# 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.

|
|

|

# artifacts. By setting this variable, we force GYP to use cross-compilation
|
|
# mode even though both modes use the same compiler binary.

# 'CXX_target': 'clang++',

# 'CC_host': 'gcc',

# 'CXX_host': 'g++',
