61 command is used in each of these directories to build and install the
62 things in that directory.
65 command in any directory or
66 subdirectory of those directories has the same effect as issuing the
67 same command in all subdirectories of that directory.
68 With no target specified, the things in that directory are just built.
70 A source tree is allowed to be read-only.
73 objects are usually built in a separate object directory hierarchy
74 specified by the environment variable
75 .Va MAKEOBJDIRPREFIX ,
81 For a given source directory, its canonical object directory

284 .Bl -tag -width ".Cm delete-old-libs"

317 Variables that influence all builds include:
318 .Bl -tag -width ".Va MAKEOBJDIRPREFIX"
320 Defines a set of debugging flags that will be used to build all userland
329 targets install binaries from the current

334 The directory hierarchy prefix where built objects will be installed.
337 defaults to the empty string.
338 .It Va MAKEOBJDIRPREFIX
339 Defines the prefix for directory names in the tree of built objects.
343 This variable should only be set in the environment and not via
347 If defined, compiler warnings will not cause the build to halt,
348 even if the makefile says otherwise.
351 Additionally, builds in
353 are influenced by the following

382 sub-directory named in this variable.
383 This variable is useful when debugging failed builds.
