=== Infrastructure for Waf-based packages

|
|
==== +waf-package+ tutorial
|
|
|
|
First, let's see how to write a +.mk+ file for a Waf-based package, with
|
|
an example :
|
|
|
|
------------------------
|
|
01: ################################################################################
|
|
02: #
|
|
03: # libfoo
|
|
04: #
|
|
05: ################################################################################
|
|
06:
|
|
07: LIBFOO_VERSION = 1.0
|
|
08: LIBFOO_SOURCE = libfoo-$(LIBFOO_VERSION).tar.gz
|
|
09: LIBFOO_SITE = http://www.foosoftware.org/download
|
|
10: LIBFOO_CONF_OPTS = --enable-bar --disable-baz
|
|
11: LIBFOO_DEPENDENCIES = bar
|
|
12:
|
|
13: $(eval $(waf-package))
|
|
------------------------
|
|
|
|
On line 7, we declare the version of the package.
|
|
|
|
On line 8 and 9, we declare the name of the tarball (xz-ed tarball
|
|
recommended) and the location of the tarball on the Web. Buildroot
|
|
will automatically download the tarball from this location.
|
|
|
|
On line 10, we tell Buildroot what options to enable for libfoo.
|
|
|
|
On line 11, we tell Buildroot the dependencies of libfoo.
|
|
|
|
Finally, on line line 13, we invoke the +waf-package+
|
|
macro that generates all the Makefile rules that actually allows the
|
|
package to be built.
|
|
|
|
[[waf-package-reference]]
|
|
|
|
==== +waf-package+ reference
|
|
|
|
The main macro of the Waf package infrastructure is +waf-package+.
|
|
It is similar to the +generic-package+ macro.
|
|
|
|
Just like the generic infrastructure, the Waf infrastructure works
|
|
by defining a number of variables before calling the +waf-package+
|
|
macro.
|
|
|
|
First, all the package metadata information variables that exist in
|
|
the generic infrastructure also exist in the Waf infrastructure:
|
|
+LIBFOO_VERSION+, +LIBFOO_SOURCE+, +LIBFOO_PATCH+, +LIBFOO_SITE+,
|
|
+LIBFOO_SUBDIR+, +LIBFOO_DEPENDENCIES+, +LIBFOO_INSTALL_STAGING+,
|
|
+LIBFOO_INSTALL_TARGET+.
|
|
|
|
An additional variable, specific to the Waf infrastructure, can
|
|
also be defined.
|
|
|
|
* +LIBFOO_SUBDIR+ may contain the name of a subdirectory inside the
|
|
package that contains the main wscript file. This is useful,
|
|
if for example, the main wscript file is not at the root of
|
|
the tree extracted by the tarball. If +HOST_LIBFOO_SUBDIR+ is not
|
|
specified, it defaults to +LIBFOO_SUBDIR+.
|
|
|
|
* +LIBFOO_NEEDS_EXTERNAL_WAF+ can be set to +YES+ or +NO+ to tell
|
|
Buildroot to use the bundled +waf+ executable. If set to +NO+, the
|
|
default, then Buildroot will use the waf executable provided in the
|
|
package source tree; if set to +YES+, then Buildroot will download,
|
|
install waf as a host tool and use it to build the package.
|
|
|
|
* +LIBFOO_WAF_OPTS+, to specify additional options to pass to the
|
|
+waf+ script at every step of the package build process: configure,
|
|
build and installation. By default, empty.
|
|
|
|
* +LIBFOO_CONF_OPTS+, to specify additional options to pass to the
|
|
+waf+ script for the configuration step. By default, empty.
|
|
|
|
* +LIBFOO_BUILD_OPTS+, to specify additional options to pass to the
|
|
+waf+ script during the build step. By default, empty.
|
|
|
|
* +LIBFOO_INSTALL_STAGING_OPTS+, to specify additional options to pass
|
|
to the +waf+ script during the staging installation step. By default,
|
|
empty.
|
|
|
|
* +LIBFOO_INSTALL_TARGET_OPTS+, to specify additional options to pass
|
|
to the +waf+ script during the target installation step. By default,
|
|
empty.
