   1 #
   2 # Basic build targets:
   3 #   all         all main tools and the shared library
   4 #   static      build static bnaries, requires static version of the libraries
   5 #   test        run the full testsuite
   6 #   install     install to default location (/usr/local)
   7 #   clean       clean built binaries (not the documentation)
   8 #   clean-all   clean as above, clean docs and generated files
   9 #
  10 # Tuning by variables (environment or make arguments):
  11 #   V=1            verbose, print command lines (default: quiet)
  12 #   C=1            run checker before compilation (default checker: sparse)
  13 #   D=1            debugging build, turn off optimizations
  14 #   D=dflags       dtto, turn on additional debugging features:
  15 #                  verbose - print file:line along with error/warning messages
  16 #                  trace   - print trace before the error/warning messages
  17 #                  abort   - call abort() on first error (dumps core)
  18 #                  all     - shortcut for all of the above
  19 #                  asan    - enable address sanitizer compiler feature
  20 #                  tsan    - enable thread sanitizer compiler feature
  21 #                  ubsan   - undefined behaviour sanitizer compiler feature
  22 #                  bcheck  - extended build checks
  23 #   W=123          build with warnings (default: off)
  24 #   DEBUG_CFLAGS   additional compiler flags for debugging build
  25 #   EXTRA_CFLAGS   additional compiler flags
  26 #   EXTRA_LDFLAGS  additional linker flags
  27 #
  28 # Testing-specific options (see also tests/README.md):
  29 #   TEST=GLOB      run test(s) from directories matching GLOB
  30 #   TEST_LOG=tty   print name of a command run via the execution helpers
  31 #   TEST_LOG=dump  dump testing log file when a test fails
  32 #
  33 # Static checkers:
  34 #   CHECKER        static checker binary to be called (default: sparse)
  35 #   CHECKER_FLAGS  flags to pass to CHECKER, can override CFLAGS
  36 #
  37
  38 # Export all variables to sub-makes by default
