Introduction

Need a particular feature? Set a price here, giving a short description, your name and email address. Hopefully, one or more people will contact you and you can arrange the terms of this development work.

Currently, Lazarus depends on volunteers to implement everything on it. Recently Lazarus popularity has increased a lot, and many commercial projects are being developed with it. The idea behind the Bounties is not to substitute the current Mantis bug system, where work will continue normally. The idea is to provide a new development mechanism where commercial application developers can receive professional support and at the same time be able to contribute back to the community.

If there is noone interrested in your bounty, it's probably because the price is too low. Also, try to keep all bounties above 50 dolars. Bellow that it usually won't be worth the time investigating the problem. Please also date your bounties. This way at some point we can weed out really old ones.

Examples:

  • Make Lazarus hello world work on PamOS 5 Garnet. $1000 Contact myemail@domain.com
  • Implement a new feature. Please make a budget Contact myemail@domain.com

Multi-platform bounties

FPC grammar

Creation and support of grammar FPC in notation EBNF in meta-language GOLD Meta-Language ( http://www.devincook.com/goldparser/grammars/index.htm ). The grammar should include all opportunities of language: interfaces, comments, instructions of the compiler, all announcements, keywords, etc. >1000$. Contact xayam@yandex.ru

Optimizations for FPC/Lazarus

Two bounties, totally $100 for speed optimizations for FPC/Lazarus are described on my web page http://www.sph.sc.edu/comd/rorden/mricron/bounty/. Martin Friebe won one of these (for changing the code, not the compiler) and donated the $50 to the Lazarus paypal account.

IDE Enhancements

1.) If a path is added in the Compiler-Options of a project then add the path as a relative path instead of an absolute path. $20

2.) If in the MessageView the sentence "Can't find unit XYZ" is displayed, it should be possible to doubleclick onto the word "XYZ" and this would open the "FindInFiles" dialog. $20

GLScene improvements

The GLScene Texture3D demo (Lazarus version at http://www.mricro.com/texture3d.zip) currently generates volume rendering. I want to encourage someone to add the ability to add surface shading. The picture at http://www.mricro.com/rendert.jpg shows a sample image with pure volume rendering (left), pure surface shading (middle) and a mixture. I would like to achieve this using the GPU. A compiled program with C++ source code and sample image is available at

 http://www.real-time-volume-graphics.org/?page_id=5

To see the effect, download the 3D Texture Slicer and launch the SimpleSlicer.exe. At first the program displays a volume rendering, but press the 'm' key to switch the mode to surface shading. The book associated with this C++ code describes the implementation: Listing 5.6 for computing on-the-fly-gradients and Listing 5.1 for the Blinn-Phong shading. See Figure 5.5 for example output...

Bounty will be paid to the first person who can send me GPU-accelerated shading for the Texture3D demo, or my open source MRIcroGL (http://www.mricro.com/mricrogl). Contact rorden_AT_gwm(dot)sc(dot)edu $300

Windows bounties

Fixing bug #7182 - $100

$100 for fixing bug #7182 (http://bugs.freepascal.org/view.php?id=7182). Contact oleg_3630 at mail.ru.

Make TListView "Virtual"

In current Win32, Carbon and GTK implementations, the TListView is not 100% Delphi compatible - the ability to set OwnerData=true together with an OnData Event-Handler is missing (http://bugs.freepascal.org/view.php?id=7749) - 100 EUR for adding this to the Windows port - Contact us

Gtk bounties

Fix bug - $10

http://mantis.freepascal.org/view.php?id=11906 Contact http://www.wordwebsoftware.com/contact.html


Fix bugs on Gtk 2 IDE and Interface - $200

  • $200.00 US to anyone or group that gets the IDE to use gtk2 and to compile programs for GTK2 without major GUI bugs - both should work. The award of the bounty will be determined by votes from the mailing list. The list will first vote if the IDE and programs work and then on which person or group should receive the bounty.

Fix GLScene volume rendering on Linux

  • $100.00 US for anyone who can get GLScene's volume rendering working on Linux. I have adapted Jürgen Abel's Texture3D glscene demo (http://glscene.sourceforge.net/wikka/UserDemos/) to compile under either Delphi or Lazarus. My new code is here www.mricro.com/texture3d.zip. The Lazarus code (0.9.26.2, using SVN snapshot of GLScene) works fine under Windows and OSX, but when I compile it with Linux the volume is always rendered as an opaque white cube. I get the same results with Fedora10 using ATI 4850 and Ubuntu 9.04 using a NVidia GTX9800. Both computers are set up with the recommended proprietary. Contact rorden@mailbox.sc.edu

Windows CE bounties
