Re: [Gumstix-users] bitbake newb error: ERROR: No providers of build target xxxxx_1.0.0.bb (for [] )

[Terry K. <kl...@kl...>]

Further to this - the _underscore_ is used by bitbake to parse the
package version so that it uses the recipe name to fetch the required
version of whatever.
If you need to upgrade to a newer version then (usually) you just need
to copy the recipe with the new version in the name after the
underscore...

heres one I made for Dansguardian: the recipe is (was) called
dansguardian_2.9.9.1.bb

note that in the recipe SRC_URI it fetches dansguardian-${PV} - with
${PV} being the bits after the underscore in the recipe name - in this
case 2.9.9.1 - so it fetches dansguardian-2.9.9.1.tar.gz. 

----------------------------------------------------------
DESCRIPTION = "Web content filter"

SRC_URI =
"http://usmirror.dansguardian.org/downloads/2/Beta/dansguardian-${PV}.tar.gz"

LICENSE = "GPL"
PR = "r2"

DEPENDS = "zlib"
RDEPENDS = "clamav"

EXTRA_OECONF = --enable-pcre=no --enable-clamd 

inherit autotools

-------------------------------------------------------

When a new source update was released I simply copied my recipe as
dansguardian_2.9.9.2.bb - the recipe name changed (after the underscore)
so the recipe automatically knows to fetch the newer version cos of
${PV}... 

(BTW autotools makes recipes so easy :)
