4 === Infrastructure for Waf-based packages
6 [[waf-package-tutorial]]
8 ==== +waf-package+ tutorial
10 First, let's see how to write a +.mk+ file for a Waf-based package, with
13 ------------------------
14 01: ################################################################################
18 05: ################################################################################
20 07: LIBFOO_VERSION = 1.0
21 08: LIBFOO_SOURCE = libfoo-$(LIBFOO_VERSION).tar.gz
22 09: LIBFOO_SITE = http://www.foosoftware.org/download
23 10: LIBFOO_CONF_OPTS = --enable-bar --disable-baz
24 11: LIBFOO_DEPENDENCIES = bar
26 13: $(eval $(waf-package))
27 ------------------------
29 On line 7, we declare the version of the package.
31 On line 8 and 9, we declare the name of the tarball (xz-ed tarball
32 recommended) and the location of the tarball on the Web. Buildroot
33 will automatically download the tarball from this location.
35 On line 10, we tell Buildroot what options to enable for libfoo.
37 On line 11, we tell Buildroot the depednencies of libfoo.
39 Finally, on line line 13, we invoke the +waf-package+
40 macro that generates all the Makefile rules that actually allows the
43 [[waf-package-reference]]
45 ==== +waf-package+ reference
47 The main macro of the Waf package infrastructure is +waf-package+.
48 It is similar to the +generic-package+ macro.
50 Just like the generic infrastructure, the Waf infrastructure works
51 by defining a number of variables before calling the +waf-package+
54 First, all the package metadata information variables that exist in
55 the generic infrastructure also exist in the Waf infrastructure:
56 +LIBFOO_VERSION+, +LIBFOO_SOURCE+, +LIBFOO_PATCH+, +LIBFOO_SITE+,
57 +LIBFOO_SUBDIR+, +LIBFOO_DEPENDENCIES+, +LIBFOO_INSTALL_STAGING+,
58 +LIBFOO_INSTALL_TARGET+.
60 An additional variable, specific to the Waf infrastructure, can
63 * +LIBFOO_NEEDS_EXTERNAL_WAF+ can be set to +YES+ or +NO+ to tell
64 Buildroot to use the bundled +waf+ executable. If set to +NO+, the
65 default, then Buildroot will use the waf executable provided in the
66 package source tree; if set to +YES+, then Buidlroot will download,
67 install waf as a host tool and use it to build the package.
69 * +LIBFOO_WAF_OPTS+, to specify additional options to pass to the
70 +waf+ script at every step of the package build process: configure,
71 build and installation. By default, empty.
73 * +LIBFOO_CONF_OPTS+, to specify additional options to pass to the
74 +waf+ script for the configuration step. By default, empty.
76 * +LIBFOO_BUILD_OPTS+, to specify additional options to pass to the
77 +waf+ script during the build step. By default, empty.
79 * +LIBFOO_INSTALL_STAGING_OPTS+, to specify additional options to pass
80 to the +waf+ script during the staging installation step. By default,
83 * +LIBFOO_INSTALL_TARGET_OPTS+, to specify additional options to pass
84 to the +waf+ script during the target installation step. By default,
