Trying to test for a certain minimum version of FPC.
Have got FPC version 2.7.1 [2011/09/17] for i386 on Windows.
What am I doing wrong?
program conditional;
{$mode objfpc}{$H+}
uses
{$IFDEF UNIX}{$IFDEF UseCThreads}
cthreads,
{$ENDIF}{$ENDIF}
Classes;
begin
//How should I use FPCVULLVERSION in conditional compilation?
{$IF $FPCFULLVERSION > 20200}
writeln('Version newer than 2.2');
//Error: Compile time expression:
//Wanted BOOLEAN but got INTEGER at IF or ELSEIF
{$ENDIF}
//so maybe the IF wants a precooked boolean result
//let's try some brackets
//Tried to apply Programmer's Guide 2.4 on Compile time expressions:
{$MACRO+}
{$IF (FPCFULLVERSION > 20200)}
//Error: Compile time expression Wanted STRING but got INTEGER at
//"FPCFULLVERSION > 20200"
writeln('Version newer than 2.2 another try');
{$ENDIF}
//adding a $:
{$IF ($FPCFULLVERSION > 20200)}
//Error: Syntax error while parsing a conditional compiling expression
writeln('Version newer than 2.2 yet another');
{$ENDIF}
end.
