A fork of SevenZip++ for modern builds. Uses cmake to generate build files for desired Visual Studio version, see setup 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 the LZMA 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::SevenZipCompressor compressor(lib, archiveName); compressor.SetCompressionFormat(SevenZip::CompressionFormat::Zip); compressor.UseAbsolutePaths(false); compressor.AddFile(targetFile); compressor.AddDirectory(targetDir); compressor.DoCompress(callbackfunc);
Or an extractor:
SevenZip::SevenZipExtractor extractor(lib, archiveName); // Try to detect compression type if (!extractor.DetectCompressionFormat()) { extractor.SetCompressionFormat(SevenZip::CompressionFormat::Zip); } ... // Change this function to suit SevenZip::ProgressCallBack *extractcallbackfunc = nullptr; ... extractor.ExtractArchive(destination, extractcallbackfunc);
Or a lister:
class ListCallBackOutput : SevenZip::ListCallback { virtual void OnFileFound(WCHAR* path, ULONGLONG size) { std::wcout << path << L" " << size << std::endl; } }; ... SevenZip::SevenZipLister lister(lib, archiveName); // Try to detect compression type if (!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 worked instead 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; } ...
- Ensure you have cmake and git installed. Navigate to folder of choice.
- Open a powershell window and type
git clone https://github.com/getnamo/7zip-cpp.git --recursive - Navigate into the newly cloned project
cd 7zip-cpp - (Optional for Test app only) Download and build Boost
- Example build with cmake using powershell
cd build
cmake -G "Visual Studio 15 2017 Win64" ../
cmake --build ../build --config Release
- Commands from 5 will build win64 Release target and output will be found in
build/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
- Assuming you're in the project directory
- Download and build Boost
cd build
cmake ../ -DBOOST_ROOT="My boost location"
- Then finally
cmake --build ../buildto build
Only 1 test unit is failing.
