QuaZip Import

VRonin

Instructions do not include the optional liblzma as it would need some testing on my part and I don't have MinGW on my pc atm.

install CMake if you don't have it already (https://cmake.org/)
install git if you don't have it already (https://git-scm.com/)
start a command prompt (cmd.exe), all the instructions beyond this point need to be run inside this cmd terminal
type cmake --version. if an error appears, call set PATH=path\to\cmake\bin;%PATH% where path/to/cmake/bin is the path to the bin folder of CMake (for me it's C:\Program Files\CMake\bin). Run cmake --version again to confirm no more errors
type git --version. if an error appears, call set PATH=path\to\git\bin;%PATH% where path/to/git/bin is the path to the bin folder of git(for me it's C:\Program Files\Git\bin). Run git --version again to confirm no more errors
cd into the bin folder of Qt (for me it's C:\Qt\5.15.0\msvc2019_64\bin)
call qtenv2.bat
cd into an empty folder and run these commands:

set CMAKEGENERATOR="MinGW Makefiles"
git clone --depth=1 https://gitlab.com/federicomenaquintero/bzip2.git bzip2src
cd .\bzip2src
mkdir .\build 
cd .\build
cmake -G %CMAKEGENERATOR% -DENABLE_LIB_ONLY=ON -DCMAKE_BUILD_TYPE="Release" -DCMAKE_INSTALL_PREFIX=../../bzip2 ../
cmake --build . --config Release
cmake --build . --target install --config Release
cd ..\..\
rmdir /Q /S bzip2src
set PATH=%CD%\bzip2;%PATH%
git clone --depth=1 https://github.com/madler/zlib.git zlibBuild
cd zlibBuild
mkdir .\build
cd .\build
cmake -G %CMAKEGENERATOR% -DCMAKE_INSTALL_PREFIX=../../zlib -DCMAKE_BUILD_TYPE=RELEASE ../
cmake --build .
cmake --build . --target install
cd ..\..\
rmdir /Q /S zlibBuild
set PATH=%CD%\zlib;%PATH%
git clone --depth=1 git://anongit.kde.org/extra-cmake-modules ECM
cd ECM
mkdir .\build 
cd .\build
cmake -G %CMAKEGENERATOR% -DBUILD_TESTING=OFF -DCMAKE_INSTALL_PREFIX=../../ECMbuild -DCMAKE_BUILD_TYPE=RELEASE ../
cmake --build .
cmake --build . --target install
cd ..\..\
set PATH=%CD%\ECMbuild;%PATH%
git clone --depth=1 git://anongit.kde.org/karchive.git KArchive
cd KArchive
mkdir .\build 
cd .\build
cmake -G %CMAKEGENERATOR% -DBUILD_TESTING=OFF -DCMAKE_DEBUG_POSTFIX=d -DCMAKE_INSTALL_PREFIX=../../KDEAPI -DCMAKE_BUILD_TYPE=DEBUG ../
cmake --build .
cmake --build . --target install
cmake -G %CMAKEGENERATOR% -DBUILD_TESTING=OFF -DCMAKE_INSTALL_PREFIX=../../KDEAPI -DCMAKE_BUILD_TYPE=RELEASE ../
cmake --build .
cmake --build . --target install
cd ..\..\
rmdir /Q /S ECMbuild
rmdir /Q /S ECM
rmdir /Q /S KArchive

Now you should have 3 folders. KDEAPI will contain the KArchive to link to it in Qt Creator the other 2 will contain the dlls required by KArchive to function

@VRonin Big thanks to you! I'm currently stuck at this:
... but I'll write to you when I have progress. Thanks bud!

FluentCoding

@VRonin I got an error.

... in this step: cmake -G %CMAKEGENERATOR% -DBUILD_TESTING=OFF -DCMAKE_DEBUG_POSTFIX=d -DCMAKE_INSTALL_PREFIX=../../KDEAPI -DCMAKE_BUILD_TYPE=DEBUG ../ (one of the last ones).

Should I update the config file?

VRonin

KArchive requires Qt 5.12 or newer, you have Qt 5.6 installed so it's not enough

FluentCoding

@VRonin I have the (almost) newest version installed :/ weird...

