A C++ library and tools providing easy access to the retdec.com decompilation service through their public REST API.

The following example creates a decompiler, starts a decompilation of the given binary file, and prints the decompiled C code to the standard output.

#include <iostream>
#include <retdec/retdec.h>

using namespace retdec;

int main(int argc, char **argv) {
    if (argc != 3) {
        std::cerr << "usage: " << argv[0] << " API-KEY FILE\n";
        return 1;
    }

    try {
        Decompiler decompiler(
            Settings()
                .apiKey(argv[1])
        );
        auto decompilation = decompiler.runDecompilation(
            DecompilationArguments()
                .mode("bin")
                .inputFile(File::fromFilesystem(argv[2]))
        );
        decompilation->waitUntilFinished();
        std::cout << decompilation->getOutputHll();
        return 0;
    } catch (const Error &ex) {
        std::cerr << "error: " << ex.what() << "\n";
        return 1;
    }
}

The library currently provides basic support of the decompilation, file-analyzing, and test services.

To build the library and tools, you need:

• A compiler supporting C++14. Supported compilers are:
  • GCC (version >= 4.9)
  • Clang (version >= 3.5)
  • MS Visual Studio (version 2015)
• CMake (version >= 2.8)
• Boost (version >= 1.55)
• cpp-netlib (version >= 0.11)
• OpenSSL (version >= 1.0)
• JsonCpp (version >= 1.0)

The Boost and OpenSSL libraries have to be installed on your system. Other libraries are automatically downloaded and built if they are not present on your system.

• Clone the repository or download the sources into a directory. Lets call the directory retdec.
• cd retdec
• mkdir build && cd build
• cmake ..
• make && make install

You can pass additional parameters to cmake:

• -DRETDEC_DOC=1 to build with API documentation (requires Doxygen, disabled by default).
• -DRETDEC_TOOLS=1 to build with tools (disabled by default).
• -DRETDEC_TESTS=1 to build with unit tests (disabled by default).
• -DRETDEC_COVERAGE=1 to build with code coverage support (requires LCOV, disabled by default).
• -DCMAKE_BUILD_TYPE=Debug to build with debugging information, which is useful during development. By default, the library is built in the Release mode.
• -DCMAKE_INSTALL_PREFIX:PATH=/usr to set a custom installation path.

You can force a specific version of the required libraries by using the following cmake parameters:

• -DBOOST_ROOT=$BOOST_DIR
• -DCPPNETLIB_ROOT=$CPPNETLIB_DIR
• -DOPENSSL_ROOT_DIR=$OPENSSL_DIR
• -DJsonCpp_ROOT_DIR=$JSONCPP_DIR

The make call supports standard parameters, such as:

• -j N to build the library by using N processors.
• VERBOSE=1 to show verbose output when building the library.

If you use CMake, you can incorporate the library into your project in the following way:

set(retdec_DIR "/path/to/installed/retdec/lib/cmake")
find_package(retdec)
include_directories(SYSTEM ${retdec_INCLUDE_DIR})

add_executable(your_app your_app.cpp)
target_link_libraries(your_app retdec)

The API documentation is available here:

• latest
• 0.2
• 0.1

You can also generate it by yourself (pass -DRETDEC_DOC=1 to cmake and run make doc).
