Once the Eiffel definition file is created, the compiler will generate a set of files and will compile them to generate the Dynamic library into the <code lang="text">EIFGENs/target_name/W_code</code> or <code lang="text">EIFGENs/target_name/F_code</code> directory.
|
|
|
|
{{note|To generate and compile these files, you have to indicate the definition file that should be used in the [[Advanced Options|advanced node of the project settings]] of your system. This way EiffelStudio will know which one to use. If you do not specify any definition file, nothing will be generated. }}
|
|
|
|
The set of files is composed of:
|
|
* <code lang="text">EIFGENs/target_name/W_code/</code>'''system.def''' (or F_code)
|
|
* <code lang="text">EIFGENs/target_name/W_code/</code>'''edynlib.c''' (or F_code)
|
|
* <code lang="text">$(ISE_EIFFEL)/studio/config/$(ISE_PLATFORM)/templates/</code>'''egc_dynlib.template''' <br/>
|
|
this file will be copied during the compilation into the EIFGENs/target_name/W_code/E1 directory as '''egc_dynlib.c'''
|
|
* <code lang="text">$(ISE_EIFFEL)/studio/spec/$(ISE_PLATFORM)/include/</code>'''egc_dynlib.h'''
|
|
* and the Makefile
|
|
|
|
The ''system.def'' is only used on windows, it is the definition file used to generate a DLL when linking.<br/>
|
|
Information about the DLL
|
|
<code lang=text>LIBRARY demo.dll

This part concerns the run-time. It initializes the run-time and reclaim Eiffel objects.

The exported for the BAR class:
|
|
<code lang=text>; CLASS [BAR]
|
|
get_string
|
|
print_bar
|
|
</code>
|
|
The exported for the ROOT_CLASS class:
|
|
<code lang=text>; CLASS [ROOT_CLASS]
|
|
make
|
|
foo
|
|
test_bar</code>
|
|
|
|
|

The ''edynlib.c'' file is the interface between the Eiffel system and the C code. It contains the declaration and the implementation of the function used to directly call the eiffel feature with its real name.
|
|
|
|
The <span> ''egc_dynlib.c'' </span> and <span> ''egc_dynlib.h'' </span> files are used for operations performed by the run-time.
