how to statically compile a program with qt libs?linux platform

I learned that I could statically compile qt libs and then statically compile my program.
I have statically compiled qt libs and I want to statically compile my program.

for example,if I need

QtXml,QtCore,QtGui,phonon,

and I have these libs of *.a files under /opt/qtstatic/lib,
how do I write my .pro file to statically compile my program?

also I wrote my program in a dynamic qt environment,do I need to make any change to my source code?

thx

you don't have to do changes in your source code, you only have to to add

Code:

---

CONFIG += static

---

in your pro file.

I'm sorry but:
I tried it but it seems nothing changed,the program still can't be used on a computer without qt.
Do i need to specify the location of those static libs in .pro file?

no that's all. Of course you must use the qmake of your static build, that the right libraries get bound. For Linux also have a loot at: [WIKI]Building static applications[/WIKI].

well,following your help,it is OK now,
I didn't make install_qmake before,I think that is the reason why I failed.

May I ask you another question?
After statically build my program,the phonon backend module doesn't work,
it works when I use dynamic build,
What should I do to make it work?

thx again.

You need to static link all the phonon plugins too of course.
And all the other plugins you use too (image formats, etc...)

May I ask How to static link those plugins?
Do I need to reconfigure qt adding argument
-phonon-backend?
or are there any other way?

thx

I found that most of those plugins in my static qt directory has .a files
but /plugins/phonon_backend is an exception
there is only a libphonon_gstreamer.so in it,no .a file!

and then I configured and made again with argument -static -phonon-backend
but it didn't change anything

then I look into the shared qt dirctory installed by the .bin file I downloaded from qt's website.
Look in /qt/plugins/phonon_backend ,there is also no .a file while all the other folders in that directory has both .a and .so files of the same name

So I am totally confused now
I have found that static compile can solve my original problem
!!!but the problem now I think is that
I statically compile qt,but I can't get a static phonon_backend lib

what's wrong with my Qt?will a totally reinstall and remake for static solve this problem?
plz help me.
best wishes to everyone.
I hate confusion really.

I found the answer in qt's document.

http://doc.qt.nokia.com/4.7-snapshot/plugins-howto.html

it say that static program can only link static plugins.
and qt doesn't provide static phonon_backend plugin,
so I can't build a static program with phonon backend.

thank you everyone for your answer.
best wishes.
