What can we do to make it smaller?

while running configure scipt pass -nomake examples -nomake tests parameters. It will save you about 60Gb of space.

@Taz742 I thought you were talking about static Qt build taking up a lot of space and not about application with statically linked Qt.
In this case What Qt modules do you use? What is your app size if you link Qt dynamically?
If i recall correctly my application with just core and gui modules took about 15Mb of space. -

I use Qt 5.7
My project is the following: I need only .exe which reads .xml file, this xml is written in the file's address that should be downloaded and put in my specified location.
I have prepared everything but I do not want to use my program to duplicate .dll and other files. I need only .exe and be too small. -

@Taz742 Given the level of customisation provided there is no way for Qt to deliver pre-compiled binaries. It's just a series of config options to use when building Qt from sources. use
configure --list-featuresto see them all -

@VRonin
Unfortunately, there are many big for me.
I started writing my project Native c ++ (Dev-Cpp 5.11 TDM-GCC 4.9.2), but I can not write http downloader.
Can anyone help me?wrote on 29 Jun 2017, 10:29 last edited by@Taz742 said in Qt Static Build Is Very Big:

Oh god, please no! Use a proper IDE. Qt Creator is already there for you

You can use libcurl. it's in C but it's only 300KB
P.S.
You are probably going off topic here give this is a Qt forum -

When I started learning programming (Algorithm) Dev was my friend and I love it very much :)@VRonin said in Qt Static Build Is Very Big:

Yes there is Qt but in this particular case only .exe need and very small.
@VRonin said in Qt Static Build Is Very Big:

And where to use Libcurl, tell me the language of programming where I use Libcurl and then I will only have .exe 300KB.
Please teach me :)) -

I guess it's a bit like my love of escargot.

There is no relation between what IDE you use and the complied output
And where to use Libcurl, tell me the language of programming where I use Libcurl and then I will only have .exe 300KB
Almost all C++ compilers can compile and link to C code. Just follow the tutorial

Just a note
Did you try
https://upx.github.io/
Its the charactermap sample static compiled. and then compressed.
Its fully transparent for the user and very fast decompressor.

It works really well, however, if your problem is transferring the file around

Well it decompresses to memory so unless its a size memory issue (on target), it should not matter.
But of course it wont be as lovely small as curl + pugixml :)
