# GYP supports the following environment variables to control the paths to the
# toolchain:
#
# * CC - The C compiler
# * CXX - The C++ compiler
# * AR - The archive tool
# * NM - The symbol name tool
# * READELF - The ELF metadata tool
#
# If any are not specified, they default to the system's installed copy of that
# tool.
#
# Note that overriding the linker is NOT supported. The C or C++ compiler will
# always be used as a front-end to the linker.
#
# Any of these may have "_host" or "_target" appended to indicate that they
# should only be used when compiling for the host or for the target when
# cross-compiling. If GYP is cross-compiling and a specific "_host" or "_target"
# tool is not found, it will fall back to the normal tool. e.g. If there is no
# "CC_host", host builds will use "CC".
#
# It is recommended to always set GYP_CROSSCOMPILE to 1 when cross-compiling.

# |export_variables| is a dictionary containing the variables to set.  Relative
# paths are interpreted as being relative to this file.
export_variables = {
  # Although we aren't actually cross-compiling in this build, settings.gypi
  # relies on the cross-compiler's separation of host and target build
  # artifacts. By setting this variable, we force GYP to use cross-compilation
  # mode even though both modes use the same compiler binary.
  'GYP_CROSSCOMPILE': '1',

  # Typically, you will want to set these to the paths to your system's
  # toolchain. but for this example, we'll just use the system install of GCC.
  'CC': 'gcc',
  'CXX': 'g++',
  'AR': 'ar',

  # Alternatively, here's how you could use the GCC as the "host" toolchain and
  # Clang as the "target" toolchain:

  # 'CC_target': 'clang',
  # 'CXX_target': 'clang++',
  # 'AR_target': 'llvm-ar',
  #
  # 'CC_host': 'gcc',
  # 'CXX_host': 'g++',
  # 'AR_host': 'ar',
