Linkobject mode

EEC Documentation

LINKOBJECT in source switches on LINKOBJECT mode.

In this mode, ECX will output an ELF linkable object.

This is mainly useful if you want to link some E code together with some C code or so, by using an external linker.

Notes:

Code from modules can not be used from linkobject. Anything else from a module can be used.
You can not use the internal functions in linkobject mode. If you attempt to use them, the linkobject will be having external references to the functions that you used. This way if you have another linkobject with replacement functions in it, just link it with your linkobject.. and voila.
You can make use of external functions/labels from your linkobject by using the USES keyword after LINKOBJECT: Example:
```
  LINKOBJECT USES
    Bla(),
    alabel,
    AnotherFunc(x,y,z),
    YetAnotherOne(i:LONG, f:DOUBLE) (DOUBLE,LONG)
```
You can export globals, procedures and constants from your linkobject, just put EXPORT in front of the stuff you want exported.
Be aware that some language constructs might need access to internal functions, which means these functions have to be available from some other linkobject when linking. NEW/END needs access to FastNew()/FastDispose() and int->float conversion needs a special function. Nilcheck needs access to Throw() function.
External librarybases needs special handling. C uses DOSBase, E uses dosbase… etc. EXPORT DEF has an extension in LINKOBJECT mode for this situation: Example:
```
OPT MORPHOS
LINKOBJECT
MODULE 'exec'
EXPORT DEF execbase AS SysBase
```
No default modules are automatically loaded.
This is experimental stuff for now…
