Huge Qt directory under Windows Vista

[hoehm]

Hi

I just downloaded and installed Qt4.5.1 on my Vista system.
After configure everything was build and I have had no problems developing Qt applications with MSVC2008 by means of the Qt offered plugin.
The only problem is that the Qt directory is approx. 10 GB large; there are many tmp subdirectories.

Any hind on this?

Hey, you build the entire Qt library (and presumably examples and demos), how could you expect the build files to be so small and so few that you wouldn't notice them?
All the extra size comes from intermediate build files, often called "object files" which are at the last compilation stage linked together to form the executable and these files are not deleted after the build because the makefile system allow them to be reused for subsequent builds as long as the associated source files are not modified. To free space you just need to remove these files (you could just do a make clean if you made sure to backup the executables (EXEs, DLLs and LIBs) which would also get deleted in the process and you probably don't want that to happen).

My qt on Vista had 10G. Now with make clean qt has 5Gb

Thx for your response.

I guessed that this step should reduce the size of the directory, but thought that this deletes also important dlls. Can I run configure with the -fast option to avoid building all the examples stuff?

The -fast option only affects makefile creation. Use the -nomake option (with proper parameter) to disable build of examples and/or demos. Cleaning object files (by hand or through make clean with proper backup) will still be needed to significantly reduce the size of your Qt dir since the libs are responsible for most of the intermediate files.
