When building QuaZIP QUAZIP_BUILD should be defined but isn't - configuration process defines in error completely useless 'quazip_EXPORTS' instead.

This is because QuaZipFile is declared like 'class QUAZIP_EXPORT QuaZipFile' and QUAZIP_EXPORT needs to resolve to Q_DECL_EXPORT for dll and to Q_DECL_IMPORT for application, based on whether QUAZIP_BUILD is defined or not.

Rebuild again and you'll get lots of warnings and one error C2491: dllimport static issue on QuaZipFile::staticMetaObject.

Open preferences for quazip project and add path to Qt's copy of Zlib to C/C++->General->Additional Include Directories: $(QTDIR)/src/3rdparty/zlib.

Open soltion with VS and build - you'll first notice that it can't find 'zlib.h'.

Use CMake to configure and generate VS solution for QuaZIP.

I tried QuaZIP 0.4.3 on Windows with VisualStudio 2010 - there are still issues but can be resolved easily. It may be possible to tackle all those compiler errors, but a word of caution to anyone looking down this path. Update 2: After completing this task on my Linux build environment, I discovered that QuaZip doesn't work at all with the Visual Studio compiler. There is an example in the download package (in the 'tests' dir) that shows very clearly how to zip up a directory of files.

Update: The QuaZip library looks really great. Is there a standard way to combine bytestreams from multiple files into a zipped archive, or maybe there is a convenience function or method that would be available in the Boost iostream library? How do I zip a directory of multiple files, including subdirectories? I am looking for a cross-platform (Mac, Win, Linux) solution I'd prefer not to fire off a bunch of new processes. I understand how to compress single files and bytestreams using, for example, the qCompress() function in Qt. I'm working on a project using C++, Boost, and Qt.
