I wasn't thrown out of heaven for nothing. :) And please forgive me for not living in the past. OpenGL accelerated desktops far beyond what compiz/aero/etc can do are the future. And I am not getting tired of promoting OpenGL. FPC works with OpenGL very nicely and can deliver high quality and high performance graphics as good as any C/C++ application. We just need to show this to the masses. You win people with eye-candy as Ubuntu has shown.

Special FX like particle systems, shots, etc. If you want to see what difference hw acceleration makes, take a look at chromium B.S.U.

They are developed for doing nicer and faster graphics than CPU based rendering can achieve. If it is 2D or 3D doesn't matter, your gfx card can do it faster than the CPU and you have your CPU left for gamelogic and other stuff. And GPUs are standard in nowadays computers, so why not use them?

Sounds good, only that the CPU instead of the GPU is doing the graphics work is so old school.

Sounds like you put some serious work into your gamepack, but I don't think that something as specialised as this should be a standard component. Remember that it is only usefull for 2D games on old hardware as you can get all of this (and some nice features more) by using OpenGL for your rendering. All your gamepack can do can be done hardware accelerated on any card that supports OpenGL 1.1 (this means really, really old gfx cards and most newer integrated gfx chips, too). But I have some questions regarding it nonetheless. How do you handle sound, input (keys/mouse/gamepad/etc) and what timing method do you use? How many sprites can be used simultaneously with interactive framerates (30 fps or more)? Do your sprites support rotation and/or scaling? Do your sprites support transparency and blending?

If you are one of them I would be really interested to know what math libraries you use to achieve the best performance you can get.

Looks like we have different definitions of hw acceleration.

SDL is no acceleration, only if you use its OpenGL wrapper functionality you get hw acceleration.

I would if I could. But I launch my progs through 'run_and_wait' (or some such) and that does not work with gdb AFAIK.

Nope, but I don't use a debugger in lazarus.
I just tried again and loading a png works, but loading a bmp fails. At least I
managed to produce a hopefully more meaningful backtrace:

Hopefully not, but as stated it worked before. And 'hand created' images work
AFAICT without problems. Only the file loading code is broken.

If I only knew. I am just loading 6 or 7 pics (some bmp, and a png). Perhaps it
is not an endless loop but it at least spams the terminal with the above shown
output and throws exception message dialogs until I kill it.

The error is an 'invalid type cast'.

[lazarus] My image loading is broken
Hi,
as the subject says. I just realized that it does not work anymore (after
working flawlessly for years). The latest svn revision that works for me is
11800. Perhaps there are later revisions that work but some I could not compile
and others did not start and I got tired of just randomly trying revision
numbers and compile lazarus over and over. To me this looks like Marcs new
image code is responsible for my troubles.
Btw I am using a TFPCustomImage descendant and the ImagesForLazarus package.

I cannot get it to work. I always get an AV on LoadCursorFromLazarusResource.
Is there anything special about the .ico file I have to create? I tried it with
a 1x1 pixel file created with the Gimp and saved as .ico. Then using lazres to
create a .lrs.
I tried it again with mouse.ico from the lazarus/images directory, again an AV.
I am sure that I am doing something wrong, but I don't know what.

