Package: extract
Version: 1:0.6.3-4
Severity: important
Tags: upstream patch
Dear Maintainer,
The extract command is currently unusable in Debian amd64.
Every plugin loaded fails with this sort of error message:
>Resolving symbol
>`EXTRACTOR_64-linux-gnu/libextractor/libextractor_elf_extract' failed,
>so I tried `_EXTRACTOR_64-linux-gnu/libextractor/libextractor_elf_extract',
>but that failed also.
>Errors are: `/usr/lib/x86_64-linux-gnu/libextractor/libextractor_elf.so:
>undefined symbol:
>EXTRACTOR_64-linux-gnu/libextractor/libextractor_elf_extract' and
>`/usr/lib/x86_64-linux-gnu/libextractor/libextractor_elf.so: undefined symbol:
>_EXTRACTOR_64-linux-gnu/libextractor/libextractor_elf_extract'.
>Resolving `extract' method of plugin `elf' failed: (null)
>Plugin `elf' failed to load!
The plugins are stored in /usr/lib/x86_64-linux-gnu/libextractor/ on my system.
The program parses the .so name to derive the extract function symbol name,
and is confused by the _ in the lib path.
I have modified the source to search for the last _ in the .so filename instead
of the first.
The first patch is against Debian's 0.6.3-4 as retrieved by apt-get source.
The second patch is against upstream HEAD (currently rev21634) which has
re-arranged the code a bit.
These patches are untested as I am having trouble building a working binary
(vanilla or modified) but as you can see the changes are fairly minor.
Regards,
Harun Trefry
