New User - Compiling Problem

[Leledumbo]

Here is the my command line parameters to achieve 1.50Mb with Windows XP

Not look much different from me. Except that I use -O3, -CfSSE3 and -OpPENTIUMM. And of course it's also applied to RTL and FCL, probably you miss the last two.

Is anybody worried about file size when downloading the application? I doubt it.

Agree, but some of us are just size freak

That's it! I never rebuild RTL and FCL, only LCL

Don't be fooled, I am on your side and think 1,5 Mb is normal from a Lazarus point of view, I just want to be sure my "starting point" is well optimized, and thanks to you Leledumbo I realized I can do better.

the 1.5 MB  (or 1.6) are the current correct minimal size.

Because the compiler can not know what resources are later loaded (like maybe a gif, or png is opened from an external file). So all the decoders must be included, even if you do not use them.
Probably some icons for error/warning dialogs, that could happen.
Similar a lot of other stuff is included. (but I do not have a full list)

I have made a test once. If you do not use gfx (except the program icon) => you can modify the LCL and throw out the code from the graphic unit (it is a bit more work than it sounds). That saves about another 100 MB.
But then it will affect the LCL for all apps, and you can't use it any more for apps that require gfx....

Yep,

I just built fpc 2.4.1 adding smartlinking and so on and built again with this new compiler with the same result. By the way seeing default options for building fpc it seems this is already the case.