For application developers point > of view, there shouldn't be little workarounds depending on the > widgetset used. If all widgetsets would work the same that would be true. But things are as always more complicated. Linux, Mac OS and Windows all use different design philosophies for their GUIs. The users of the corresponding OS want their apps to look and feel 'native'. But to achieve a native look&feel you have to adhere to the design standards of the given platform. You just cannot easily abstract everything without loosing those differences. As lazarus is developed by a rather small team it is mostly not worth the effort to make such little details work as that can be complex tasks with little benefit. People coming from Delphi sometimes seem to forget that for Delphi most things are much more easy as it is only single platform and Borland/Inprise/whatever-they-are-called-nowadays had enough trouble getting Kylix to work (and failed) and that is just one other platform. If you need more 'exotic' features of the GUI it is the task of the developer to make sure that they work (more or less) consistent on every platform. And then the developer has to know a little bit more about the widgetsets than a developer that only needs 'standard' functionality. If there were open standards for gui toolkits there would be no problem but there aren't any and so sometimes a multi-platform developer has to know a bit or two about the platforms he develops for and has to include platform specific code. Don't get me wrong. I really would like to just write code once and it works on every platform the same and for many things lazarus achieves this but unfortunately not for all. And this is not just a problem with widgetsets. I code mostly OpenGL which was developed as a cross platform library and even I don't get around using platform specific code for some tasks. So in conclusion some things that are high on your priority list are low on the priority list of the lazarus developers and I hope I could explain why although I am not a lazarus developer. Btw I don't give a for VCL/Delphi compatability but unfortunately the developers have a different opinion. So we both have to live with what we get. You can at least hope and help that your feature requests get included in lazarus. But I don't thinks that lazarus will drop Delphi compatability anytime soon, well, perhaps when hell freezes over.

Following your reasoning every widgetset on *nix is custom drawn. Sorry, but you have no point at all. On *nix the desktop enviroment determines what's native. *nix system are different in that respect as the widgetsets are not tied to the OS like on Mac or Win.

Of course it is easy as it looks as ugly as my GTK Lazarus (for some unknown reason I cannot use GTK pixmap themes). Is there theme support planed? It will be really hard to get Mac OS X users to use apps that look like this. They want that all their apps look the same and that is true for me, too, but I am a gfx guy so I like nice looks more than other people. _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Take a look at any other Music/Video-Player. They all started out trying to mimic some kind of HiFi/Video equipment and users want them to look fancy. Why do you think are there millions of mplayer or xine skins? Same for xmms. That's all because they are Media-Apps and used by Joe Sixpack all day long (the same reason why every crappy shareware app comes with it's own skin). So the Mediaplayer is by far the worst example for an application that does not use the native widget set. Are there any serious apps using the WMP widgetset? No? Thought so. I can see that for your purpose a non native widget set may be The Best Thing(tm). But for Lazarus as a whole the current practice of using native widgetsets is IMHO much better. Being able to achieve a native look and feel on the supported plattforms is just great. If the user has the choice between native and non native most will choose the native one. The same reason why KDE-guys use mostly QT apps and Gnome ones use mostly GTK apps. Btw are there any screenshots or even better a working example of fpGUI in action?

Perhaps, if you don't need any images and yes, icons and most gtk themes do count as images. So I don't think there is a way. At least if you use gtk.

[lazarus] Lazarus crashes on errors in form
When I compile a unit with a form in it which contains errors Lazarus crashes.
It correctly stops and shows the errors if the unit in question does not
contain a form.
In my test cases this was always the main form and I did not try it with other
forms.
Here is the output of lazarus:

glslform.pp(319,43) Error: Illegal expression

[lazarus] Debugger problems without debugger
Hi everyone, I run my projects inside the IDE through the run and wait script. After closing my running program the IDE 'stays in the debugging session' as shown by '(debugging)' in the caption of the lazarus editor. I cannot stop the debugger and have to reset it to get back to the normal state. This is all without having specified any debugger at all. This is really annoying and any help is highly welcome.

[lazarus] OT: fast vector and matrix math
Hello everyone, I know this is probably the wrong list to ask such thing but as I am not on the fpc list and many people on this list know alot more about coding than I do I just ask here. I exclusively do (real time) graphics programming (on a hobby level) and for most stuff freepascal is fast enough. But now I have come to a point where I'd really like to have some faster vector/matrix math. So I ask you guys if anybody knows of a way to achieve this. I have read that SSE/3DNow are the way to go but AFAIK there is no support for that in fpc. I don't know much about interaction with other languages but would it be possible to use/write a SSE/3DNow math lib in C and then use this for my calculations. (I hate C but more speed is more speed and if it is only the real low level stuff, I think I can deal with it). I am open for any suggestion esp. the ones not involving any C coding. thanks for any help Satan _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

I was just asking because I am on a long journey to find good cross plattform (I am on Linux) OpenGL headers for fpc as the ones that come with fpc are not 'good enough' for me and at the moment I am using some selfmade ones that are not great but do the job under Linux and OSX.

