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 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.

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

ExtDesigner, ExtJS, ExtDirect Demo

Need the help of someone who is familiar with ExtJS to create a demo along this line that does the following:

1. Login session (users/passwords/emails will be stored in text file).

2. On successful login, show a form with 2 tabs: a). First tab displays user grid (username, password, email), delete record, edit record, add record. Changes will be made to user text file. Similarly, changes made to the user test file will be automatically updated on the grid. b). Second tab displays a checkbox, a textfield, a date/timefield, and a pair of radio buttons, with values taken from an .ini file. Users can edit the fields, submit changes and cancel changes. On submit changes, commit changes to .ini file. Similarly, changes made to the .ini file will be automatically updated on the tab.

3. Logout session.

Code should be commented for me (a novice) to understand. Frontend GUI should be created using ExtDesigner and you need to screen record to show how you create the GUI using ExtDesigner and link it to the backend FPC using ExtDirect.

Code will be open source and can be attributed to the author. Bounty: US$150. Pay by Paypal. Contact: joshualimming at gmail dot com


System wide hotkey

Hook keyboard on Linux/OSX US $20/Paypal Source would be donated to FreePascal as there is nothing there yet. Contact: alistair.3ns at gishpuppy dot com


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 Solved by Mattias.

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...

Click to see Blinn-Phong shading Figure 5.5

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

GLScene improvements

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

  http://www.melax.com/polychop
  http://www.jsomers.com/vipm_demo/meshsimp.html

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

Windows bounties

Windows 8 64bit Pro (Full/Upgrade)

I'm looking to better Lazarus on Windows 8 (64bit). I realize it just came out and it may be not worth the time to run (even in a virtual-box).

I'm offering a few serious Lazarus core developers a copy of windows 8 so they can have it to run and test and improve Lazarus.

The only thing I want is

 1: fcl-db components present (currently missing postgresql).
 2: Install path with space like "Program Files" and be able to Build Projects.  
    If the problem is out of scope - clearly identify problem areas and their
    external projects.

Email me for acceptance, I will buy and drop-ship you the cd. You retain license for your time. Win8 Pro Upgrade or Win8 Pro Full.

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).

Light bulb  Note: The bounty has been assigned to Paul Ishenin and has been completely implemented. It is now up to me and the users of this open source project to verify if everything is working as expected.

Gtk bounties

Fix bug - $10

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

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

Making paszlib zipper Mac/Unix compatible

Tom G. earned 100 EUR for making the paszlib zipper Mac/Unix compatible. The zipper in paszlib(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)

bug 15768

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.
