Downloading and Installing YAP

This text includes instructions to download and install YAP.

[TOC]

@section Download 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,

@subsection DownloadOptions 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.

@section CompilingYAP 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 are presented in detail next.

@subsection Compilation The compiler: Status as of early 2017

YAP should compile well under the GNU-CC and the C-LANG 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 system with good results.

@subsection cmake 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.

@subsection extrapacks 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,

@subsection Compiling2 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.

@subsection TuningYAP 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:

@subsection TuningBrew 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](http://brew.sh),

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](http://vlsi.colorado.edu/~fabio/CUDD), a package used by ProbLog and cplint, just use:
brew tap mht208/formal
brew install cudd
6. To use [R](https://www.r-project.org), you must download the `R` distribution from one of the many `R` mirrors.

6. To use [Java](https://www.java.com), you should download the Oracle distributed JDK.

6. When installing [Python](https://www.python.org), verify which python you

are using.

7. 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 ..

@subsection TuningDroid 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
