I've already written about my problem but I still can't solve it. Here it is.
I need to write some library under FASM but include functions' sources only if they appear in main code and do it at the end of main code.

In MAIN.ASM:

Code:

include 'my_lib.inc'
lib_call some_func arg0, ... argN

In MY_LIB.INC

Code:

if ~defined LIB_INCLUDED
        LIB_INCLUDED equ 0xFF

        macro lib_call f_name*, [args]
        {
                LIB_#f_name args
        }

        include '%asm_lib%/p1.inc'
end if

In P1.INC

Code:

if ~defined P1_INCLUDED
        P1_INCLUDED equ 0xFF

        macro LIB_some_func [args]
        {
                include '%asm_lib%/some_func.inc'
                common call P1_some_func
        }
end if

In SOME_FUNC.INC

Code:

if ~defined LIB_SOME_FUNC_INCLUDED
        LIB_SOME_FUNC_INCLUDED equ 0xFF

P1_some_func:
        ; 'SOME_FUNC' code
        ret
end if

I understand that line

Code:

include '%asm_lib%/some_func.inc'

will placed right here where it is but I need it in another place (at the end of MAIN.ASM)
Is this problem solvable?

I think your problem is with the way you use "define". Try this.

In MAIN.ASM:

Code:

macro if_ndef name { match =name,name \{ }
include 'my_lib.inc' 
lib_call some_func arg0, ... argN

In MY_LIB.INC

Code:

if_ndef LIB_INCLUDED
        macro lib_call f_name*, [args] 
        \{ 
                LIB_\#f_name args 
        \} 

        include '%asm_lib%/p1.inc' 
}
define LIB_INCLUDED

In P1.INC

Code:

if_ndef P1_INCLUDED
        macro LIB_some_func [args] 
        \{ 
                include '%asm_lib%/some_func.inc' 
                common call P1_some_func 
        \} 
}
define P1_INCLUDED

In SOME_FUNC.INC

Code:

if_ndef LIB_SOME_FUNC_INCLUDED 
P1_some_func: 
        ; 'SOME_FUNC' code 
        ret 
}
define LIB_SOME_FUNC_INCLUDED

May be I'm a lamer, but fasm says

define P1_INCLUDED - illegal instruction

FASM's default "proc" macro doesn't generate the code if procedure isn't used anywhere, if this is what you wanted. But this is task of assembler, not preprocessor.

Oops, sorry forgot this

Code:

macro define name { name equ defined }

Place just after the if_ndef and before you use it.
