Delphi Compiler Error
E2100 Data type too large exceeds 2 GB
Reason for the Error & Solution
You have specified a data type which is too large for the compiler to represent. The compiler will generate this error for datatypes which are greater or equal to 2 GB in size. You must decrease the size of the description of the type.
program Produce;
type
EnormousArray = array [0..MaxLongint] OF Longint;
BigRecord = record
points : array [1..10000] of Extended;
end;
var
data : array [0..500000] of BigRecord;
begin
end.
It is easily apparent to see why these declarations will elicit error messages.
program Solve;
type
EnormousArray = array [0..MaxLongint DIV 8] OF Longint;
DataPoints = ^DataPointDesc;
DataPointDesc = array [1..10000] of Extended;
BigRecord = record
points : DataPoints;
end;
var
data : array [0..500000] OF BigRecord;
begin
end.
The easy solution to avoid this error message is to make sure that the size of your data types remain under 2Gb in size. A more complicated method would involve the restructuring of your data, as has been begun with the BigRecord declaration.
