Link all Qt libs statically.

[psih128]

Hi

I'm about to start working on a new project. One Of the requirements is to build an application consisting of a single executable file, which would run without any installation/setup/etc. Pretty much how things work on Macs.

Is it possible to link Qt libs statically? How do I do this under windows?

Thanks
Anton

Hi,

take a look at the faqs http://www.qtcentre.org/forum/faq.ph...compile_static

:-)

Yes, it's possible

If you are using MinGW:

./configure -prefix /Developer/Qt/4.4.3 -platform win32-g++ -qt-zlib -qt-libpng -qt-libjpeg -static -release

Kind regards,
Xesc.

oops, what a shame
I should have RTFM before asking

Thanks

err.. Looks like it's not as easy as I tought. Qt libs are linked statically and there is not problem.

What I want to do not - is to link to Qt libs to Visual Studio CRT library statically. And then link to Qt libs, so there are no external dependencies. Is it possible? How do I do this?

Thanks
Anton

In menu :

Project/Properties/Configuration Properties/C/C++/Code Generation

see the "Runtime Library" choices. The choices that do not contain "DLL" are the static linking options.

i's not really a solution. Qt libs are linked against dynamic runtime by default. So if we change the project settings as you suggest the application will be linked against a different runtime, which obviously wont link properly.

So I'm looking for a way to compile static Qt libs statically with CRT linked statically.

Thanks, but this is not what I'm looking for.

CRT still wont be compiled into Qt binaries. The resulting Exe's and Dll's will be dependent on CRT Dll's

It's all there, just read through the article. Pay attention to "Building static Qt on Windows".

I read the article properly.
If you perform all the steps described in the article you will end up with a large exe containing all Qt modules, but depending on CRT. For example building using Visual Studio 2005 will add a dependency to MSVCR80.dll. Most of the systems have VC++ 2005 Redist installed, but some dont. On those few systems the application wont run.

Did you read the step about editing mkspecs: [WIKI]Building static Qt on Windows with MSVC[/WIKI]?

This seems to be exactly what I need!
Thanks a lot - finally this is resolved
