Compiler creates executable with different filesize

[Fenix]

Hi,

I was interested what the assembler source of my program would look like, so - as I didn't know how to set the /COMMENTED flag in the PB IDE - I compiled the program using the dosbox.

To my surprise the executable was about 12% smaller than the one compiled using the PB IDE (2.114kb [cli] to 2.405kb [PB IDE])? First I thought there might be some icons missing but that wasn't it, the program works fine with no missing parts. Why is that?

The program was compiled with

Code: Select all

pbcompiler source.pb /COMMENTED /CONSTANT PB_Editor_BuildCount=0

and I use the following command sets in the program:

Code: Select all

; The header must remain intact for Re-Assembly
; 
; ToolBar
; Thread
; String
; StatusBar
; Sort
; Requester
; RegularExpression
; Process
; Preference
; OnError
; Music
; Sound
; SoundPlugin
; Menu
; Math
; LinkedList
; Library
; Keyboard
; Mouse
; Screen
; Sprite
; MultiMediaBase
; ImagePluginBMP
; Engine3D
; ImagePluginPNG
; Http
; Network
; Gadget
; System
; Window
; Font
; File
; Event
; Map
; Desktop
; DatabaseSQLite
; FileSystem
; Date
; Database
; Cipher
; Array
; 2DDrawing
; Image
; AlphaImage
; ImagePlugin
; Memory
; Object
; SimpleList
; :System
; ADVAPI32
; COMCTL32
; KERNEL32
; USER32
; :Import

Two other - smaller things:
1) When I tried to compile via cli I got an error message "Constant not found: #PB_Editor_BuildCount". I remember that even in the IDE I had to type it in myself - it wasn't available in the autocomplete.

2) When I tried to add it (using /CONSTANT) I wrote /CONSTANT #PB_Editor_BuildCount the compiler crashed. Removing the "#" and it works fine. Howe come?

In the IDE do you have any of the compiler options; Unicode, Threadsafe, XP themes, request admin support for Vista and so on?

Some of these will involve the compiler using different routines (e.g. unicode versions of functions). Others will involve the compiler adding various manifests to the exe's resource section etc.

You need to make sure that the compiler switches you give at the command line match exactly those which the IDE will give based upon your settings.

btw, you might want to take a look at : http://www.purebasic.fr/english/viewtop ... tedASM.exe

Yes, that's it. Using the settings from the IDE in the CLI produced the same size of the exe.
Thanks srod, again!

Nice, made it's way to my tools menu

You'll have to alter the source of the tool and recompile if you want the ASM to reflect Unicode and/or threadsafe etc. As it is it just generates ASM without either of these switches set.

Yup, I added the switches for /unicode and /linenumbering
