{$DEFINED ForEverybody} ?

[Fred vS]

Hello everybody. 

Im searching for a way to do a compiler-define for all the project.

Let me try to explain :

I have a project that have in uses section  a other file:

Program MyProject;

uses
myincludes ;

In myincludes i have that:

{$DEFINE  ForEverybody}

Sadly, if, in MyProject i use that :

{$IFDEFINED  ForEverybody}
do_something
{ENDIF}

It does not work, because ForEverybody is not defined in MyProject    

How must i do if i want that "ForEverybody" is defined also in MyProject (without to declare it in MyProject, of course)?

Many thanks.

2 ways
1) use include files ee {$I MyDefines} which is equivalent to redeclaring the same defines in the units you use use the line.
2) use the project options dialog select the other and in custom options add -dForEverybody, this will create a define that is global for the project that is defined in, you might want to make a default if you are going to use it a lot.

@ Taazz : many thanks 

So, it is not possible to create a define for all the project via a file in uses section ?

[taazz]

No, defines have only local scope.

Or put it on the cmdline (or lazarus "defines" settings)
