One of the weaknesses of Pascal compared to the C language, is a lower number of existing libraries. The reason for that is the much greater popularity of the C language compared to Pascal. Rather than rewrite the existing C libraries in Pascal, an easier alternative is to use the C libraries from Pascal.
This page contains a brief comparison of properties and methods between (trunk version of) Lazarus TAChart package and TeeChart Standard package which comes with Delphi XE2.
This is a list of libraries designed only to work with graphics. If you're looking for a library to be used for game development you should use a game framework or a game engine instead.
We have package "my_pkg" with components TComp1, TComp2 and want to add icons for components to IDE component pallete.
This is a guide on how to build components.
This IDE dialog allows to select a design time package where to add a new component.
With current Lazarus, it is possible to compile and install IDE packages using the lazbuild tool. See lazbuild .
This is an overview of the components included in Lazarus and a comparison to those included with Turbo Delphi (from 2006).
The "components" directory of the Lazarus source tree comes with a number of very useful components, and they are described below. Note that there are also other components which can be downloaded separately from the Lazarus Code and Component Repository .
Lazarus IDE Packages is bundled with IDE and can be installed via main menu: * Package -> Install/Uninstall Packages..
Q: Where do I add the path for source of 3rd party components? In Delphi it was in the "Library path".
In the lNet examples/console/ directory you will find example programs for:
This particular page is about the packages directory in FPC SVN where all non-RTL packages are kept.

Note that starting with 2.2.2, there will be no more packages base and packages extra because all will have been folded into the packages/ subdir. The separation into base and extra was originally because of a simplistic dependancy system (compile base -> fcl -> extra -> fv -> ide), which is no longer needed due to better packaging tools. For the new list see Package List

There are various different meanings of the term "packages" in the combined FPC/Lazarus projects.
FPC is quite a large body of source, and the organisation of the source is a constant problem, with immense effects on release engineering, deployment and packaging. On this page I try to describe some of the problems involved with how FPC is packaged. This is not a constant situation, it evolves as new packages, dependencies and insights are acquired.

* The object is to play a simple WAV sound both in Windows and Linux (Sync and ASync) * There are lots of libraries to do this in a complicated way, but this code should suffice for simple use

A Lazarus package that is intended to be installed needs a Register procedure which declares * all the package components and corresponding files * the tab on which the component s are to be located.
It can be useful to release a FreePascal unit without publishing its source code: * The source code contains proprietary information. * In teaching, because you want to force students to use a unit by its interface (contract) only, and not by looking at its implementation.

TAChart is Lazarus' powerful charting library. It consists of numerous classes and declarations distributed over some 50 units. New users may be overwhelmed by the complexity of usage, and even experienced charters still find gems from time to time.
The work with the Reference Guide has just started and not yet useful.
This article answers frequently asked questions related to usage of TAChart at runtime.
This tutorial shows how to create a chart with multiple series in their own panes and with their own left axes and one common bottom axis. It was created while checking out the nice "Panes demo" which you can find in the folder components/tachart/demo/panes of your Lazarus installation. Since a second topic is included in this sample project it may be a bit difficult to catch the basic idea. So here we explain how you can do this from scratch.
Several libraries are available for embedding video playback within Lazarus applications. These range from simple to complex.
