Quazip-1.3 static linking issue

VRonin

Seems like you forgot to install QuaZip...

add -DCMAKE_INSTALL_PREFIX="C:/ZipDev/QuaZip" to the first cmake call (the configuration) and, after the build, call cmake --build C:/ZipDev/quazip-1.3/msvc2019/static/x86/debug --config Debug --target install. You will now have the Quazip library installed in C:/ZipDev/QuaZip that you can reference in your .pro file

I have tried your solution but it still leads to these linking errors.

.pro file:

unresolved external symbol "__declspec(dllimport)

Seems like it's trying to link QuaZip dinamically, ignoring DEFINES += QUAZIP_STATIC

What's the content of C:/ZipDev/QuaZip and its subfolders now?

Cobra91151

@VRonin

Yes, I think it ignores the DEFINES += QUAZIP_STATIC and links to dynamic libs for some reason.

The content of C:/ZipDev/QuaZip folder: QuaZip content.gif

Looks good.

#include "JlCompress.h"

Did you try to unpack QuaZip directly in your source code? Do you have another instance of JlCompress.h in your source tree? If so delete it and also change it to #include <JlCompress.h> just in case

Cobra91151

@VRonin

No, my project source code is available: C:\Users\cobra\Documents\Projects\CPP\QuaZipTest
QuaZip is installed: C:\ZipDev\QuaZip
I have only 1 instance of JlCompress in the source tree, please check out the following screenshot:

I changed to <JlCompress.h> but it still displays these errors.

I have an idea. When selecting cmake compiler: -G "Visual Studio 16 2019" -A "Win32"

It produces the following output:

-- Selecting Windows SDK version 10.0.22000.0 to target Windows 10.0.19044.
-- The C compiler identification is MSVC 19.29.30143.0
-- The CXX compiler identification is MSVC 19.29.30143.0

So, I will try to build it using VS 2022: -G "Visual Studio 17 2022" -A "Win32" to check for such issues.

No, that's a mess, please revert.

When selecting cmake compiler: -G "Visual Studio 16 2019" -A "Win32"

I wouldn't bother, just use -G"NMake Makefiles", it's a bit slower but QuaZip is not a big project and that will automatically select the compiler you are using and you won't even need to specify --config Debug.

In any case, this does not seem like a problem in the QuaZip build side. The library is installed correctly so that side worked, the problem is in your program using it. Can you try with a brand new project?

Cobra91151

@VRonin

I know, it is the mess. That's why I always linking instead of unpacking everything to the source. Actually, this is the brand new project which I have created to test Quazip because in my real project it leads to the same issues. Previously, I have used the quazip-0.9.1 and it worked without issue. This issue is only with Quazip-1.3. I do not think it is related to the program. I think, something is wrong with Quazip static library. Anyway, I will try my and your solution: -G"NMake Makefiles" and reply soon.

Cobra91151

@VRonin

I have tried both solutions with VS 2022 and NMake Makefiles, but it still displays these linking errors. So, I have found this old article: https://forum.qt.io/topic/8492/solved-cannot-get-quazip-test-to-work/2, it maked as solved but I can not find the actual post with a solution. Any ideas?

Cobra91151

@VRonin

QuaZip VS solution uses by default: Use Multi-Byte Character Set and it could be changed to: Use Unicode Character Set or Not Set.
When I try to add my test project using VS 2019 -> Qt extension, it displays the charset as: Not Set.
So, I think it could be Use Unicode Character Set or better to set the Not Set option for this QuaZip static library when building QuaZip lib.

Cobra91151

@VRonin

No, it does not work. I have tried a lot of different solutions but it still fails with linking issues. This is the library issue. So, I do not have any options left but to drop QuaZip and create my own library.

@Cobra91151 said in Quazip-1.3 static linking issue:

drop QuaZip and create my own library

That's a giant leap.

try compilying it dinamically and use it as a dll, why not
consider alternatives, like KArchive

Cobra91151

@VRonin

Using DLL is not an option in my case because it must be only .exe file for installer. I do not think KArchive is worth trying since it could be the same issue at some point. I prefer code it by my own and have a full control over it. Simple lib to zip/unzip archives wrapper for Qt. Thanks.

Cobra91151

Hello!

I have created my own CZip library which adds content to archive and extracts it.
The issue is resolved.
