# config.mak.dist - sample musl-cross-make configuration
#
# Copy to config.mak and edit as desired.
#

# There is no default TARGET; you must select one here or on the make
# command line. Some examples:

# TARGET = i486-linux-musl
# TARGET = x86_64-linux-musl
# TARGET = arm-linux-musleabi
# TARGET = arm-linux-musleabihf
# TARGET = sh2eb-linux-muslfdpic
# ...

# By default, cross compilers are installed to ./output under the top-level
# musl-cross-make directory and can later be moved wherever you want them.
# To install directly to a specific location, set it here. Multiple targets
# can safely be installed in the same location. Some examples:

# OUTPUT = /opt/cross
# OUTPUT = /usr/local

# By default, latest supported release versions of musl and the toolchain
# components are used. You can override those here, but the version selected
# must be supported (under hashes/ and patches/) to work. For musl, you
# can use "git-refname" (e.g. git-master) instead of a release. Setting a
# blank version for gmp, mpc, and mpfr will suppress download and in-tree
# build of these libraries and instead depend on pre-installed libraries.

# BINUTILS_VER = 2.25.1
# GCC_VER = 5.2.0
# MUSL_VER = git-master
# GMP_VER =
# MPC_VER =
# MPFR_VER =

# Something like the following can be used to produce a static-linked
# toolchain that's deployable to any system with matching arch, using
# an existing musl-targeted cross compiler. This only # works if the
# system you build on can natively (or via binfmt_misc and # qemu) run
# binaries produced by the existing toolchain (in this example, i486).

# COMMON_CONFIG += CC="i486-linux-musl-gcc -static --static" CXX="i486-linux-musl-g++ -static --static"

# Recommended options for smaller build for deploying binaries:

# COMMON_CONFIG += CFLAGS="-g0 -Os" CXXFLAGS="-g0 -Os" LDFLAGS="-s"

# Recommended options for faster/simpler build:

# COMMON_CONFIG += --disable-nls
# GCC_CONFIG += --enable-languages=c,c++
# GCC_CONFIG += --disable-libquadmath --disable-decimal-float
# GCC_CONFIG += --disable-multilib

# You can keep the local build path out of your toolchain binaries and
# target libraries with the following, but then gdb needs to be told
# where to look for source files.

# COMMON_CONFIG += --with-debug-prefix-map=$(PWD)=

# The following are options needed to make certain targets work right.
# They may be moved to main build logic rather than config.mak at some
# point in the future.
