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.
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 .
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:

* 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.
