|

| 10 | be used by Python, the primary language for this revamp. For more information

| 14 | Changing the output directory
|
|---|
| 15 | -----------------------------
|
|---|
| 16 |
|
|---|
| 17 | When switch between different VBox build settings it can be nice to have
|
|---|
| 18 | different output directories to avoid having to rebuild the whole source tree
|
|---|
| 19 | everything. One typical example is hardening, another is guest additions using
|
|---|
| 20 | crossbuild gcc w/ SDK. The latter is is simpler so that's the first example:
|
|---|
| 21 |
|
|---|
| 22 | .. code:: makefile
|
|---|
| 23 |
|
|---|
| 24 | ifdef VBOX_WITH_COMPATIBLE_LINUX_GUEST_PACKAGE
|
|---|
| 25 | PATH_OUT_BASE = $(PATH_ROOT)/add-out
|
|---|
| 26 | endif
|
|---|
| 27 |
|
|---|
| 28 | The following example is the typical developer setup, i.e. disable hardening by
|
|---|
| 29 | default but respect command line overrides (kmk VBOX_WITH_HARDENING=1):
|
|---|
| 30 |
|
|---|
| 31 | .. code:: make
|
|---|
| 32 |
|
|---|
| 33 | VBOX_WITH_HARDENING :=
|
|---|
| 34 | ifeq ($(VBOX_WITH_HARDENING),)
|
|---|
| 35 | VBOX_WITHOUT_HARDENING=1
|
|---|
| 36 | else
|
|---|
| 37 | PATH_OUT_BASE = $(PATH_ROOT)/hard-out
|
|---|
| 38 | endif
|
|---|

| 41 | Share tools download directory between trunk and branches
|
|---|
| 42 | ---------------------------------------------------------
|
|---|
| 43 |
|
|---|
| 44 | To avoid filling up your disk with unnecessary tool zip and tar.gz files, set
|
|---|
| 45 | the FETCHDIR variable in LocalConfig.kmk to point to a common directory for all
|
|---|
| 46 | VBox checkouts.
|
|---|
| 47 |
|
|---|
| 48 | .. code:: make
|
|---|
| 49 |
|
|---|
| 50 | FETCHDIR = $(HOME)/Downloads/FetchDir
