linoodle

A Linux wrapper for the Oodle Data Compression library.

It essentially works like this:

1. Parse the Windows Oodle DLL in the current directory (oo2core_8_win64.dll) using the pe-parse library
2. Map the PE into memory
3. Perform relocations
4. Resolve imports to point to our own implementation of the minimum set of required Windows API functions
5. Setup the gs register to point to a fake TIB structure
6. Execute the DLL's entry point
7. Execute whatever Oodle exports you want (currently only OodleLZ_Decompress)

Usage

When you clone this repository, make sure you use --recurse-submodules to get the pe-parse submodule. Otherwise you can run git submodule update --init after you've cloned it.

After that, just use cmake to build the project and you'll get a liblinoodle.so file created in the build directory. You can link to this or use dlopen, then call the OodleLZ_Decompress export.

mkdir build
cd build
cmake ..
cd ..
cmake --build build/

This will also build an executable which tests that the library works. Run it with ./build/testlinoodle.
