD/X I would not want to use Comeau?

How can you consider "the same thing" having to have 2 tools installed
rather than just one to get the same result?
Because the end result is the same?

I once used a program that compiled and linked in one program. No need
to compile and link in two steps. But the end result was the same.
Although, there are plenty of situations where two programs, a compiler
and a linker would be better.

Not all the issue with the platform compiler. Because the compilation
process probably creates code that is more likely to compile and run
correctly, probably, in part, by using a subset of the language. I
haven't used this product in particular, but other front ends I've used
have worked that way.
"Better can also mean portability. One of the strongest motives
I know for using g++ is that I have the same compiler on all of

Though using different compilers does help check out your code better.
You'll probably write less portable code and have more bugs within the
safety of one compiler than if you were to build with many.

I suppose that might depend on the conformance of the particular
compilers you are using.

I've seen plenty of code that has things like:

#ifdef GIANT_COMPUTER_ CORP_VERSION_5_ 00
// do something strange
#endif
#ifdef GIANT_COMPUTER_ CORP_VERSION_5_ 01A
// do something even stranger
#endif
#ifdef WOW_COMPUTER_MO DEL_NINE_HAS_36 _BIT_WORDS_AND_ 12_BIT_BYTES
// and you thought the other two were weird
#endif

Or when a particular target doesn't have a a C++ compiler that is
conforms enough to compile your code.

No code is ever perfect. All code has bugs. But Comeau has a pretty
good reputation. If your question stands, then you ought to write in
assembler (ie write something that produces the code you want to run) on
every platform, because who's to say any compiler writer is going to be
better at it than you are.
It appears to me that you'd have to be targeting a lot of "weird"
hardware where Comeau is and other C++ compilers aren't, in or to be
using the product. If all your platforms had a C++ compiler or g++,
you'd probably use those/that.
I suppose that in general compiler compliance is getting better, but
some are more compliant than others.

[snip]
Also, there's 2 vendor dependencies: Comeau front end and the platform
compiler. Seems painful: more vendors, more pain.
Everything is painful. I suppose it depends on what guarantees you get
from each vendor and how much you're paying.
Am I missing some
info? Would you agree that if I was (just) developing GUI programs with
wxWindows on Windows and on FreeBSD/X I would not want to use Comeau?
That seems like it's going to be a somewhat subjective choice to me.
But I suppose a better choice could be made if you'll test the compiler
you are using for compliance and Comeau's and tell us which is more
compliant, (I understand that there are commercial packages available
that will help you with this) and also if those are features of the
language that are important to you, now and in the future.

This is pretty old, from November 2003, but may still be interesting to
you. It's been a long time since I read the article. I wish someone
would repeat this today. Maybe someone has. Does anyone know?

The Comeau C++ web site does not appear to have been updated in nearly a year, but I do notice that Mr. Comeau does post here quite freqently. Is this compiler still being actively developed and updated? Has there just been no news or updates for the past year because the compiler is so very well engineered and constructed?
