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 no one interested in your bounty, it's probably because the price is too low. Also, try to keep all bounties above 50 dollars. 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.
- Make Lazarus hello world work on PamOS 5 Garnet. $1000 Contact firstname.lastname@example.org
- Implement a new feature. Please make a budget Contact email@example.com
Cross-Compile to Android on Ubuntu X64
I would like to be able to build Android apps using Lazarus/Object Pascal on Ubuntu X64.

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 [How to donate to Lazarus|Lazarus paypal account].
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 Solved by Mattias.
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
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_gatech(dot)edu $300
I am looking for a GLScene implementation that can reduce the triangle count of a GLFreeForm mesh. In other words, I want to remove the vertices/triangles that do not substantially improve the image. Here are two source plus executatable implementations for C++, but it is not clear how to implement this elegantly with Pascal
I think a solution would be generally useful to many GLScene users, and I would personally offer a $50 USD bounty to the first person who can provide me with a solution. The GLScene MeshSource demo might be a good example, as it starts with a cube composed of 300 triangles (whereas it could be decimated to 12 losslessly). Contact rorden_AT_gatech(dot)edu
SQL Database Administration Components $500 US
FPC/Lazarus needs a cross platform TSQLConnector based component for Create & Drop Databases, Add Table Drop Table and Alter Table. The solution to this bounty will be complete when a base TSQLAdministration component is developed to manage fields, tables, and database. Fields and their types must be enforced. TSQLAdministration extensions for native MySQL, PostgreSQL, and OracleSQL must also be supported.
The Base class and Three extended classes must be packaged and included in Lazarus distribution for optional installation in the IDE pallet.
The individual or point of contact for a group will receive $500.00 ($US). Contact Andrew Brunner (firstname.lastname@example.org) to register. A work in progress should be submitted to appropriate FPC/Lazarus SVN.
LAZARUS RUNING IN A LINUX MACHINE COMPILING TO ARM/LINUX $500 US ==
I need help to install Lazarus, FPC and other files to compile a "HELLO WORLD" binarie to Arm/Linux hardware. Contact Anderson Magalhaes (email@example.com). (If you are in Brazil we can pay flight tickets and other needs)
Fixing bug #7182 - $100
$100 for fixing bug #7182 (http://bugs.freepascal.org/view.php?id=7182). Contact oleg_3630 at mail.ru.
Reparent Forms (100€)
Related to the bounty above, I'd like to spend another 100€ (see bounty above) for anyone who manages to reparent a form with a specified owner (data module) to a given parent window handle (HWnd). In Delphi this is pretty simple (ParentWindow := NewParentWindowHandle), but it is not working properly in Lazarus. The form should be reparented completely (incl. accepting keyboard/mouse input and such). The solution should work on several platforms (i.e. no direct call to the WinAPI or such, this should be handled by the LCL) The code will be used for my open source project "Delphi ASIO & VST Packages" to make them usable with Lazarus (planned for version 1.5). Please contact me prior to fixing this (Christian at savioursofsoul.de)
Fix bug - $10
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 firstname.lastname@example.org
Windows CE bounties
None Bold text
RTL for Symbian phones - $1000
Create an RTL for Symbian phones (FPC for ARM already exists).
- Include a very simple GUI app (like this one for PocketPC).
- Needed for Symbian UIQ 2 and 3 at least.
- Bounty $1000, open for negotiation if Series 60/80/90 supported.
- Contact bounty (at) ccrdu.de.
These are examples of successfully concluded bounties.
GTK2 clipping rect error
Paul Ishenin earned $50 for fixing a bug with GTK2 (Clipping rect of newly created bitmap was invalid). He then donated these funds to the Lazarus PayPal account. http://bugs.freepascal.org/view.php?id=12026
Small Fix for Linux x86_64 IDE
- Vincent earned $50 US for discovering why Linux x86_64 caused the IDE to report an Access Violation when opening the MRIcron project. This bug was also reported on Mantis (http://www.freepascal.org/mantis/view.php?id=9216).
- Tombo earned $600 US for developing new Carbon components including TSpinEdit, TFloatSpinEdit, TSpeedButton
- Tombo earned $50.00 US for extending LazRGBGraphics to support the QT widgetset - offered by rorden at gwm.sc.edu
Small Windows Bugs
- Jesús earned $40 US for fixing a bug where copying images with the edit/copy caused all pixels with the color shown in the bottom-left corner to appear black (http://www.sph.sc.edu/comd/rorden/mricron/bounty/)
Apache modules - €300
- Apache modules header translation and basic example. Awarded to Sekelsenmat.
Making paszlib zipper Mac/Unix compatible
Tom G. earned 100 EUR for making the paszlib zipper Mac/Unix compatible. The zipper (TUnZipper.UnzipAllFiles) had no support for symbolic links, did not set executable bits of unzipped executable files, did not support directories, and raised a CRC exception. Thanks Tom for fixing this! - offered by Grau GbR (www.grauonline.de)
Make TListView "Virtual"
Dmitry B. (aka skalogryz) earned 200 EUR for making the Win32 and Carbon TListView implementations "virtual" - before that, TListView was not 100% Delphi compatible - the ability to set OwnerData=true together with an OnData Event-Handler was missing (http://bugs.freepascal.org/view.php?id=7749). Thanks Dmitry for fixing this! - offered by Grau GbR (www.grauonline.de)
Paul Ishenin earned $300 for fixing an access violation produced when raising an exception (any exception) in a safecall method for the x64 compiler (bug 15768). Bounty was offered by Dmitry Streblechenko.
Creation and support of grammar FPC in notation EBNF in meta-language GOLD Meta-Language ( http://www.devincook.com/goldparser/grammars/index.htm ). The grammar should include all opportunities of language: interfaces, comments, instructions of the compiler, all announcements, keywords, etc. >1000$. Contact email@example.com
