lib7zip's Introduction

lib7zip

A library using 7z.dll/7z.so(from 7-Zip) to handle different archive types. lib7zip is based on 7zip/p7zip source code, but NOT including any source code from 7zip/p7zip.

Tips

Build lib7zip
- Under UNIX/LINUX like system
  - Get a copy of p7zip source code, and extract to a folder
  - Define a env P7ZIP_SOURCE_DIR point to the extracted folder
  - cmake -DBUILD_SHARED_LIB=OFF -DP7ZIP_SOURCE_DIR=${P7ZIP_SOURCE_DIR}
- Under windows
  - Get mingw from http://www.mingw.org
  - Get a copy of original 7zip source code, NOT the p7zip for linux
  - Define a env P7ZIP_SOURCE_DIR point to the extracted folder
  - cmake -DBUILD_SHARED_LIB=OFF -DP7ZIP_SOURCE_DIR=${P7ZIP_SOURCE_DIR}
Run lib7zip
- Under UNIX/LINUX like system
  - install p7zip binary
  - find 7z.so path, export LD_LIBRARY_PATH=<where 7z.so existing>
- Under Windows
  - install 7zip binary
  - copy 7z.dll to where your application existing

The sample file is in
memory_leak.zip
860e4e7d205b6a483ed12569fbcb9cf0

and use 7z to extract this file has no memory leak

failed to extract the rar file

I failed to extract the rar file using Test7Zip/Test7ZipRar5.cpp on Linux. It can create new files but not write bytes. I am using p7zip_16.02.

I successfully created the bin/7z.so library in the p7zip project by running make 7z.
After that I built lib7zip sources by cmake -DBUILD_SHARED_LIB=OFF -DP7ZIP_SOURCE_DIR=/xxx/p7zip_16.02
What do I do now?
I want to build and run Test7Zip.cpp as a portable executable.

lib7zip is thread-safe or not?

i had tried multi thread with lib7zip.But unfortunatly got a error core dump

how to package / unpackage files by lib7zip?

Hi there, thanks for this lib7zip. Is there any sample codes about how to package files to a .zip file and how to unpackage files from a .zip file?

how to run the code?

Not able to run the code on my local machine.
Can you please help with a step-by-step procedure to run the code on my machine. I am using Ubuntu 14.04 LTS

After the multi-volume decompression is completed, the test.7z.001 file cannot be deleted

Hi ！

After the multi-volume decompression is completed, the test.7z.001 file cannot be deleted

Does it can uncompress .DOC Format?

i know 7z can support many format, so i need it to uncompress DOC, Does it can uncompress .DOC Format?

Memory leak?

Hi,
I'm opening an archive and then closing it, and when running the application in valgrind it reports this:

When using file signature to ID file types, ran into a collision which mis-identified a file type.

I had a multifile RAR set that refused to decode. It failed while opening the first archive. I troubleshot it down to where it picked which codec to use. It found a "BD" in the data for a two character signature and then picked the wrong codec which failed to open the archive.

I changed the code to require that both the signature and extension match. It works but it defeats the purpose of using signature only. My suggestion is sort the signatures in "length of signature" order so the long signatures get checked before the short signatures. Every byte of additional signature that matches increases the confidence in the signature match.

Compilation Fails on Linux

Getting this error on linux:

7ZipArchive.cpp:8:34: fatal error: CPP/myWindows/StdAfx.h: No such file or directory
 #include "CPP/myWindows/StdAfx.h"

...can't figure out what flags to set to tell make that I'm not on WIN32

Test7Zip.cpp - how to extract multiple files from the archive?

I see, the Test7Zip.cpp extracts 1 file from the archive. Is there any example that shows how to extract multiple files from an archive?
