Is there a way to determine SDAC version at compile time and, if the version is too low, generate an error? Something like {$IF SDACVer < 3550017} ... {$ENDIF}
Or do I need to parse the SDACVersion string variable at run-time?

You can't do this at compile time

Do you plan to include such feature in next versions? I think it shouldn't be complicated... Or at least an other constant/variable, that would be easily comparable without complicated parsing...

Please describe in details what you need it for.

I simply want to be sure, that nobody compiles the sources and uses the program compiled with too old SDAC version - if some important bug in SDAC gets corrected, each workstation that compiles the sources will be forced to update SDAC. And I don't also want to force to update all workstations, when the corrected bug wasn't important.
Example: I Want to let compile our current sources with SDAC 3.55.0.17 or higher, never with 3.55.0.16 or lower.

I really don't like writing complex algorithms like this
Code: Select all
function SDACVersionHighEnough: boolean;
const
ReqSDACVer: array [0..3] of integer = (3, 55, 0, 17);
var
currindex: integer;
currnumber: integer;
strpos: integer;
begin
currindex := 0;
currnumber := 0;
for strpos := 1 to length(SDACVersion) do begin
case SDACVersion[strpos] of
'.': begin
assert(currindex ReqSDACVer[currindex] then begin
result := true;
exit;
end else if currnumber = ReqSDACVer[currindex];
end;
if not absolutely necessary
I would like following:
Code: Select all
if SDACVersionNum < 3550017 then ...
do you see the difference?

Do you distribute components, based on SDAC? Or is there another purpose?

No, I don't distribute components. As already many times said - I simply want to be sure, that nobody in our company compiles sources with a wrong version of SDAC (for examples, if the programmer comes from holiday, he sees immediately, he has to update SDAC).

We will think about adding such variable. But it looks hardly necessary.
