Hi Greg,

 I have a custom recipe that copies a .so, that libMotors.so calls functions in

another libcanfestival.so.

When I first added in the copy of the .so I didn't have an RDEPENDS
and Yocto printed out an warning listing the package that it wanted. I
added an RDEPENDS_${PN} with all of the packages listed, but I'm still

getting an error for the first libMotors.so:

ERROR: userconfig-1.0-r0 do_package_qa: QA Issue:
/home/sakura/lib/libMotors.so.1.0.0 contained in package userconfig
requires libcanfestival.so, but no providers found in
RDEPENDS_userconfig? [file-rdeps]

In userdepends I added:

RDEPENDS_${PN} += "canfestival libelf libgcrypt pcsc-lite-lib qtbase

qtdeclarative qtserialport zint"

Package canfestival_3-asc in has:

FILES_${PN} = "/usr/lib/libcanfestival.so /usr/lib/libcanfestival_unix.so

/usr/lib/libcanfestival_can_socket.so"

.so files are installed in the -dev package even with the line above.

Please have a look here:
https://wiki.yoctoproject.org/wiki/TipsAndTricks/Packaging_Prebuilt_Librarie
s#Non-versioned_Libraries
if there is really no way for you to avoid having a non-versioned library.

First, the canfestival package that I have doesn't create versioned libraries, only the non-versioned .so's.

I changed the canfestival .bb to:

SOLIBS = ".so.*"
SOLIBSDEV = ".so"

FILES_${PN} = " ${libdir}/lib*${SOLIBSDEV}"
FILES_SOLIBSDEV ?= " ${libdir}/lib*${SOLIBSDEV}"
FILES_${PN}-dev = " /usr/include/canfestival/*.h ${FILES_SOLIBSDEV}"

And I get the following error:

ERROR: canfestival-3-asc-r01 do_package_qa: QA Issue: -dev package contains non-symlink .so: canfestival-dev path '/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/canfestival/3-asc-r01/packages-split/canfestival-dev/usr/lib/libcanfestival_unix.so'

ERROR: canfestival-3-asc-r01 do_package_qa: QA run found fatal errors. Please consider fixing them.

I removed the ${FILES_SOLIBSDEV} from the FILES_${PN}-dev and then I get:

ERROR: userconfig-1.0-r0 do_package_qa: QA run found fatal errors. Please consider fixing them.

It looks like the first warning is the key to the ERROR of not finding libcanfestival.so, but not getting errors for the other 2 libraries.

I looked in the build for canfestival and nowhere is there a bin/libcanfestival.so. Any ideas of how this could be created or referenced?

You can check if .so files are part of a package by using `oe-pkgdata-util find-
path /usr/lib/libcanfestival.so`

Cheers,
Quentin