Re: [lazarus] Running a project always performs compile and link sequence
After reading this thread I ask myself what is wrong with always compiling and linking the project? I can speak only for myself but most of the time I invoke 'run' I want my project to be rebuild since I know something changed (I am inside an IDE and doing some coding, after all). If I know that nothing changed and I just want to run the last compiled binary my terminal is just a short-cut away so no problems there. If it is such a great problem to start your program from somewhere else then there could be an option like 'run last compiled binary' and Lazarus just runs that with the developer deciding if something changed (he should know). All in all I just do not see the benefits in Lazarus knowing if it has to compile and link the project or not, especially if it is that hard to get the needed information. Perhaps someone can enlighten me and tell me the benefits. satan _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

It is not much trouble if you use a package manager which knows and installs all dependencies for a given package. As it looks like you are either using Mandrake or Mandriva Linux.

As I said above it is not much trouble if you have the right tools at hand and I am sure Mandriva provides a way to install packages and automatically solve the dependencies.

Remember OpenGL is slow in line and point drawing on consumer level hardware, OpenGL is slow if running in software (at least at our university we don't have computers with 3D cards attached to our measuring equipment, many are running dos :) ). And you need a little understanding of how OpenGL works (perhaps GLScene takes away this requirement, I never tried it) meaning that with canvas drawing you work on pixels (which is quite intuitive for most programmers) while OpenGL as a vector graphics API takes an other approach and for someone not familiar with the inner workings of OpenGL it might not be as intuitive as canvas drawing. I think standard canvas drawing should be fast enough and since lazarus is cross plattform it is cross plattform, too, and really easy to use. If for any reason canvas drawing is really too slow OpenGL is of course the alternative. just my 2 cent _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

> Maybe someone has an idea? > The problem seems to be the use of gtk1 pixmap themes as lazarus always crashes while using one of these. Using themes that do not rely on the gtk pixmap engine solves the problem. The downside is that all good looking themes I know are pixmap based but at least lazarus works again. _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

> Btw the only changes to my system I can think of were some security updates, > mostly xorg but I cannot see any connection. After a lot of trouble I have verified that the xorg security update is the reason for lazarus stopping to work. I downgraded the xserver and all its dependencies manually and now lazarus starts again. For the time being I can keep the old version of xorg but I think this is a real problem as I like to keep my system updated in regard to security issues. These are the details about the vulnerability from the Ubuntu security notes: A local privilege escalation vulnerability has been discovered in the pixmap allocation handling of the X server. By allocating a huge pixmap, a local user could trigger an integer overflow that resulted in a memory allocation that was too small for the requested pixmap. This resulted in a buffer overflow which could eventually be exploited to execute arbitrary code with full root privileges. _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
[lazarus] Lazarus crashes while starting
Hi everyone, I am in need of a little help. Yesterday I did a svn update and all worked perfectly. Today I wanted to work a little on my project but lazarus crashed. I did an svn update tried it again and lazarus told me that there was a problem opening my project the last time I tried to start lazarus and asked me if I wanted to load my project anyway. Neither anwsering yes nor no changed anything about the crash. Here is the output of lazarus (being told not to load my project) and my try to get a backtrace which failed (I don't know why): [EMAIL PROTECTED]:~/pascal/lazarus$ gdb lazarus GNU gdb 6.3-debian Copyright 2004 Free Software Foundation, Inc.

I am using Ubuntu myself but I installed GTK1 and never tried to build Lazarus with GTK2 support so I cannot help you there. As far as I can see libglib2.0-dev is in the standard Ubuntu repository, you should be able to just 'apt-get install' it or you can use synaptic. To your last question I don't know if you should use Redhat or not but Ubuntu is not missing the development packages it just does not install them as many people don't need them. You may install all the dev-packages you need via apt-get/synaptic. hope this helps a little _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
