README

        
Faulty.lib is a dynamic linker with the ability to load libraries

from Zip archives. At the moment, it only works on ELF Linux systems.

You can build it with the following commands:

  autoreconf

  ./configure

  make

Automated tests can be run with `make check'.

The result of a build is a static library that provides __wrap_dlopen,

__wrap_dlerror, __wrap_dlsym, __wrap_dlclose, __wrap_dladdr functions

with the same prototypes as the dl* family of functions.

Loading a library from a Zip archive is achieved by passing a specially

crafted path name to __wrap_dlopen.

Its form is `/path/to/file.zip!/subdir/library.so'.

On-demand decompression of the libraries is also possible if, instead

of being normally zipped, they are first "szipped", then stored in the

Zip archive. So, instead of doing the following to put a library in the

Zip archive:

  zip file.zip library.so

you first need to use the "szip" tool from the linker/ directory:

  linker/szip library.so library.so.new && mv library.so.new library.so

and store the resulting file in the zip:

  zip -0 file.zip library.so

The library may then be loaded with the same path form as if it were

normally compressed.
