A fork ofSevenZip++ for modern builds. Uses cmake to generate build files for desired Visual Studio version, seesetup section for instructions.

Uses latest lzma1801 SDK

Originally from:http://bitbucket.org/cmcnab/sevenzip/wiki/Home

This is a C++ wrapper for accessing the 7-zip COM-like API in 7z.dll and 7za.dll. This code is heavily based off of the Client7z sample found in theLZMA SDK.

The project itself is a static library.

To use, first load the 7z DLL into memory:

#include<7zpp/7zpp.h>SevenZip::SevenZipLibrary lib;lib.Load();

If the appropriate 7z DLL is not in your path you may wish to specify it explicitly in the call to load. Note you may have the 64-bit version installed but are trying to load it from a 32-bit executable; keep that in mind if you encounter errors.

lib.Load(_T("path\\to\\7za.dll"));

Then create and use a compressor:

SevenZip::SevenZipCompressorcompressor(lib, archiveName);compressor.SetCompressionFormat(SevenZip::CompressionFormat::Zip);compressor.UseAbsolutePaths(false);compressor.AddFile(targetFile);compressor.AddDirectory(targetDir);compressor.DoCompress(callbackfunc);

Or an extractor:

SevenZip::SevenZipExtractorextractor(lib, archiveName);// Try to detect compression typeif (!extractor.DetectCompressionFormat()){extractor.SetCompressionFormat(SevenZip::CompressionFormat::Zip);}...// Change this function to suitSevenZip::ProgressCallBack *extractcallbackfunc =nullptr;...extractor.ExtractArchive(destination, extractcallbackfunc);

Or a lister:

classListCallBackOutput : SevenZip::ListCallback{virtualvoidOnFileFound(WCHAR* path, ULONGLONG size){std::wcout<< path<<L""<< size<< std::endl;}};...SevenZip::SevenZipListerlister(lib, archiveName);// Try to detect compression typeif (!lister.DetectCompressionFormat()){lister.SetCompressionFormat(SevenZip::CompressionFormat::Zip);}ListCallBackOutput myListCallBack;lister.ListArchive((SevenZip::ListCallback *)&myListCallBack);

Note: Most of the functions now return a boolean to indicate if it workedinstead of throwing an exception.

Otherwise, don't forget to wrap the operations in a try/catch block to handle errors:

...catch (SevenZip::SevenZipException& ex){    std::cerr << ex.GetMessage() << std::endl;}...

1. Ensure you havecmake andgit installed. Navigate to folder of choice.
2. Open a powershell window and typegit clone https://github.com/getnamo/7zip-cpp.git --recursive
3. Navigate into the newly cloned projectcd 7zip-cpp
4. (Optional for Test app only) Download and buildBoost
5. Example build with cmake using powershell

cd buildcmake -G "Visual Studio 15 2017 Win64" ../cmake --build ../build --config Release

6. Commands from 5 will build win64 Release target and output will be found inbuild/Release/7zpp.lib

Add project into your cmakelists

add_subdirectory(${pathto7zip-cpp} ${PROJECT_SOURCE_DIR}/build/build7zpp)target_include_directories(${my_project} INTERFACE ${pathto7zip-cpp}/Include)target_link_libraries(${my_project} 7zpp)add_dependencies(${my_project}  7zpp) #might not be necessary

In order to compile the tests,you must have boost libraries in your path or specify the location where cmake can find them

1. Assuming you're in the project directory
2. Download and buildBoost

cd buildcmake ../ -DBOOST_ROOT="My boost location"

2. Then finallycmake --build ../build to build

Only 1 test unit is failing.
