Yes, it does, if you distribute your software on diskette.

You need to take into accound that those 1600 contain a lot of things
the 500 don´t contain, like:

PNG support, XML library, Cross-platform, etc.

Why don't we make an option during the compilation, where you can
choose the EXE size, the very small, or the very large EXE.

if it was possible it would already be there (don't you think ?)

I think it is possible, you must just let execute the strip.exe after
the first compiling, and then also the upx compression. Like this
Compile project /: Project is compiled, but not visible, executes
strip on the exe created, executes upx on the exe created, starts the
executeble.

The use of upx has only some artificial gain, I won't recomment in
using it (I could also store it on a compressed disk, it has the same
effect)
What you describe is already possible, look at the last (compilation)
tab of the project settings. However we wont add strip as a default
option, since in our opinion debug info is way more important during
development than one single strip during release.
We are currently thinking on how to implement different projectoption
settings (like Debug or Release)
In that case a user can easely swich between for instance Debug and
Release build.

Yes we need it especially after Delphi2007 have it finally, but after
i moved to Lazarus  .
BTW i use external batch file to build my projects with switches for
release, include making the setup.

I´m trying to create an integrated way of finalizing the exe with
strip and upx. So I created a simple generic batch file based on a
personalized (working) file I have on my project:

Code: [Select]@echo off
copy %1.exe %1t.exe > nul:
strip -s %1t.exe
upx %1t.exe
del %1.exe
ren %1t.exe %1.exe


I put this file (prod.bat) in the Lazarus dir, and configure a Custom
Tool directed to it with $ProjFile() as parameter and $ProjPath() as
working dir. I got only "The system cannot find the file specified."
as return. Has anyone tryed to do something similiar and knows what
I´m doing wrong ? Doesn´t Custom Tools work with .bat files ?

Why don't you simply create a shortcut on your desktop?

If you use UPX  intensively, soon you will know why it is not
recommended.

And why is that ?

Because it fails.
