Build

• Building SC from the command prompt see INSTALL:

  • Download current IFC EXPRESS file here and save it into folder e.g. ../stepcode/data/ifc4x2
  • cd stepcode
  • mkdir build
  • cd build
  • cmake .. -DSC_BUILD_SCHEMAS=ifc4x2 // Defaults to special value ALL, which builds all schemas in SC/data.
  • make -j12

  • make sdai_IFC4x2 generate_cpp_sdai_IFC4x2 lazy_sdai_IFC4x2 sdai_IFC4x2 p21read_sdai_IFC4x2 -j12

    • these binaries will be saved in ../stepcode/build/bin
    • use e.g. p21read_sdai_IFC4x2 like: ./bin/p21read_sdai_IFC4x2 ./bin/KIT-Bridge.ifc
  • make install // will put bin & lib in sc-install folder outside stepcode folder

WASM

• Developer’s Guide - WebAssembly
  • source ~/Documents/git/emsdk/emsdk_env.sh --build=Release

Visual Studio & C++

  • emcmake cmake .. -DSC_BUILD_SCHEMAS=ifc4x2
  • emmake make -j12
  • emmake make sdai_IFC4x2 -j12
  • emmake make install
  • emmake make sdai_IFC4x2 generate_cpp_sdai_IFC4x2 lazy_sdai_IFC4x2 sdai_IFC4x2 p21read_sdai_IFC4x2
• emmake make
