Ways to Reproduce the issue (optional):

[Alvazz]

[Alvazz]

When I build the QArchive Examples, also got this error.

MSVC 2022, Qt6.5.1

[antony-jr]

@Alvazz is libarchive installed properly? it seems like it's trying to link to libarchive but can't find it. To install libarchive, download prebuilt libarchive for msvc and copy paste the libs to the Qt folder. (Note if you use prebuilts, then see if it's debug build or release build, if it's release build then you have to build your project in release mode also)

[antony-jr]

@Alvazz can you try an experimental fix? (I have been meaning to make QArchive install easily in windows). Follow the below steps, (This only works for msvc2019_64 kit, make sure you are using that, select it in QtCreator)

• Go to C:\Qt or the directory where you installed Qt under Windows
• Open "Maintenancetool.exe", create a account and continue, now you will see add or remove components.
• Before clicking on Next, click on the settings icon on the bottom left corner.
• Now go to "Repositories" tab and add a user defined repository with the following url,

 https://qt.antonyjr.in/qt5_15_2/windows/

• Now click on Ok and the maintenance tool will restart
• Now continue into Add or Remove Components
• Now you will see "QArchive (Windows MSVC)" under the list box
• Select that, make sure you are using msvc2019_64 kit and have Qt 5.15.2 or above (not Qt 6 though)
• Click on Next
• Click Update and Confirm License
• Finish

No restart your QtCreator, open your project, simply add find_package(QArchive) to your Cmake file and try to build your app, it should build. Make sure you use Release mode, since the prebuilt binaries are only meant for Release build type.

[Alvazz]

OK, I'm traveling these days, I'll try it later

[antony-jr]

OK, I'm traveling these days, I'll try it later

no problem, try whenever you have time, I will release a detailed documentation on this method soon. Thanks.

Could alternatively try meson. libarchive is available as a subproject.

Could alternatively try meson. libarchive is available as a subproject.

I think pre-built libraries are much easier for windows users, but meson is much better for *nix users. Well it's the choice of the user, need more documentation for using meson under Windows with MSVC. With the new prebuilts, the user don't even need to care about compiling libarchive or QArchive. I think that's a good thing. For now I'm using Conan to build prebuilts for windows but zstd tests are failing for some reason, maybe we need to build using Meson, I tried but I'm lacking knowledge to compile with MSVC with meson (windows tests has some pointers but it uses msys)

[neheb]

Maybe @eli-schwartz has more info. I don’t really use MSVC.

maybe we need to build using Meson, I tried but I'm lacking knowledge to compile with MSVC with meson (windows tests has some pointers but it uses msys)

Not entirely sure I understand what the snag here is, but in general, Meson and MSVC should be more or less out of the box.

• if you run meson from a MSVC dev command prompt, meson simply uses MSVC
• if you run meson setup --vsenv meson simply uses MSVC
• if you run meson and MSVC is the only compiler available, meson uses MSVC
• if you run meson and MSVC is not set up, but you have mingw GCC (e.g. msys2) set up and in your path, meson uses GCC

* if you run `meson setup --vsenv` meson simply uses MSVC

* if you run meson and MSVC is _not_ set up, but you have mingw GCC (e.g. msys2) set up and in your path, meson uses GCC

Thanks for the info, It's not that I don't understand meson, its simply because I could not figure out how to build and install the binaries into a directory to package it to the users to use it as prebuilt library (this is clearly a skill issue, will have to read more docs), thanks for chiming in.
