Create a DLL and import library

Syntax

`

-dll

`

Description

The -dll compiler option creates a dynamic link library. This creates a DLL under Windows (including the import library), creates a .so under Linux, and a DXE under DOS.

Note: Same as -dylib

The intrinsic macro __FB_OUT_DLL__ is set to non-zero (-1) if the -dll option was specified, and set to zero (0) otherwise.

Platform Differences

• On windows, dynamic link library is created with ".dll" file name extension and import library created as "lib<name>.dll.a" file name
• On Linux, dynamic link library is created with ".so" file name extension
• On DOS, dynamic link library is created with ".dxe" file name extension and import library created as "lib<name>_il.a" file name
