# -----------------------------------------------------------------------------
# A Sample build.mk
#
# Uncomment one of the following BuildFlavour settings to get the desired
# overall build type, and then tweak the options in the relevant section
# below.
# -------- Build profiles -----------------------------------------------------
# Uncomment one of these to select a build profile below:
# Full build with max optimisation and everything enabled (very slow build)
#BuildFlavour = perf
# As above but build GHC using the LLVM backend
#BuildFlavour = perf-llvm
# Perf build configured for a cross-compiler
#BuildFlavour = perf-cross
# Fast build with optimised libraries, no profiling (RECOMMENDED):
#BuildFlavour = quick
# Fast build with optimised libraries, no profiling, with LLVM:
#BuildFlavour = quick-llvm
# Fast build configured for a cross compiler
#BuildFlavour = quick-cross
# Even faster build. NOT RECOMMENDED: the libraries will be
# completely unoptimised, so any code built with this compiler
# (including stage2) will run very slowly:
#BuildFlavour = quickest
# Profile the stage2 compiler:
#BuildFlavour = prof
# A development build, working on the stage 1 compiler:
#BuildFlavour = devel1
# A development build, working on the stage 2 compiler:
#BuildFlavour = devel2
# A build with max optimisation that still builds the stage2 compiler
# quickly. Compiled code will be the same as with "perf". Programs
# will compile more slowly.
#BuildFlavour = bench
# As above but build GHC using the LLVM backend
#BuildFlavour = bench-llvm
# Bench build configured for a cross-compiler
#BuildFlavour = bench-cross
# -------- Miscellaneous variables --------------------------------------------
# Set to V = 0 to get prettier build output.
# Please use V = 1 when reporting GHC bugs.
V = 1
# Should all enabled warnings (see mk/warnings.mk) be turned into errors?
#WERROR=-Werror
# After stage 1 and the libraries have been built, you can uncomment this line:
#stage=2
# Then stage 1 will not be touched by the build system, until
# you comment the line again. This is a useful trick for when you're
# working on stage 2 and want to freeze stage 1 and the libraries for
# a while.
# Uncomment the following line to enable building DPH
#BUILD_DPH=YES
GhcLibWays = $(if $(filter $(DYNAMIC_GHC_PROGRAMS),YES),v dyn,v)
# Uncomment the following to force `integer-gmp` to use the in-tree GMP 5.0.4
# (other sometimes useful configure-options: `--with-gmp-{includes,libraries}`)
