# Example for build-time configuration options.
# Copy this to `config.mk` and adjust as needed. The values shown below are
# usage examples, whereas the first one always represents the default value.
# Please note that you should trigger a clean build (`make clean && make`) after
# changing any of these settings.

# Build settings #
##################

# Note: The following settings are expected to be provided mainly on the `make`
# command line. If needed, however, they can be specified here.

# If set to `release`, build without debug symbols and optimize the binary.
#type ?= debug
#type ?= release

# If set to `yes`, enable further warnings. If set to `all`, enable even more
# warnings, including those that could be false positive.
#wextra ?= yes
#wextra ?= no
#wextra ?= all

# If set to `yes`, make warnings terminate the build process.
#werror ?= no
#werror ?= yes

# If set to `yes`, print all commands issued during build.
#verbose ?= no
#verbose ?= yes

# Enable sanitizers. As some of them are incompatible, there are multiple
# options: `yes` means to use the address and UB sanitizers, `memory` (only
# available with Clang) the memory sanitizer, and `thread` (only available with
# Clang) the thread sanitizer.
#sanitize ?= no
#sanitize ?= yes
#sanitize ?= memory
#sanitize ?= thread

# If set to `yes`, terminate the program on sanitizer errors.
#sanitize-strict ?= no
#sanitize-strict ?= yes

# If set to `yes`, build a binary instrumented for coverage analysis.
#coverage ?= no
#coverage ?= yes
