outsource RTTI

[paule32]

Hello,
by creating class's I have many VMT and other Information's in the executable Image.

In my main modules I tried:

{$TYPEINFO OFF}
{$M-}

But there was not help.
So, give it a Command Line Option to outsource the RTTI into an external File ?

I know you are not a native English speaker; however, there is a phrase that is used quite often here in the states and that is:

 "You are up a creek without a paddle"

 I am sure you have an equal expression in your language

You can't get rid of all RTTI.

Any class that has a parent with $M+ / published (like TPersistent) will have RTTI -- never mind what you do in your units.
You would need to recompile all rtl/lcl sources after changing them.

Even without that:
- classname
- a few others
will always be there. No way to remove (other than modify the compiler)

Some info on enums/sets will always be included.

Info an managed types in dynarrays will be there. That is actually needed, to alloc/free mem for entries in the array.

Not sure what else...

Hi
I asked my wife, who's born in Hamburg and she said: "There's no direct translation of - Up Shijt Creek without a paddle - in german"

is it possible to shrink the Meta Information's with a kind of zip Stream when running the FP Compiler ?

In one of my Project I worked on, I introduce gzip -9 packed Resource Files that I outsourced to external DLL Files (mostly for Localization stuff).
After gzip, I bundle the packed Resource Files into new Resources Files.
So, I can use Windows win32api Functions and Procedures to handle Resources (after unpacking it).

This is a little bit not comfortable, because I use a Batch Script File with calling Command's on the Windows Console for each Step ... But it seems to work.

You could always try the Advanced record or older Object model to reduce that a little.

Eine passende deutsche Übersetzung wäre:

"Du sitzt in der Klemme."

"Du steckst in der Patsche."

"Du bist aufgeschmissen."

"Du bist in der Tinte."

No, there is no such thing and there will be no such thing.

No, this is not possible, because the RTL needs to be able to access the information.

The RTTI is part of FPC's language implementation of Pascal. If you don't want it, then don't use FPC.

I don't would make FPC bad ...
I love FPC because it is free, and faster than GNU C/C++ Compiler (gcc / g++).
It give bottelnecks to each DSL Compilers ...

But, if I have the right Person's, FPC can a powerful Tool.

Why don't you compile to assembler, and make a sorter yourself?

Hex entry keypad or at least a Machine language monitor to poke around in memory.

@marcov:

good Idea ...

me:
- I am come from Delphi and C++ Builder Line ...
- was migrating to FPC only few month ago ...
- lazy a little bit to do test practisim on the Posibilities of FPC ...
