Hello huurd,
I use dwt+dwtx, a hello word exe size is 22M, after I use upx the size
is 800kb.
exe file appears to be a lot of meaningless repeat, how to remove it?
22M is distastefully huge for a hello world example using dwt and dwtx :(.
Like other's suggested, maybe debug info is getting compiled in due to a
-g switch.
The file size still may end up being several megabytes, though, even without
the debug info. This is more of an annoyance, than a hindrance. DWT has
a lot to offer; so most people end up coping with the size issue, especially
if they know they can use something like upx to squeeze things tight.
I can't exactly remember what the cause of this is, but I think it has something
to do with scads of "hidden" D symbols (moduleinfo?) produced by the D compiler
for projects that have a combination of (1) tons of modules and (2) many
interdependencies amongst modules such that even a small project ends up
linking in ALL (or nearly so) classes from the framework. This, unfortunately,
is one of DWT's weaknesses. I wish the language could help DWT by fixing
that, but I don't know if that is possible. Other alternatives that might
help reduce the problem (I think) is integrating multiple modules into one
file...but that tends to hinder the whole idea of organization and namespace
clarity. If DWT were to do this, it would also break import compatibility
with SWT. There are a few reasons why this approach is not desirable.
But I hear you. I really don't like unnecessary bloat either. It would
be great if we had some super smart tools that could pair things down a bit.
