QUESTION

Link dll against static build of QuaZip using Qt5.12 in VS2017

Asked 2022-Mar-15 at 11:05

I'm trying to link a .dll against a static builld of QuaZip library to get rid of the quazip.dll dependency at runtine. Since I've ran into a dependency conflict at production because a customer is using other third party applications in the same process where my .dll is uncluded, which are also using the quazip.dll but a legacy version. My steps were first to statically compile the zlib dependency as instructed in other posts with the ZLIB_WINAPI flag. Then I compiled QuaZip also with the appropriate ZLIB_WINAPI flag and QUAZIP_STATIC. As zlib.h I have used QtZlib/zlib.h header like in this post recommended. In my .dll project I've also tried to set all the mentioned flags (QUAZIP_STATIC seems to be necessary). Now when I try to compile my .dll I get the following errors

1>quazip.lib(zip.obj) : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol "__imp__z_deflate@8" in Funktion "_zipCloseFileInZipRaw64@16".

Ok, three days of agony and I have the solution. I recompiled the zlib, this time not using the provided project file in \contrib\vstudio\vc14, but generating my own with CMake. Then QuaZip linked against it with the flag QUAZIP_STATIC. I then set this flag in my project, which uses QuaZip and linked it against the built quazip.lib and its dependency zlibstatic.lib. Now the library is built into my .dll statically and I no longer have to supply the quazip.dll that caused the conflict.

QUESTION

Qt Android Directories

Asked 2021-Oct-10 at 09:27

I am concerned about two questions regarding how Qt works with Android directories.

For example, I want to download an archive via a library (QuaZip), but I need it to be downloaded along the path "/ storage / emulated / 0 / Android / data /", and then unzipped right there. But the problem is that the file is saved in the patch "/data/user/0/org.qtproject.example.NameApp". How can this be fixed? My code (it is unlikely that it works at all, but on Windows it would work for sure):

On your first question about Android/data r/w

On Android 11 Android/data is forbidden for app access without root, see docs1 and docs2.

For read/write to other locations:

The directory must exis or must be created (with QDir::mkpath() at once, or with QDir::mkdir() by subdirectories sequentally, because it can't create trees of directories).
QFile must be closed before rename.
App must have android.permission.READ_EXTERNAL_STORAGE and android.permission.WRITE_EXTERNAL_STORAGE permissions.
At last, approve file access permissions manually in Android apps settings after app is deployed from Qt Creator. And you also may have to launch app manually, because there were reports about different app behavior when launched from IDE and and when launched manually from device.

This code worked for me (Android 11, Qt 5.15.2):

QUESTION

How to decompress gzip containing multiple files?

Asked 2021-Apr-19 at 15:15

Is there an option, using zlib or boost, to unpack a gzip archive containing several files? All options which I figured out were for 1 single file in archive.

I know about minizip, quazip and other useful libs, but I need to try to find an option without additional libraries.

gzip doesn't compress multiple files. It only compresses one file. The reason you can't find a way to extract gzip archives is that they don't exist.
