ADA

Ada downsizing in space
It was very pleasant reading the recent thread about "Ada is popular after all" but local events make me think other wise. I have to believe that the International Space Station (ISS) was one of the biggest Ada projects in the world, employing people in several nations writing Ada. NASA has decreed that there... 20 Feb 2007 11:10

Problems installing gnade
Hi, I'm trying to install gnade 1.5.3b on a Gentoo Linux system with gnat 4..1.2, postgresql 8.1.8, sqlite 3.3.12 and unixODBC 2.2.11. When I run ./configure --sampledb=postgres --no-odbc sqlite postgres (also tried without --no-odbc), I get the following output: GNAT Data Base Developement Environment (GN... 17 Feb 2007 13:50

Behaviour of Version attribute
I've been exploring the Version attribute and finding some behaviour I didn't expect with GNAT (GPL 2006 and earlier versions). It seems that GNAT only considers top-level library packages. Given package Version is end Version; procedure Version.Impl; with Ada.Text_IO; use Ada.Text_IO; procedur... 17 Feb 2007 12:48

Ada.Containers.Doubly_Linked_Lists
Okay, got the packages "instantiated" and all that and successfully appended an "element" to my list. How do I print the length to the console? Where is count_type defined? a wiki link would suffice so long as it has an example of how to use the mysterious count_type. Andrew ... 7 Feb 2007 02:53

Ada is popular after all
Remember my tirade [1] about how some languages are the "zen masters" of programming? I quickly looked at the results of Debian's Popularity Contest [2], which ranks packages in Debian according to their popularity. (This ranking helps choose which CD-ROM or DVD-ROM each package ships on. There are currently 23 CD-... 7 Feb 2007 10:54

Ada.Containers.Doubly_Linked_Lists
Ahhhhh, I see. Okay, so, just out of curiosity, what do I do if I need the Node_type within Ada.Containers.Doubly_Linked_Lists to have an additional "attribute"? So instead of just having type Node_Type is limited record Element : Element_Access; Next : Node_Access; Prev : Node_Access; end record; ... 5 Feb 2007 11:15

C Interface example
Hi. I'm having a bit of trouble getting my head around calling C code in Ada. I'll spare you my failed attempts, basically I have this code: (vector.h) #ifndef VECTOR_H #define VECTOR_H float *vec_addNf(float *, float *, unsigned int); #endif (vec_add.c) #include "vector.h" float *vec_add(floa... 6 Feb 2007 03:41
