The TFEL/Config library is mostly used internally by TFEL and provides some information related to the project.

getDefaultSubstitutions: TFEL’s default substitutions

The getDefaultSubstitutions function returns some default substitutions used by MFront when reading configuration files and tfel-check when analysing .check files.

General substitutions

• TFEL_CXX_STANDARD: the C++ standard used by the project.

Supported compilers

• TFEL_GXX_COMPILER: path the g++ compiler. The value associated with this key is determined as follows, by order of priority:

  1. by passing the variable TFEL_GXX_COMPILER during the invocation of cmake.
  2. by using g++ as the main compiler to compile TFEL
  3. by searching g++ using cmake’s find_program function.

• TFEL_CLANGXX_COMPILER: path to LLVM clang++ compiler. The value associated with this key is determined as follows, by order of priority:

  1. by passing the variable TFEL_CLANGXX_COMPILER during the invocation of cmake,
  2. by using clang++ as the main compiler to compile TFEL,
  3. by searching clang++ using cmake’s find_program function.

• TFEL_ICPX_COMPILER: path to INTEL’s icpx compiler. The value associated with this key is determined as follows, by order of priority:

  1. by passing the variable TFEL_ICPX_COMPILER during the invocation of cmake,
  2. by using icpx as the main compiler to compile TFEL,
  3. by searching icpx using cmake’s find_program function.

• TFEL_ACPP_COMPILER: path to AdaptativeCpp acpp compiler. The value associated with this key is determined as follows, by order of priority:

  1. by passing the variable TFEL_ACPP_COMPILER during the invocation of cmake,
  2. by searching acpp using cmake’s find_program function.

• TFEL_NVHPC_COMPILER: path to NVIDIA’s nvhpc compiler. The value associated with this key is determined as follows, by order of priority:

  1. by passing the variable TFEL_NVHPC_COMPILER during the invocation of cmake,
  2. by using nvhpc as the main compiler to compile TFEL,
  3. by searching nvhpc using cmake’s find_program function.

• TFEL_NVCC_COMPILER: path to NVIDIA’s nvhcp as found by FindCUDAToolkit.

• TFEL_HIPCC_COMPILER: path to AMD’s hipcc compiler. The value associated with this key is determined as follows, by order of priority:

  1. by passing the variable TFEL_HIPCC_COMPILER during the invocation of cmake,
  2. by searching hipcc using cmake’s find_program function.

Substitutions related to the HIPCC compiler

• TFEL_HIPCC_FLAGS: additional flags to be passed to thehipcc` compiler.
• TFEL_HIP_INCLUDE_DIR: paths to HIP headers

Substitutions related to the CUDA platform

• TFEL_CUDA_PATH: path to NVIDIA’s CUDA toolkit as found by CMake’s FindCUDAToolkit module.
• TFEL_CUDA_LIBRARY_DIR: path to the libraries of the NVIDIA’s CUDA toolkit as found by CMake’s FindCUDAToolkit module.
