Implement something like tar archive in windows environment
-
-
@VRonin Hi, I have tried to add karchive libraries that I have downloaded from your link, but with out any success. I have used this link as a tutorial https://stackoverflow.com/questions/35008426/link-3rd-party-library-in-visual-studio .
When I try to compile my project I get the error: Cannot open include file: qplatformdefs.h: no such file or directory. -
@Zgembo said in Implement something like tar archive in windows environment:
qplatformdefs.h
That's an additional include.
In Project > Properties > C/C++->General > Additional Include Directories
Click Edit, and enter the path to the directory where the file "qplatformdefs.h" is locatedIt is in the mkspecs folder of qt, something like:
C:\Qt\5.12\msvc2015_64\mkspecs\win32-msvc
-
@VRonin it compiles. Now I have to find some examples of how to use just KArchive to create archive file without any compression.
-
from KArchive\examples\tarlocalfiles

If you want to compress it see
KArchive\examples\bzip2gzip
-
@VRonin Thank you for the example. I do not need to compress files. I just need to group few files to single archive (no compression) and to move it to another pc.
-
@Zgembo Take a look at documentation: https://api.kde.org/frameworks/karchive/html/classKTar.html
Especially "A class for reading / writing (optionally compressed) tar archives." -

Especially "A class for reading / writing (optionally compressed) tar archives."Thank you for your replay. I am really stuck with this. I have examined this example https://github.com/KDE/karchive/blob/master/examples/tarlocalfiles/main.cpp but when I run this program it asks for bzip2.dll and two more.
I really do not need to compress files. There is no example of using just KTar without compression. -
KTar allows you to read and write tar archives, including those that are compressed using gzip, bzip2 or xz.
You may not need to use compression, but that indicates that because the code supports compression you still need to provide the extra DLLs it is asking for. Their code will not get used in your case, but they still need to be present at runtime.

This is because KArchive can do much more than tar and my pre-compiled version allows you to do that linking to those libraries. They are available in the same link from which you downloaded the KArchive library.
Linking to those libraries does not mean your tar archive is getting compressed. it just means you have the option to compress it -

I have managed to create, test and run my test program in qt creator. I have managed to create a tar archive. Now I am trying to figure out how to unpack this archive file from my program.

That library uses the same interface for all "archives" so you can use the unzip example to extract your tar archive just by changing
KZip
toKTar

Thank you. Figured it out already :-)

I have moved my project from Qt Creator to Visual studio. I can compile the project in debug mode, but when I run it I get an error
"The application was unable to start correctly (0xc000007b). Click OK to close the application"I have added lib path to Project->Properties->Linker->Additional library directories
and I have added all required dll files to Linker->Input section (bzip2.lib, liblzma.lib, zlib.lib, KF5Archive.lib, KF5Archived.lib)I have added include path to Project->Properties->C/C++/General->Additional include directories
-
That error usually comes up when you mix 32 and 64 bits version of the libraries.
-
@VRonin Yes you are right. I have copied wrong dll to debug folder, so on runtime my app tried to open these 32-bit dlls.
Where is the best way to put these .dlls for production enviroment? Should I copy all these dlls to c:\windows\system32? -
@Zgembo said in Implement something like tar archive in windows environment:
Should I copy all these dlls to c:\windows\system32
Please not! :-)
Just put them in same directory where you have your executable. -
@jsulm OK, thank you. What about my include files? Now I have my KArchive folder that have "include" and "libs" subfolders in my C:\Downloads folder. I have included this two folders with their absolute path into my project (visual studio project).
Is there a better way to do this, because this is a large project that have a lot of developers. -

Every project will have its own convention. just ask how you guys handle 3rd party libraries locations
-
OK, thank you. My test program now works in debug mode. I am having problems compiling program in RELEASE mode. For some reason it can not see qplatformdefs.h . I have double checked that path to that file is included as @VRonin stated in some of the previous posts.
