AWS install problems

Hello, I'm trying to install the AWS package so that I might try eMail access from an Ada program, I'm using GNAT/GPS 2005 under Sidux 2009-4 I apt-get to installed the various GNAT AWS files from the Debian repository without problems, however when trying to access the AWS functions I encountered a few problems. Note: I have setup the two export variables thus: brett@sidux94:~$ export declare -x ADA_INCLUDE_PATH="/usr/share/ada/adainclude" declare -x ADA_OBJECTS_PATH="/usr/lib/ada/adalib" I also included the /usr/share/ada/adainclude in the GPS Project Properties 'source files' list

Web browser in Ada

There are discussions from time to time, since very long, about writing a Web browser in Ada. The main idea would have a safe browser. Actually today's issues about security in Web browsers remarkably seem of the same kind as ten years ago, just a bit more frequent and acute. Did someone give a try ? I guess the following libraries would be considered: - AWS, for the HTTP requests - GtKAda, for a portable GUI - the least possible bindings and the most possible Ada code for decoding images and other contents _________________________________________________________ Gautier's Ada pro

Autoconf & gnat Help Needed

Has anyone here had experience using GNAT with autoconf/automake? I'm attempting to port my autoconf from the original bdbbasic project to the Ada rewrite project (z9basic). But I am having much difficulty getting autoconf, automake and libtool to work together for a gnat build. In a nutshell, I have some static library modules built from: lib_LTLIBRARIES = libz9.la libz9_la_LDFLAGS = -static -version-info 1:0:1 libz9_la_SOURCES = misc.c terminal.c grammar.c parse.c cores.c ccmain.cc This works OK, and produces libz9.a as expected. But the problem is, I need to coax

InformationWeek Gives Ada Black Eye

All this feature richness is great, but at some point it runs the risk of feature bloat, bogging down resources and performance in the process. Remember the Ada programming language? Oft described as having everything including the kitchen sink, Ada was ahead of its time with object- oriented and other capabilities. But its plet

Help - removal from asiswg-members.html

I am desperately trying to get my contact information on http://www.sigada.org/wg/asiswg/asiswg-members.html removed. A long time ago, I naively provided my corporate email address, which I now would really like to have removed. I've followed the "LISTSERV@ACM.ORG" directions, and it tells me I am off of the list. Yet all of my contact information remains on the above page. Does anyone know who I can contact about this? I get bounced trying to contact "ClydeRoby@ACM.Org". You can reply directly with the attached gmail address (I'm not too worried about that one).

Hexadecimal and stream element arrays

I have some data coming in from a serial port which I want to convert to hexadecimal and display on the screen. I was wondering if anyone knows of a simple way to do this?

type String_Type array(Integer range <>) of Character;

I am looking for some sound Ada ('05) advice on a design issue, concerning strings. In my basic interpreter, I permit the end user to choose the array subscript ranges just like in Ada. But this includes strings, whereas in Ada one generally just uses the String type, with its positive subscript values. I would find it convenient in the interpreter to use a string type with an Integer range for Basic string variables instead: type String_Type is array(Integer range <>) of Character; This allows subscripts to range negative to positive. The reason for this appr

A new notion: stronglly-typed-by-user language

While preparing the upcomming "Using Object Oriented Technologies in Secure Systems" tutorial for Ada-Europe (plug, plug...), I came across this beautiful statement (OOTiA, B.1.1.6): "C++ is a strongly typed language, if conversions between logically unrelated types are avoided". Ain't that cute? -- --------------------------------------------------------- J-P. Rosen (rosen@adalog.fr) Visit Adalog's web site at http://www.adalog.fr

X := X; Compiler Warning?

This weekend, I discovered a problem after some effort in debugging. The culprit was something stupid like this: Position_X : Line_Index := ... begin loop .. Position_X := Position_X; -- whoops .. exit when ...; end loop; Obviously, that should have been coded as: Position_X := Position_X + 1; As outlined here, it is trivial to spot. But with the longer variable names (in the original code), I somehow missed it in amongst all of the other statements. Now isn't this something that is normally reported as a warning? I'm using gnat, so

How to exit a loop with keyboard input

[Sorry for the cross-post.] I have a loop which is doing a repetitive calculation. Sometimes the loop runs a long time and I want to manually cause the loop to be exited but have the program continue running, for example to save some results to a file or do other calculations. Preferably I would just hit a key or key combination. I thought Get_Immediate would work (reading Cohen's book) but it does not do what I want. For example, the following program stops looping and requires me to hit RETURN even if I hit another key first. It continues looping (very slowly) if I hold down the

Spark 9 & Ada 2005

Hi Everybody, This problem is intended to people who know Spark. I'm trying to compile the Spark_IO.adb file using -gnat05 option, but there is an error. The error is : spark_io.adb:196:42: (Ada 2005) cannot copy object of a limited type (RM-2005 6.5(5.5/2)) This is a restriction of Ada 2005, and I saw in a message of last year saying that Spark_IO is not compatible with Ada 2005. Is it still the case ? However, the Spark Pro version 9 considers Ada 2005 features. Does anyone know about this problem ? Thanks, Alex

Language lawyer question: access discriminants

I'm hoping someone who understands the rules about access discriminant accessibility level can answer this definitively. This is a reduced example of something I found in someone else's code: package Pack1 is type Rec is record F1 : Integer; end record; type Rec2 (D : access Rec) is limited record F2 : Integer; end record; function Func (Param : Integer) return Rec2; end Pack1; with Pack1; use Pack1; procedure Proc2 is A : access Rec; begin A := Func(1).D; -- LEGAL? end Proc2; I think the statement marked LEGAL? is illegal

global package scope designator?

In C++, a leading "::" before a reference to a namespace denotes the global namespace. There does not seem to be an equivalent for this in Ada. I now ran into a situation where I felt this to be a lack. Here is an example (the original problem involved packages nested three levels deep which I reduced here to two levels for simplicity): -- File: gui.ads package gui is type Obj is new Integer; end gui; -- File: mcc.ads package mcc is end mcc; -- File: mcc-gui.ads package mcc.gui is function F return Natural; end mcc.gui; -- File: mcc-gui.adb with gui; packag

Why is Ada considered "too specialized" for scientific use

I was browsing the net for scientific software written in Ada, and came across this strange statement: http://farside.ph.utexas.edu/teaching/329/lectures/node7.html "Scientific programming languages What is the best high-level language to use for scientific programming? This, unfortunately, is a highly contentious question. Over the years, literally hundreds of high-level languages have been developed. However, few have stood the test of time. Many languages (e.g., Algol, Pascal, Haskell) can be dismissed as ephemeral computer science fads. Others (e.g., Cobol, Lisp, Ada)

ANNOUNCE: Evex 0.50, Evaluation Expression for and in Ada

Evex is a full-featured run-time expression evaluation library providing a variety of built-in mathematical and string manipulation operators and functions. A variable table is maintained for the storage and retrieval of the results of evaluated expressions. New functions can be defined at run-time using the #define built-in function and then subsequently invoked. More complex or application-specific functions, or those requiring higher, natively-compiled performance can be implemented as part of the user's application and then registered as an Evex function.
