HI Reinier, Many thanks for that Tutorial. I was going to look for something similar today. It answers most of my possible questions about developing dbf's in Lazarus.

Re: [Lazarus] New member with compiler query
I believe that we can close this thread. Have been working with Lazarus over the past few days and find that much of my memories from Turbo Pascal and Delphi are still very relevant. The Topaz database modules have been abandoned, certainly they had some shortcuts, such as a built in Label for Edit boxes. A couple of compiled test programs are working well on Puppy Linux but the Ubuntu variants ask for a program to open the files. I believed that these programs were free-standing and ready to run. Obviously I have more reading to do. Gordon Tauranga N.Z. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] New member with compiler query
Reiner, The Topaz database modules were all based on the dbf system with three separate files, a linked list .dbf containing Titles and Headings that effectively controlled the saved data, .dbt containing the data items themselves, and .mdx a multiple indexing system. I originally wrote a small program for members of an on-line craft group to save hints and tips exchanged by email, but it developed into a larger project with one fairly complex database looking after the diet and feeding arrangements for a large number of animals in a zoo. Now, I am thinking about using dbf again but am still getting to grips with the data saving options in Lazarus/Free Pascal. Progress so far (two days) has been limited to writing brief test programs, getting syntax correct etc. Now I am trying to resolve a portability problem. My compiled fP file runs immediately and perfectly on Puppy Linux but will not run on Kubuntu or Mepis. Both these systems are asking me to select a program to run the file. This may be a permissions issue, although all appears to be correct. Gordon.

Re: [Lazarus] New member with compiler query
It was a Linux permissions issue, and has been fixed. I found that a Free Pascal executable file would not be executable if being read from USB memory stick. Puppy Linux is automatically in the Root option and so ignores the lack of a permission. Gordon.

Are you sure you mean Motorola CPUs? For clarification: there are two completely different versions if the Mac operating system: MacOS (also called MacOS Classic here) and MacOS X (simply MacOS here). The former ran on m68k and later Power CPUs while the later ran/runs on Power (up until 10.4 or so) and Intel CPUs. Considering that the Classic m68k version is *very* old I don't think that you'll need to support that. I suspect the lowest you'll get is MacOS X on Power. And that (and the Intel version of course) is supported by Lazarus and Free Pascal. In theory FPC also supports MacOS classic for Power, but that is rather likely not in operational state as it wasn't tested for a long time. Additionally there would be no Lazarus support. And since FPC's m68k port was revived we could in theory also support the very old Macs, but noone has tried that yet.

Forget the 68k-based Macs, they're for retro buffs (yes, I've got one). If you can lay hands on a PowerPC (PPC) Mac with OSX then it might be relevant, you might be able to dual-boot it to Linux but don't expect mainstream distreaux to keep up with x86 (I've had to stop at Lenny on one of mine). Otherwise I think you need to keep your eyes open for an Intel-based Mac, I'm not sure that you'd be able to run OSX on a standard PC even if you could get hold of a copy. I've not yet got FPC/Lazarus running on my OSX PPC Mac. I believe it does, but there's quite simply limits to how many things I can do with limited time. But in general, Lazarus on different unix platforms and in particular on different Linux distreaux is pretty consistent: the last mile is going to be compiling for OSX, and trying to conform to Apple's design guidelines and the Apple community's expectations. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] New member with compiler query
Thanks for the welcome. Have just joined the list. Background, worked with Pascal on an old IBM mainframe, input by punched cards. The used Turbo Pascal from Version 2, Delphi up to Vsn 3 with Topaz modules for small freestanding databases. Then I moved to Linux and database work ceased. Looked at Free Pascal a few years ago but did not go further. Now have Lazarus on Kubuntu 12.04 and am attempting to load it on to the new MX-14 lightweight OS. Have glanced at the list archives and see there is a lot of reading to do. My query : With the demise of WinXP, I've have been asked to look at converting some of my old Delphi programs (written for MS machines), so that they will run on Macs. Does this mean that I would have to compile any freePascal rewrites on a Mackintosh computer?

Re: [Lazarus] New member with compiler query
Does this mean that I would have to compile any freePascal rewrites on a Mackintosh computer? You can cross compile from Linux as well, but you will still need some Mac tools. See the cross compiling wiki article. But surely it's much easier to build on Mac directly. See all Delphi porting wiki and documentation articles, the conversion might not be straightforward. -- View this message in context: http://free-pascal-lazarus.989080.n3.nabble.com/Lazarus-New-member-with-compiler-query-tp4036844p4036845.html Sent from the Free Pascal - Lazarus mailing list archive at Nabble.com. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Agree that the conversion may have problems, so am prepared to do a complete rewrite if needed. Still have get my head around the Delphi/fP differences.
