I am trying to add the open source "procps" package to my working Yocto build. This package installs a bunch of binaries that replace those provided by BusyBox. I only want one of these binaries - pgrep
.
In my layer I created a bbappend file named "procps_%bbappend". It is picked up by the build, compiles successfully, but then fails on the install. The error messages seem to indicate that the do_install()
and do_install_append()
hooks are not overridden completely.
How can I change my bitbake bbappend file to only install the pgrep
utility and none of the other standard installs from the "procps" package?
Here is my bbappend file that fails:
do_install () {
install -d ${D}${base_bindir}
mv ${D}/../build/pgrep ${D}/bin/pgrep
}
do_install_append () {
install -d ${D}${base_bindir}
mv ${D}/../build/pgrep ${D}/bin/pgrep
}
bindir_progs = ""
base_bindir_progs = ""
base_sbindir_progs = ""
Here is the entire "procps" bitbake recipe:

There's a few bits of confusion here:
install
that's what it's for.${D}/../build/
is not right, you probably want ${B}
instead -- but that should also be the default directory for do_install() so you shouldn't need it at all.You could let the original do_install() do what it wants, and then remove the bits you don't want in do_install_append()... but I think modifying the package so much is not a great idea: what if another package runtime depends on procps and expects the tools you removed?
Some alternatives for you:
PACKAGES =+ ${PN}-pgrep
and set FILES_${PN}-pgrep = "${bindir}/pgrep"
: then you could install only the new tiny procps-pgrep package instead of procps. This might need some tweaking to get right because of the alternatives system procps uses...
