[Lazarus] LCL_FULLVERSION is not recognized

[frans via Lazarus]

Hi.

I use Lazarus 1.6.4 (temporarely) and lazarus 1.8.4 on Windows 10.
I need to use the LCL version but I can't get it to work properly.
I use the following code:
  {$IFDEF LCL_FULLVERSION > 1080000}
  {$ELSE}
  {$ENDIF}
Compiling the program give me the message Warning include environment
"LCL_FULLVERSION" not found in environment. But this is the way I fount
on the lazarus forum.
What am I doing wrong? And where can I find a list of all Lazarus
environment variables?

Where did you find this on the forum?
Because you shouldn't use {$IFDEF } but {$IF } (because you are using an
expression)

So:
{$IF LCL_FULLVERSION > 1080000}
{$ELSE}
{$ENDIF}

If you use {$IFDEF it will check if "LCL_FULLVERSION > 1080000" is
defined, which it isn't.

Also see http://www.math.uni-leipzig.de/pool/tuts/FreePascal/prog/node4.html

B.T.W. You need to include "uses lclversion" because LCL_FULLVERSION is
declared there (otherwise you get a ansistring error message).

Some other constants:
