Installing YAP {#install} ++++++++

Downloading YAP

The latest development version of Yap-6 is available source-only through GIT repositories. The main reference repository is at

We store an older version of YAP at:

Please just use git clone to obtain the distribution. Ie, to download YAP from the command line please type:

git clone https://github.com/vscosta/yap-6.3 yap-6.3

The first argument is the repository, the last argument is the (optional) target directory.

There are a variety of graphical interfaces to git, including GitHub's own GitHub Desktop that supports Microsoft Windows and Apple OSX. A list with GUI applications, editor integration, and much more can be found at the git Wiki,

Download Options

It may be useful to know:

  • If you are have limited bandwith or disk spaceq, consider using git clone --depth XX to only include the last XX commits.

  • Older versions of YAP were distributed with modules. YAP-6.3.5 is a single package, and it does not need git submodule.

  • The GitHub site includes a number of companion packages for YAP, including doxygen-yap, a version of doxygen adapted to Prolog that was used to generate these documents.

Compiling YAP


YAP-6.3.4 is a cmake based system. We use cmake because it supports mosts popular software, can generate Makefiles, Ninja, Apple's XCode, VisualStudio and ANdroid Studio, and because it includes packaging suppport, The steps required to install core YAP under cmake:

C/C++ compiler

Status as of early 2017

YAP should compile well under the [GNU-CC](https://gcc.gnu.org/)
and the [C-LANG]https://clang.llvm.org/() families, that are
available across most configurations. It sshould also compile well
undder Intel `icc`.

We do not recommend using Microoft's VC++. To the best of our
knowledge MSC does not support threaded emulation, which YAP recquires
for performance, You can still use the IDE, and experiment with
the c-lang plugin.

YAP compiles cleanly under cross-compilers, and we have used the
crosss-compilation system [mxe](http://mxe.cc/) system with good results.
cmake

All Linux and BSD distributions include cmake, so does Homebrew and MacPorts for the Mac, and MSYS2 and cygwin for WIN32. Android Studio has native support for cmakesince 2.1, although we advise to use 2.2. Last, there are excellent plugins for the Visual Codes. In case you need a recent version, consider using pre-compiled binaries at the CMake site.

If you have an older Linux you may need to compile from source, available at GitHub.

Ensure that you have other necessary packages installed:
  • YAP requires [gmp]{https://gmplib.org/} for infinite precision integer and rational. Please ensure the development pacakage is installed in Linux: `(lib)gmp-dev(el). In the Mac and WIN32, you can obtain GMPlib from the pakage collections mentioned above.

    The [MPIR]{http://mpir.org} library is compatible with GMPlib,
    and has good support for VC++.
    
  • The readline library provides line-editing and command history. In Linux, make sure you have the development package.

    Readline is disabled by default in WIN32. OSX is distributed with a line editing library that includes a subset of readline. We advise against using that library.

  • To use YAP as a library in Python you need the SWIG interface generator and python3-dev. SWIG and Python binaries can be easily obtained for all these platfors

    • make sure to install Python-3, and not Python-2,
Compile and Install

1: Create a directory, say Build and cd to the directory (cd Build). *YAP should not be compiled at its rootxo directory, some packages do not allow for that.

2: Run cmake ../ from within Build (or equivalent)

3: Run make from within Build (or equivalent)

4: If the compilation succeeds, try ./yap. This is your executable.

5: If you feel satisfied with the result, do make install. * In most systems you will need to be superuser in order to do make install and make info on the standard directories.

Tuning the Functionality of YAP

By default, YAP supports tabling, depth first search, and most features found in modern Prologs. In some cases, you may want to suport extra features, or reduce system size. cmakeprovides an graphical interface for doing so. From the commmand line, a typical example could be:

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=~ /users/vsc/src/yap

The first argument says that this is a release, compiled with full optimisation. The second argument says YAP should install under the ~ drectory. In this case, YAP will add the binaries to /users/vsc/bin, include files to /users/vsc/include/Yap, Prolog files to /users/vsc/share/Yap, and ay DLL to /users/vsc/lib/Yap.

Options include:

  • CMAKE_BUILD_TYPE: the two main options are Debug, for system development, and Release. to use the system.

  • CMAKE_INSTALL_PREFIX: where to install YAP, by default /usr/local.

  • WITH_DEPTH_LIMIT allows depth limited evaluation, say for implementing iterative deepening (default)

  • WITH_CALL_TRACER allows support for tracing all calls, retries, and backtracks in the system. This can help in debugging your application, but results in performance loss (enabled in Debug).

  • WITH_WAM_PROFILER allows profiling of abstract machine instructions. This is useful when developing YAP, should not be so useful for normal users (not currently supportted)

  • WITH_YAP_CONDOR allows using the Condor system that support High Throughput Computing (HTC) on large collections of distributively owned computing resources (not yet available)

  • WITH_TABLING allows tabling support (default)

  • WITH_YAPOR_COPY allows or-parallelism according to the Muse-based, YapOR model. This option is still highly experimental.

  • WITH_GMP give a path to where one can find the GMP library if not installed in the default path. It is highly advised to have GMP in your compilation environment.

  • WITH_READLINE give a path to where one can find the readline library if not installed in the default path. It is highly advised in Unix-like environments but not useful in Windows.

  • -WITH_Threads allows using of the multi-threading predicates provided by YAP.

You may also want to use a different compilation environment. As an example:

cmake -GXcode ..

will generate files for compilation of YAP within Apple's Xcode IDE. You can also use xcodebuild from the command line.

Bext follow instructions to fully compile YAP:

Compilation Notes for OSX/Brew

Next follows a detailed description of a full install of YAP, including all the packages that YAP can use:

  1. Install the XCode toolkit from the Apple App Store (you may have to register as a developer).

  2. Install a package manager, such as brew,

  3. You will need cmake and gmp: both are available in brew.

  4. other brew packages you may want to install: gecode, libxml2, openssl, mariadb, openmpi, postgresql, raptor, sqlite3, swig, unixodbc. Note that some of them may be preconditions to other packages.

  5. to install cudd, a package used by ProbLog and cplint, just use:

brew tap mht208/formal
brew install cudd
  1. To use R, you must download the R distribution from one of the many R mirrors.

  2. To use Java, you should download the Oracle distributed JDK.

  3. When installing Python, verify which python you are using.

  4. There may be conflict between original OSX and the brew packages (eg, openssl, python, and sqlite3. If you prefer leaning on brew:

cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl ..

Compilation Notes for Android

Next we present the compilation process for Android. The environment is an OSX, but steps should be similar for Linux machines. We assume you have downloaded both the Android NDK and the Android SDK.

  1. Reserve a directory for compilation:
 mkdir android
 cd android
  1. Get the GMP-android port.

  2. Call cmake:

export ANDROID_NDK=/Volumes/Transcend/vsc/android-ndk-r11c; \
export ANDROID_SDK=/Volumes/Transcend/vsc/AndroidSDK;\
export ANDROID_PORT=1;\
export  PATH=$PATH:/Volumes/Transcend/vsc/AndroidSDK/tools/;\
cmake \
      -DGMP_INCLUDE_DIRS=/Users/vsc/github/gmp/armeabi-v7a \
      -DGMP_LIBRARIES=/Users/vsc/github/gmp/armeabi-v7a/libgmp.so\
      -DCMAKE_TOOLCHAIN_FILE=/users/vsc/github/yap-6.3/cmake/android.toolchain.cmake \
     -DANDROID_ABI=armeabi-v7a -DANDROID_NATIVE_API_LEVEL=android-23  \
     .. && make -j
