How to use --extract on Linux-32 ? What extract archive mean?

[K-Rex]

I want to use -c -l to scan, but it scan all the files like .c .h and all, I don't want to scan .svn/ directory. How can I do?

I use : ./scancode -e ../gpl/
I get this error:

Extracting archives...

There is no libarchive.so in that directory!!!
Can anyone help me? Thx...

@K-Rex first, the pre-built binaries have not been built for 32-bites Linux... Do you have access to a 64 bits Linux installation instead?

I created a new ticket to ignore .svn dirs and similar ass #34

[pombredanne]

@K-Rex which exact Linux distro do you run?

[K-Rex]

My Linux environment is : Ubuntu 12.04 i386 GNU/Linux.

Can you tell me what -e command do?

I try to use it on WIN7 64bit. It generate housekeeper.a-extract directory (included file and platform_conf.o)

But I can't understand what it do. Thx

[pombredanne]

@K-Rex Thanks for the Linux version info.

The -e or --extract option looks in the input directory and extracts any archive or compressed files found there, such as a zip file, a tarball (or in your example a static library ar archive).

In your example above, housekeeper.a is an archive, so scancode -e extracted
the housekeeper.a archive to the housekeeper.a-extract directory where you can find the files that are contained in the original housekeeper.a archive, such as platform_conf.o and posssibly other files.

If you do not have archives in the directory you want to scan or you would prefer to extract these by hand before a scan, you do not need the -e/--extract option.

@K-Rex see also scancode --examples for --extract usage examples such as:

Extract all archives found in the 'samples' directory tree:

    scancode --extract samples

Note: If an archive contains other archives, all contained archives will be
extracted recursively. Extraction is done directly in the 'samples' directory,
side-by-side with each archive. Files are extracted in a directory named after
the archive with an '-extract' suffix added to its name, created side-by-side
with the corresponding archive file.

Extract a single archive. Files are extracted in the directory
'samples/arch/zlib.tar.gz-extract/':

    scancode --extract samples/arch/zlib.tar.gz

@K-Rex the new https://github.com/nexB/scancode-toolkit/releases/tag/v1.3.0 has experimental binaries for Linux 32 bits and improved help for the --extract option. I will make this an official release when I have you testing feedback

[K-Rex]

I download "scancode-toolkit-1.3.0.tar.bz2" and install it, but it still can't work for Linux 32 bits.

error:
ImportError: Failed to load libarchive: '/home/rex/qdu_claro/yuki/tools/scancode-toolkit-1.3.0/src/extractcode/bin/linux-32/bin/libarchive.so'
