[yocto] DEPENDS only half working

[colin.helliwell at ln-systems.com]

I've got an odd problem with a pair of recipes:

App 'bar' uses 'libfoo', so I've set a DEPENDS in bar.bb - I can see this is
being half picked up, because 'bitbake bar' shows both builds being started.
However bar isn't waiting on libfoo - bar tries to compile before libfoo has
even finished configuring, let alone compiled and installed it's header
(foo_lib.h) into sysroot.

I think the recipes are probably otherwise correct - if I 'bitbake libfoo'
then 'bitbake bar' then all works.

I've looked at some simple lib recipes within poky (e.g. libwebp_0.4.3.bb /
webkitgtk_2.8.5.bb), and can't spot anything wrong/missing. Not sure if
libfoo should have any 'install' or similar sections, or any FILES_
settings, but I was [naively.?] hoping that the inherited classes will be
sorting out all that generic kinda stuff.

 

Anyone help please? 

 

libfoo.bb :

 

.

inherit autotools lib_package binconfig-disabled pkgconfig

RPROVIDES_${PN} = "libfoo"

PROVIDES_${PN} = "libfoo"

PR = "r0"

SRC_URI = " ...<src files>..   "

S = "${WORKDIR}"

 

 

bar.bb :

 

..

inherit autotools binconfig-disabled pkgconfig

DEPENDS_${PN} = "libfoo"

RDEPENDS_${PN} = "libfoo"

S = "${WORKDIR}"

SRC_URI = " ...<src files>..   "

EXTRA_OEMAKE = " CFLAGS=" -I${STAGING_DIR_TARGET}/usr/include/libfoo " "

EXTRA_OEMAKE += " LDFLAGS=" -lfoo " "

 

 

libfoo Makefile.am:

 

lib_LTLIBRARIES = libfoo.la

pkginclude_HEADERS = foo_lib.h  

libfoo_la_SOURCES = $(libfoo_a_HEADERS) foo_lib.c
