Where did you download QuaZip from ?

CharlieG

@SGaist
https://sourceforge.net/projects/quazip/

SGaist

Sorry, I couldn't reproduce your problem.

Which NDK are you using ? I have the r13b

CharlieG

@SGaist
Super...

I have just update my NDK (13.0 to 13.1) and the building works.

Thank you very much.

PS: mark to solved doesn't work ???

CharlieG

Re,

So, the building works, but I have 2 problems with the library :

impossible to find the quazip lib in the folder : /Applications/Qt/Qt5.8.0/5.8/android
I have this message wher execute the code undefined reference to 'JlCompress::compressFile(QString, QString)'

Do you have any idea about these problems?

SGaist

Where is the file located ?

The second error comes from the first. If the linker can't find the library it can't link to it thus you'll have symboles missing.

As for the "solving" part. You need to select ask as question from the "Topic Tools" button and then click on it again to mark the thread as solved.

The lib ? Precisely I don't know. With the QuaZip for Mac OS, I have /Applications/Qt/Qt5.8.0/5.8/clang_64/lib/libquazip.1.0.0.dylib.
But with QuaZip for Android, I have nothing in /Applications/Qt/Qt5.8.0/5.8/android/lib. Still, I have the headers in /Applications/Qt/Qt5.8.0/5.8/android/include

Yes, but here I only have two possibilities : Delete topic & Ask as question :(

SGaist

Did you install the library ?

You must first click on "Ask as question" and then when you open it again you'll have the "mark as solved".

CharlieG

@SGaist
Sorry, ... I hadn't to be awake...

The lib is installed in / libs / armeabi-v7a. So I copied it to /Applications/Qt/Qt5.8.0/5.8/android/lib for ease.

Thank you a lot.

@CharlieG
I am currently trying to use Quazip for Android, but I cannot use Quazip in QT and I am getting an error. What I did was I installed quazip-dev for Ubuntu and referenced it to my qt project, but it does not recognize the library. How did you install Quazip and compile it for Android? Can you please help?

I already told you in your other thread what you need to do:

Build QuaZip for android
Use this build to build your app for Android

What about following this suggestion?

Installing QuZip packages for your Linux distribution will not help you because those are for your desktop Linux, not for Android...

GulsahAkt

@jsulm I'm very sorry, after your answer I'm looking into how to compile it for Android. I don't know what I need to do to compile for Android. I couldn't find what to do for Android from Quazip's own instructions.

I am inexperienced in this matter and unfortunately this was the only post I came across on the forum about it.

GulsahAkt

@jsulm I managed to zip/unzip with quazip for Android device. With guidance from @jsulm. Thank you.
