There are two kinds of libraries in Eiffel: precompiled Eiffel libraries and C libraries.
|
|
|
|
To use an Eiffel precompiled library:
|
|
* Open the [[Group Options|Project Settings]] dialog.
|
|
* Add a new precompile group to your target.
|
|
* You must [[Generating executables|recompile]] your project from scratch for the changes to take effect.
|
|
|
|
{{note|You can only use one precompiled library at a time in a project. To use more than one, you should precompile all the libraries you want to use together in a single precompiled library. }}
|
|
|
|
To use a C library:
|
|
* Open the [[Externals Options|Project Settings]] dialog.
|
|
* Add an include external for the directory where the header files needed to use the library are.
|
|
* Add an object external for each object file needed to use the library. These files can be either library files (.lib, .a, etc) or object files (.obj, .o, etc)
|
|
* Click '''OK'''.
|
|
* You must [[Generating executables|recompile]] your project for the changes to take effect.
