How to compile VAL

Windows

Linux

macOS

  • Requirements:

    • Xcode packages: cmake make g++ gcc flex bison
    • Note: easier to simply install Xcode in its entirety; necessary packages automatically downloaded
  • IDE:

  • Scripts

    • Note: all called (internally as well) build and clean scripts must be run through dos2unix

    • (scripts/build_macos_dev.sh): script for native macOS build

      • Binaries can be found in build/macos64/Release/bin
    • (scripts/clean_macos_dev.sh): script for cleaning out built binaries

    • (scripts/linux/setup_flex_bison.sh): build script to generate flex and bison header/implementation files from libraries/VAL/src/Parser/pddl+.l and libraries/VAL/src/Parser/pddl+.y

    • Note: flex on macOS currently causing compatibility issues

      • Do not run setup_flex_bison.sh
      • Use current Windows-generated flex header file at [libraries/VAL/src/Parser/pddl+.lex.yy.h]
    • Note: bison on macOS running well

      • Edit YACC file at [libraries/VAL/src/Parser/pddl+.y] as needed
      • Run bison command from script (bison pddl+.y -o pddl+.cpp) directly through terminal
