ar-cpp

Warning: This project was an experiment and is no longer maintained. I suggest using a different library.

A C++ library for parsing of ar archives.

#include <ar/ar.h>

auto files = ar::extract(ar::File::fromFilesystem("/path/to/archive.a"));
for (auto& file : files) {
    std::cout << file->getName() << "\n";
    file->saveCopyTo("/path/to/directory");
}

Status

The library currently supports basic extraction of GNU/System V archives.

Requirements

To build the library, you need:

  • A compiler supporting C++14, such as GCC version >= 4.9, Clang version >= 3.4, or Visual Studio 2015 or greater.
  • CMake version >= 3.5.

The library is developed and tested on Linux, although it should also work on Windows (Visual Studio 2015 or greater), and possibly on macOS as well. If not, please, submit an issue.

Build and Installation

  • Clone the repository or download the sources into a directory. Let's call that directory ar-cpp.
  • cd ar-cpp
  • mkdir build && cd build
  • cmake ..
  • Linux: make and make install
  • Windows: Open the generated ar.sln project file in Visual Studio and build it from there.

You can pass additional parameters to cmake:

  • -DAR_DOC=ON to build with API documentation (requires Doxygen, disabled by default).
  • -DAR_TOOLS=ON to build with tools (disabled by default).
  • -DAR_TESTS=ON to build with tests (requires GoogleTest, disabled by default).
  • -DAR_COVERAGE=ON to build with code coverage support (requires GCC and 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=ar-install-dir to set a custom installation path.
  • -G to set a custom project files generator (the default one generates UNIX Makefiles). For example, for Visual Studio 2015 on 64b Windows, use -G"Visual Studio 14 2015 Win64".

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.

Use

After the installation, you can incorporate the library into your project in the following way (provided that you use CMake):

find_package(ar)

add_executable(your_app your_app.cpp)
target_link_libraries(your_app ar)

If you have not installed ar-cpp into your system (i.e. you installed it only locally into some directory), you will have to provide the path to the $INSTALL_DIR/lib/cmake/ar directory prior to calling find_package(ar), either by

set(ar_DIR "$INSTALL_DIR/lib/cmake/ar")

or via the following cmake parameter:

-Dar_DIR "$INSTALL_DIR/lib/cmake/ar"
