About the dlls that you need to run the project exe
-
Hey guys , sorry for asking lots of questions , yesterday I posted a two questions and one of them was about running the exe , and there's a guy that said there's two ways of doing it ,
1- you copy all the dlls u need
2- static build
I read about static build but it was too hard to understand and also it's going to mix it up or something so the final exe would be as big " I think "
so I have two questions:
1- what can I do to reduce the size ? because I've made a project and it does a simple thing yet the size is around 30mb " because of the dlls " , please try to explain because English is not my first language also I'm new :)
2- I read about upx and they said it reduces the size of dlls , so I tried to use it , but when I try to pack the dlls it says " this file does not have a program associated with it for performing this action " even though my program is in the same folder with the dlls.

Hi,
about the size 30 MB: your app and Qt dlls are maybe 10 MB together, the rest is for the 3 ICU51 dlls, used for "unicode and internalization":http://site.icu-project.org/#TOC-What-is-ICU-If you don't need full Unicode support for all the world's languages etc, it should be possible to rebuild the ICU libraries to a much smaller size.
-
Yup , about 80% from the size is from ic..51.dll files , which are 3 as you said, yes please if you could tell me how to manage them and get rid of the unwanted languages that would be great.
, also what about upx ?

Hi,
This user has produced a "dummy" version of ICUdt51.dll, which reduces the size from 20+ MB to 600+ KB: http://qt-project.org/forums/viewthread/38489/

You're welcome :)

Thanks guys ,
thank you jksh for the link , I'll check it out , but can you link a post that tells you how to do it yourself ? I searched and found that there's a qconfig but I can't find it in my computer , why ? i have Qt 5.2.1.

I used the post's custom dll but it doesn't work , it gives me error and when I tried to put on the bin folder in the qt's folder , and recompile my program it doesn't gives me error it just crashes! I'm using qt 5.2.1 debugger is msvc 2012

Hi,
It looks like the versions are incompatible.
You have two options:
Compile ICU yourself to create a minimal package, using your compiler.
Compile Qt yourself without ICU support.
I don't know how to do #1, but I use "these instructions":http://qt-project.org/wiki/Building-Qt-5-from-Git for #2