VRonin

After the "call qtenv2.bat" step, try calling qmake --version to check what Qt version you are using

FluentCoding

@VRonin

VRonin

and it still fails? very strange.
After calling qtenv2.bat could you type echo %PATH% and tell us what it prints?

FluentCoding

@VRonin

VRonin

wow, that's a messy PATH, you have more than 3 versions of mingw and apparently 2 of Qt in there.
before set CMAKEGENERATOR="MinGW Makefiles" run set PATH=C:\Program Files\CMake\bin;C:\Program Files\Git\cmd.

This hould get rid of the junk in there but you should really think about cleaning up that variable permanently from the variable editor removing stuff you don't need.

FluentCoding

@VRonin

Didn't work, even when setting QtCore_DIR ...

VRonin

did you run qtenv2.bat? can you tell us what echo %PATH% prints just before calling KArchive's CMake?

FluentCoding

@VRonin

VRonin

ok, let's start from scratch:
Now I know where you installed stuff so I can do it all in one script.
Open a new cmd window and run the following comands:

set PATH=C:\Program Files\CMake\bin;C:\Program Files\Git\cmd
set CMAKEGENERATOR="MinGW Makefiles"
cd /D D:\dev\Qt\5.14.2\mingw73_64\bin
qtenv2.bat
cd /D C:\Users\einst\Desktop
rmdir /Q /S KArchive
mkdir KArchive
cd KArchive
git clone --depth=1 https://gitlab.com/federicomenaquintero/bzip2.git bzip2src
cd .\bzip2src
mkdir .\build 
cd .\build
cmake -G %CMAKEGENERATOR% -DENABLE_LIB_ONLY=ON -DCMAKE_BUILD_TYPE="Release" -DCMAKE_INSTALL_PREFIX=../../bzip2 ../
cmake --build . --config Release
cmake --build . --target install --config Release
cd ..\..\
rmdir /Q /S bzip2src
set PATH=%CD%\bzip2;%PATH%
git clone --depth=1 https://github.com/madler/zlib.git zlibBuild
cd zlibBuild
mkdir .\build
cd .\build
cmake -G %CMAKEGENERATOR% -DCMAKE_INSTALL_PREFIX=../../zlib -DCMAKE_BUILD_TYPE=RELEASE ../
cmake --build .
cmake --build . --target install
cd ..\..\
rmdir /Q /S zlibBuild
set PATH=%CD%\zlib;%PATH%
git clone --depth=1 git://anongit.kde.org/extra-cmake-modules ECM
cd ECM
mkdir .\build 
cd .\build
cmake -G %CMAKEGENERATOR% -DBUILD_TESTING=OFF -DCMAKE_INSTALL_PREFIX=../../ECMbuild -DCMAKE_BUILD_TYPE=RELEASE ../
cmake --build .
cmake --build . --target install
cd ..\..\
set PATH=%CD%\ECMbuild;%PATH%
git clone --depth=1 git://anongit.kde.org/karchive.git KArchive
cd KArchive
mkdir .\build 
cd .\build
cmake -G %CMAKEGENERATOR% -DBUILD_TESTING=OFF -DCMAKE_DEBUG_POSTFIX=d -DCMAKE_INSTALL_PREFIX=../../KDEAPI -DCMAKE_BUILD_TYPE=DEBUG ../
cmake --build .
cmake --build . --target install
cmake -G %CMAKEGENERATOR% -DBUILD_TESTING=OFF -DCMAKE_INSTALL_PREFIX=../../KDEAPI -DCMAKE_BUILD_TYPE=RELEASE ../
cmake --build .
cmake --build . --target install
cd ..\..\
rmdir /Q /S ECMbuild
rmdir /Q /S ECM
rmdir /Q /S KArchive

@VRonin Nah, I'm giving up tbh. I get errors and erros and even then, is it worth it? I mean I just want to download a zip from my application and extract it from memory, but it wouldnt be so hard for the computer that it saves the zip into local storage and then extracts it from there. Also, I have an ETA for my application that I set myself. :/ But thank you so much for your help! I owe you..
