qt with visual studio 2005; lib problem

**jambrek** · 29th January 2008, 13:45

Hello,

I use Qt 4.2.0 open source with visual studio 2005 and I cannot load qt libraries because I have *.a files in my qt\4.2.0\lib directory, and a need to have *.lib. How could I convert *.a into *.lib? I work in C++. There is In that lib directory a read me file witch contains: "If this directory is empty, you probably forgot to compile the Qt library." How I can compile Qt libraries, and got *.lib files?
When I create project as makefile project I can include that libraries, but I cannot load any other libraries (I need to load my *.lib). Because I created console application project. I set up qt parameters as described in following file: http://mm-werkstatt.informatik.uni-a...als/qt2005.pdf

Thanks a lot!

you need to build qt with msvc compiler.
to do so you need to run configure with the platform parameter.
look slike this:
configure -platform win32-msvc2005

Please make sure this is the valid parameter for your Qt and VS version.

Hi DeepDiver,
Thanks for your reply, but I already done that. I typed:
qconfigure msvc2005 -qt-gif -plugin-sql-odbc -plugin-sql-sqlite.
I'm successful build my makefile project and ran my Qt application, but in makefile project I cannot add my library files (*.lib), and I make a console application project, but win32 application could not load *.a libraries. I need to convert *.a into *.lib.

There is something totally wrong with your qt build.
*.a means Qt has been compiled with gcc/mingw.
*.lib is created by msvc.

there is NO way to convert *.a to *.lib - these are proprietory binary files.

I earlier used eclipse with mingw for my qt, and I set up parameters for mingw. I reconfigure parameters for visual studio, but *.lib files are not created. Should I delete any configuration and configure again? How can I clean earlier configuration?

Thanks

Come on! Just a little bit of do-it-yourself and try-and-error together with some rtfm!

Brute-force-hit: Delete the folder, extract qt-zip and configure it! ;-)

I downloaded new version of Qt (4.3.3) and configure (configure -platform win32-msvc2005) but it made *.prl files in lib directory. That did not created *.lib. I can't load *.prl libs too.
