ABC: Conditionally setting globals external 2003-01-30 -- Steve Rothkin Newsgroups: TopSpeed.Topic.Suggestions
I was able to take care of this with a few simple modifications of the
templates in C5.5, but I would like to see this as a standard option
in the future.
Basically I have 2 DLLs each built with different dictionaries (NO
files in common). The lower level DLL has to define all of the ABC
stuff (or else the DLL doesn't build). The 2nd DLL needs to reference
functions from the 1st DLL, but also needs to generate the
application/dictionary-dependent ABC globals (filemanagers,
relationmanagers, etc.). With the default ABC templates, this results
in the 2nd DLL giving duplicate defines on
GlobalRequest
GlobalResponse
VCRRequest
There may be others depending on options used for building, but these
are the ones that came up for me.
The solution was very simple so hopefully it can be incoporated into
C6:
In abchain.tpl
on the general tab add:
#ENABLE(~%GlobalExternal)
#PROMPT('ABC globals defined in other
DLL?',CHECK),%ABCGlobalsDefinedExternal,AT(10,,180)
#ENDENABLE
in the Global Template Declarations section add:
#if(%ABCGlobalsDefinedExternal)
#SET(%ABCGlobDllAttr,',EXTERNAL,DLL')
#else
#SET(%ABCGlobDllAttr,'')
#endif
in abprogrm.tpl
wherever one of these is defined without an external attribute, add %ABCGlobDllAttr to
the end of the declaration
i.e.:
GlobalRequest BYTE(0),THREAD %ABCGlobDllAttr
GlobalResponse BYTE(0),THREAD %ABCGlobDllAttr
VCRRequest LONG(0),THREAD %ABCGlobDllAttr
in abbldexp.tpw
at the %BeginningExports embed change:
#IF(~%NoGenerateGlobals))
#INSERT(%AddExpItem,'$GLOBALREQUEST')
#INSERT(%AddExpItem,'$GLOBALRESPONSE')
#INSERT(%AddExpItem,'$VCRREQUEST')
to:
#IF((~%NoGenerateGlobals) and (~%ABCGlobalsDefinedExternal))
#INSERT(%AddExpItem,'$GLOBALREQUEST')
#INSERT(%AddExpItem,'$GLOBALRESPONSE')
#INSERT(%AddExpItem,'$VCRREQUEST')
Thanks,
