Project ERROR: Unknown module(s) in QT: KArchive

Abdulmueez

After installing KArchive on my windows, I am still getting the error,

Project ERROR: Unknown module(s) in QT: KArchive

What should I do next please or what am I doing wrong?

Hi @abdulmueez,

how did you install the library?
have you checked that the include files, lib and dll files have been copied to your Qt installations respective directories?
on Windows, you need separate files for debug and release builds. Can you check the other build type and see if that works?

Regards

Installed it according to the instructions in the website https://wiki.qt.io/Karchive_on_windows
Do I have to manually include all the files, lib and dll and if yes, to which directories exactly?

Hi,

Can you share your .pro file ?

Did you check on your system for the presence of a KArchive.pri file ?

I found these 2 .pri files, Are they the ones ?

Abdulmueez

So, I found a possible solution that involves including the pri files in the pro file of my project,

include(C:/Users/emiol/OneDrive/Desktop/Git/kaarchive/build/src/qt_KArchive.pri)

These removes the above error, but I can't still make use of the headers(KZip,karchivedirectory,...), there files are not found.

I think the errors are from the pri files, the headers ain't included in it, Here is the content

QT.KArchive.VERSION = 5.61.0
QT.KArchive.MAJOR_VERSION = 5
QT.KArchive.MINOR_VERSION = 61
QT.KArchive.PATCH_VERSION = 0
QT.KArchive.name = KF5Archive
QT.KArchive.module = KF5Archive
QT.KArchive.defines = 
QT.KArchive.includes = C:-DCMAKE_BUILD_TYPE=release/include/KF5/KArchive
QT.KArchive.private_includes =
QT.KArchive.libs = C:-DCMAKE_BUILD_TYPE=release/lib
QT.KArchive.depends = core

SGaist

Did you call make install after building the module ?

Abdulmueez

Yes, I did that

Abdulmueez

So, I manually added the files and I have this,
I'm not sure I did the right thing, Is the format of the pri file correct now?
This doesn't solve the error though, I just want to know whether I'm thinking in the right direction?

Building KArchive on windows is not trivial and that article is badly out of date.
You can download a pre-built version for MSVC2017 from here (expires in 6 months):

32bit
64bit

Then unpack it and add the below to your project (.pro) file (this assumes you uncompressed the library in C:\KDE)

LIBS += -LC:/KDE/lib
INCLUDEPATH +=  C:/KDE/include/KF5/KArchive
CONFIG(release, debug|release) {
LIBS += -lKF5Archive
}
CONFIG(debug, debug|release) {
LIBS += -lKF5Archived
}

Thanks a lot, It works fine now.
I really appreciate all thehelp
