Building static libraries

raaghuu

its in the bin directory(c:\QT\4.8.2_static\bin\qmake.exe)

u don't need to put your mingw32-make into Qt build folder, if you have your MinGW (by the way what's the version of your gcc? try to ask the command gcc -v in command line), just make your MinGW into your PATH - open Start->My Computer preferences and see System Paths there->find PATH and put C:\MinGW\bin with ;

then try to see qmake.exe in qmake folder and bin/ in your Qt build - can u see it? if you haven't got any troubles in compilation - it is strange that u don't have it

No, it is not, there is no exe nor dll in c:\QT\4.8.2_static\bin. Do I have to do again the build proccess? How should I modify it so qmake.exe is created?

raaghuu

well qmake is the first thing that is built...try this link http://developer.qt.nokia.com/wiki/How_to_build_a_static_Qt_version_for_Windows_with_gcc

i suppose u don't even need to compile qt by yourself

[quote author="gaminn" date="1340443863"]then I coppied mingw32-make.exe to C:\Qt\4.8.2_static and ran it. After few hours build was done.[/quote]
this is a mistake...the build cannot have completed(or even started)...mingw32-make alone doesn't do anything(i think)...you need whole minGW compiler(instead of copying, you should add the path of mingw32-make to the PATH environment variable)...
neways, i've tried building static libraries many times but some problem always crops up...and it doesn't have any advantage over distributing your program with dll's(except perhaps the no. of files to be given...but that problem can be easily overcome by packing all required files in a .zip or .msi package before distributing)....

I found out that in C:\QtSDK\Desktop\Qt\4.8.1\mingw\lib I have Qt static libs already compiled (there are files like libQtCore4.a, libQtGui4.a, ....). How can I tell compiler to link them?

I edited C:\QtSDK\Desktop\Qt\4.8.1\mingw\mkspecs\win32-g++\qmake.conf
QMAKE_LFLAGS = -static -static-libgcc
but this is obviously not sufficient.

What else should I do to link statically? Dependency Walker still shows dll dependecies of my exe.

Thanks

raaghuu

those are not static libraries...ref to my earlier post, your static build was not completed

gaminn

Libraries in C:\QtSDK\Desktop\Qt\4.8.1\mingw\lib are part of QtSdk-offline-win-x86-v1_2_1.exe installer (downloaded from qt.nokia.com), they weren't compiled by me. So I think I don't have to build them because I already have them. If I'm right there is only one thing I have to do - to instruct linker to link my Qt .pro project statically. Please help. Thank you.

raaghuu

the installer you used is the one i used too...it builds dynamically linking Qt libs... to link statically you need to build static version of qt(instructions for which are given in the many links provided in earlier posts)
