Q: I installed a package, but the IDE does not find the unitsĪ: Installing a package means that the package is integrated into the IDE, not in your project. Use the project inspector and add a requirement.

If you only want to use a package in your project, don't install it. If you don't use those items, you don't need to install the package. Use packages instead.Ī: You only need to install a package, if it contains designtime items, like components for the IDE component palette. That's why this is not supported by Lazarus. This has many drawbacks when sharing code. If a unit can not be found, under Delphi you are used to add the directory to the global search path.Lazarus will automatically load the right version. Lazarus packages have version information and projects can define that they require at least or at most a specific version of a package. But you can do that for Delphi compatibility.

Many Delphi packages provide one 'package project' per compiler version.

Sometimes the Delphi main file of a package is called 'Package Project'.

They are used to share units between projects and modularize big projects. Lazarus packages are not only a dynamic library.If you are familiar with Delphi packages then read the following paragraph, because there are some important differences between a Delphi and a Lazarus package. piled - the state file containing the parameters how the package was compiled the last time. The directory and its content is automatically created. Lib/i386-linux/ - the output directory of the package. Pkg1.pas - this unit is automatically created by the IDE and is only needed for compilingĪpackageunit.pas - your shared unit, choose a unique name that do not clash with other sources/packagesĪform.lfm - the form file of your shared form home/user/pascal/pkg1/ - an arbitrary directory, often it is named similar to the package name Here is a typical directory layout of a Lazarus package:

Packages are ideal for sharing code between projects. Therefore you must compile and restart the IDE, each time a package is installed or uninstalled.Ī lazarus package is identified/distinguished by the name and its version. Delphi/Library packages require in-compiler support, which FPC is not capable of at the moment and of course this magic is OS dependent.)Ĭurrently the Free Pascal compiler only supports static packages, not dynamic packages. ( Library Packages are specially compiled libraries used by applications, the IDE or both. In contrast to Delphi, packages are not limited to libraries and they can be OS independent. The IDE automatically compiles packages if some of its files are modified. 17.2 One unit for only one platform / conditional unitĪ Lazarus package is a collection of units and components, containing information how they can be compiled and how they can be used by projects or other packages or the IDE.17.1 One unit per platform, several units with same name.16.2 For Delphians: I can not install a run time package, why not?.16.1 Typical scenario for a run time and design time package.

15 Your package provides a library, how to extend the linker search path in all your projects.

11 Create a package with a unit that has the same name as the package.

10 Adding existing components to a Package.

5.4 Creating a package for your common units.
