This is a review (flame) of the Lattice C++ compiler. This review is not
concerned at all with the quality of the compiler. It is concerned solely with
Lattice's marketing policy. The Lattice C++ is an entirely seperate product
from their C compiler. This means that the C++ compiler does not come with
any documentation for the C standard library. Nor does the C++ compiler come
with any of the utilities, such as omd, that come with the Lattice C compiler.
I was under the impression that C serves as the base for C++. Further,
I was under the impression that the C standard library is part of C++.
Certainly Bjarne Stroustrup makes use of the standard library in his book, and
for all intents and purposes Stroustrup is C++.
Lattice has told me that I will have to buy their C compiler (going rate is
about $180 I think) if I want to use routines such as strcmp(), strcat(),
sprintf(), sqrt(), sin(), cos(), itoa(), etc. in C++. Considering that I paid
$500 for the C++ compiler, it seems grossly unfair that I must now pay another
$180 just so I can use the C standard library which I believe is also the C++
standard library.
If you have not been able to guess so far, then I will make it clear that
I am very disappointed with Lattice. The implementation of C++ itself seems to
be adequate, but the policies of Lattice leave me feeling very cold.
Fortunately, Lattice offers a 30-day money back guarantee. I may well be
forced to use it.
Oh yes, one more twist to the knife. On the back of the box C++ comes in,
under the section entitled "Package Contents:", one of the items listed is
"Lattice C Compiler".

Could someone with experience using Lattice C++ for the Amiga send me mail on its compatibility with AT&T C++ 2.0? If it isn't fully compatible, is there an upgrade path expected soon? Since there is an educational discount (50% off of list) with Lattice, I was thinking of purchasing their latest C++ and C compilers. thanx -- Roland J.

I haven't seen answers to these questions in comp.sys.amiga
or comp.sys.amiga.tech yet, so I thought I'd post them before
I spend lots of money.
I just bought Lattice C (v5.04), and I noticed that they have a
C++ compiler also. Does anyone know if this is just a translator,
or a full compiler?
I think I'm going to end up teaching Sun C++, and since Sun C++ is
based on ATT cfront v2.0, I need a 2.0 C++. Is Lattice based on
C++ 1.2 or 2.0?
Mikejer@stiatl.UUCP (John Ramspott) (12/22/89)
The Lattice C++ front end is a true AT&T implementation, although is not yet
up to 2.0. Like AT&T's implementation, it is a translator that converts the
C++ into C and compiles it with the C compiler. When you buy C++, you get
enough of the 4.0 C compiler to use it, but you may definitely use it with the
5.x C compiler (which is what I do).
When I got my review copy back around February, I had to pay $50 to
keep it since Lattice pays that much per copy to AT&T as a licensing fee. It is
a true AT&T translator, which makes me feel comfortable since Bjarne Stroustrup
is authoring C++ for AT&T. This implementation is the recommended method for
C++. While this method is slower than a full compiler, it is "the spec".
I also like the fact that I can upgrade the C compiler portion at will,
without having to worry about whether or not Lattice will upgrade its C++
compiler. I can take full advantage of bug fixes and new features of the
frequently updated Lattice C compiler, which I also use by itself a good bit.
I have had little trouble using it. It seems to be a full, robust
implemention. I believe I have managed to excercise most of the major features
of the C++ language (prior to 2.0) with it. The biggest difficulty is debugging
it since CPR only can deal with the intermediate C code. Sometimes the
connection between the C and C++ is obvious, other times I have a hard time
with it. I hope that they come out with a CPR that can work directly with
my C++ source.
My only problem with it is that it is slow to translate -- no disk access,
it appears to have to "think" real hard about things. Knowing the way Lattice
updates things, I am sure that the 2.0 features will put in an appearance. By
the way, Lattice provides some neat classes for doing things with Intuition
and other aspects of the AMiga OS.

If you have5.04, then I think that you can buy Lattice C++ directly from Lattice for $200. At least you used to be able to. It works pretty well, but it does have the cfront 1.1 bugs. Lattice is reportedly working on either porting cfront 2.0 or writing a 2.0 compliant compiler. I certainly hope they have something soon. Barry

I've been using Lattice C++, and I am quite pleased with the size of the executables. The streams package tends to be much larger than stdio (just one of many reasons I stick with stdio, even in C++.) I don't find the resultant executable to be larger than the equivalent program in C. -tom
