# Cosmopolitan Core Build Rules

|
|
# DESCRIPTION
|
|
#
|
|
# This file shows GNU Make how to convert between file types, based on
|
|
# their extensions. We use everyday, ordinary, boring, and ubiquitous
|
|
# system commands for everything, e.g. as, cc, ld, etc. with plain and
|
|
# simple shell-script wrappers, e.g. build/assemble and build/compile.
|
|
# Those veneers abstract away most of the boring trivialities, to keep
|
|
# our makefiles pristine and readable.

# LOCAL UNIT TESTS
|
|
#
|
|
# We always run unit tests as part of the normal `make` invocation. you
|
|
# may override the $(TESTARGS) variable to do things such as enable the
|
|
# benchmarking feature. For example:
|
|
#
|
|
# TESTARGS = -b
|
|
#
|
|
# May be specified in your ~/.cosmo.mk file. You can also use this to
|
|
# enable things like function tracing. For example:
|
|
#
|
|
# TESTARGS = ----ftrace
|
|
# .PLEDGE += prot_exec
|
|
#
|
|
# You could then run a command like:
|
|
#
|
|
# make -j8 o//test/libc/calls/openbsd_test.com.runs
|
|
#
|
|
# You need PROT_EXEC permission since ftrace morphs the binary. It's
|
|
# also worth mentioning that the pledge.com command can simulate what
|
|
# Landlock Make does:
|
|
#
|
|
# o//tool/build/pledge.com \
|
|
# -v. -p 'stdio rpath wpath cpath tty prot_exec' \
|
|
# o//test/libc/calls/openbsd_test.com \
|
|
# ----ftrace
|
|
#
|
|
# This is useful in the event a test binary should run by itself, but
|
|
# fails to run beneath Landlock Make. It's also useful sometimes to
|
|
# override the verbosity when running tests:
|
|
#
|
|
# make V=5 TESTARGS=-b o//test/libc/calls/openbsd_test.com.runs
|
|
#
|
|
# This way, if for some reason a test should fail but calls exit(0),
|
|
# then the stdout/stderr output, which would normally be suppressed,
|
|
# will actually be displayed.
