This is a minimal change to start to require the new minimum bootstrap. Taking advantage of the newer bootstap to simplify and improve code is left to be done in separate CLs. For #64751.

|
|
# Environment variables that control make.bash:
|
|
#
|
|
# GOHOSTARCH: The architecture for host tools (compilers and
|
|
# binaries). Binaries of this type must be executable on the current
|
|
# system, so the only common reason to set this is to set
|
|
# GOHOSTARCH=386 on an amd64 machine.
|
|
#
|
|
# GOARCH: The target architecture for installed packages and tools.
|
|
#
|
|
# GOOS: The target operating system for installed packages and tools.
|
|
#
|
|
# GO_GCFLAGS: Additional go tool compile arguments to use when
|
|
# building the packages and commands.
|
|
#
|
|
# GO_LDFLAGS: Additional go tool link arguments to use when
|
|
# building the commands.
|
|
#
|
|
# CGO_ENABLED: Controls cgo usage during the build. Set it to 1
|
|
# to include all cgo related files, .c and .go file with "cgo"
|
|
# build directive, in the build. Set it to 0 to ignore them.
|
|
#
|
|
# GO_EXTLINK_ENABLED: Set to 1 to invoke the host linker when building
|
|
# packages that use cgo. Set to 0 to do all linking internally. This
|
|
# controls the default behavior of the linker's -linkmode option. The
|
|
# default value depends on the system.
|
|
#
|
|
# GO_LDSO: Sets the default dynamic linker/loader (ld.so) to be used
|
|
# by the internal linker.
|
|
#
|
|
# CC: Command line to run to compile C code for GOHOSTARCH.
|
|
# Default is "gcc". Also supported: "clang".
|
|
#
|
|
# CC_FOR_TARGET: Command line to run to compile C code for GOARCH.
|
|
# This is used by cgo. Default is CC.
|
|
#
|
|
# CC_FOR_${GOOS}_${GOARCH}: Command line to run to compile C code for specified ${GOOS} and ${GOARCH}.
|
|
# (for example, CC_FOR_linux_arm)
|
|
# If this is not set, the build will use CC_FOR_TARGET if appropriate, or CC.
|
|
#
|
|
# CXX_FOR_TARGET: Command line to run to compile C++ code for GOARCH.
|
|
# This is used by cgo. Default is CXX, or, if that is not set,
|
|
# "g++" or "clang++".
|
|
#
|
|
# CXX_FOR_${GOOS}_${GOARCH}: Command line to run to compile C++ code for specified ${GOOS} and ${GOARCH}.
|
|
# (for example, CXX_FOR_linux_arm)
|
|
# If this is not set, the build will use CXX_FOR_TARGET if appropriate, or CXX.
|
|
#
|
|
# FC: Command line to run to compile Fortran code for GOARCH.
|
|
# This is used by cgo. Default is "gfortran".
|
|
#
|
|
# PKG_CONFIG: Path to pkg-config tool. Default is "pkg-config".
|
|
#
|
|
# GO_DISTFLAGS: extra flags to provide to "dist bootstrap".
|
|
# (Or just pass them to the make.bash command line.)
|
|
#
|
|
# GOBUILDTIMELOGFILE: If set, make.bash and all.bash write
|
|
# timing information to this file. Useful for profiling where the
|
|
# time goes when these scripts run.
|
|
#
|
|
# GOROOT_BOOTSTRAP: A working Go tree >= Go 1.22.6 for bootstrap.
|
|
# If $GOROOT_BOOTSTRAP/bin/go is missing, $(go env GOROOT) is
|
|
# tried for all "go" in $PATH. By default, one of $HOME/go1.22.6,
|
|
# $HOME/sdk/go1.22.6, or $HOME/go1.4, whichever exists, in that order.
