Strange though... If you read all of his messages: He had the problems with: Lazarus 0.9.30.2-2 on XUbuntu 12.04-1 running KDE 4. He then said, he tried the current deb from sourceforge, and it solved it for him. Marc Hanisch also said that the upgrade did him good. You have the problem with 1.0.x and you are fine with 0.9.30,2 (you reverted to that) So apparently something was fixed, and something else broken I've got problems with 1.0.4 on SPARC Linux which is probably something to do with alignment although there's an outside chance that it could be due to the computer having more CPUs than most- it's been little-used for several years so I've not been testing FPC/Lazarus on it regularly. http://bugs.freepascal.org/view.php?id=23703 Timothy, Graeme: I stress that I'm not seeing the sort of gross unreliability that you report, and I've probably run most (even-numbered) versions since around 0.9.24. If you've got specific problems then please raise them for discussion and if necessary bug-report them. From a support POV, I'm bothered that there's something unpleasant lurking: number or speed of CPUs, type of graphics card, amount or type of memory (testable on x86 using a MemTest CD). My usual OS-of-choice, irrespective of CPU, is Debian+KDE. In some cases this is KDE3, in others KDE4; in most cases I run headless. I usually run the IDE with GTK rather than Qt, although where possible I try to build for Qt on occasion.

But if I am, then case sensitivity should be part of any sort/comparison, at least as an option. I have had many problems when it is not. aA-Bb-Cc-dD is a form of randomness. If the result of a sort can not be reliably reproduced after adding new data, the sort fails. Case sensitive sort is common. Take a look at almost any spreadsheet program and you will see that it is an option. It's also an option in TStringList. In my opinion Case Sensitive should be the default behavior of any Sort/Comparison. A case statement IMO should not rely on sort/compare options, unless there exists a syntax extension for such specifications. It also should be insensitive to string encodings (codepages). If you want to be sure of the results, you replace the case statement by a chain of explicit comparisons, using the desired string comparison functions.

Looking at Mantis, it looks as though you've reported bugs against nothing more recent than 0.9.30 and all of them were handled adequately: either resolved or closed after you didn't supply more info. Looking at something that I reported, there were changes in the IDE post 0.9.30 that affected form display under some particularly contrived conditions (roughly translated: there was a better way to do something than I knew about). The particular one that I reported was fixed and I believe is now in 1.0.2, but there's always a possibility that there are related problems still in there. Also some bugs are very hard to report because I can't reproduce all of them on demand. And as a developer, I know that getting a bug report that you can't reproduce is a big turn-down. And speaking as somebody who's done a lot of support over the years, I know that the worst thing is somebody who refuses to be helped. And it's even worse when they're arrogant with it.

[Lazarus] GTK2 threading
Dear Lazarus developers! I'm examining the problem disturbing me for years. GTK2 applications provide thread-safety using internal mutexes passed through gdk_thread_init() And it works. Pure X-Applcation does so (orders X-messages per-thread) using XInitThreads at early start of application. And it also works But GTK Widgetset uses pure Xlib calls for determining keyboard states. Xlib thread-safety is not initialized in GTK2 widgetset. IMO the problem half-way to resolve - either not use Xlib calls (pure GTK2,3 - it is threadsafe) or make GTK and Xlib interoperable. Or block GTK calls until Xlib call returned. with best regards, Anton -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

It's not really a problem, I just want to know the reason why this value was chosen. Before my patch on http://bugs.freepascal.org/view.php?id=22170 the depth bits were hardcoded (16 on WinAPI and 1 on GLX). So I set the default value for TOpenGLControl.DepthBits at safe 16. The general idea is that TOpenGLControl has safe default values, that are guaranteed to work (and be fast) even on really really ancient graphic cards or when the system is running under virtual machine (which often means you don't get hardware-accelarated 3D until you explicitly install/enable something). For the same reason e.g. TOpenGLControl.StencilBits is by default 0, even though all modern GPUs can give you at least 8-bit stencil buffer. Other APIs to get OpenGL context, like GtkGLExt or Glut or low-level WinAPI or GLX follow the same convention. The defaults are very conservative. That said, I would be personally fine with changing this default to 24, if others think it's a good idea. A developer can always lower it to 16 when that's enough. So, I don't really have a strong preference about it. Michalis -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] Dynamic library dependency error
Thanks, I added -fPIC and it worked, it seems no need to add -dFPC_PIC? Also I found a small problem. While create a new shared library and compile fpc always complain that -WR is invalid. I have to uncheck Relocatable option to fix this. I think this is a bug in lazarus project template, what do you think? 2013/1/23 Antonio Fortuny a.fort...@sitasoftware.lu Le 22/01/2013 16:14, xrfang a écrit : Hi Howard, Thanks for your info.  After adding LCLBase to dependencies, I get these errors: /usr/bin/ld: warning: link.res contains output sections; did you forget -T? /usr/bin/ld: /home/xrfang/Desktop/**paintrect/lib/x86_64-linux/**paintrect.o: relocation R_X86_64_32S against `_$PAINTRECT$_Ld1' can not be used when making a shared object; recompile with -fPIC /home/xrfang/Desktop/**paintrect/lib/x86_64-linux/**paintrect.o: æ— æ³•è¯»å –ç¬¦å ·: 错误的值 liboval.lpr(14) Error: Error while linking where æ— æ³•è¯»å –ç¬¦å ·: 错误的值 means cannot read symbol: illegal value.
