I started a Centos 8.2 vm. No libibverbs installed by default. I compiled DPDK v20.11.3 and installed it in builddir/install The output you provided on .pc files matches what I see. No reference to libibverbs in installed DPDK: [dpdk@centos8 dpdk]$ grep -r ibverbs builddir/install [dpdk@centos8 dpdk]$ I have no problem building and linking OVS (current master branch). Here is what I see in my working OVS environment (I mean in the directory where I have the OVS sources, and where I ran sh boot.sh + PKG_CONFIG_PATH=... ./configure --with-dpdk): [dpdk@centos8 ovs]$ grep -r ibverbs . ./acinclude.m4: OVS_FIND_DEPENDENCY([verbs_init_cq], [ibverbs], [libibverbs]) ./acinclude.m4: OVS_FIND_DEPENDENCY([verbs_init_cq], [ibverbs], [libibverbs]) ./autom4te.cache/traces.0: OVS_FIND_DEPENDENCY([verbs_init_cq], [ibverbs], [libibverbs]) ./autom4te.cache/traces.0: OVS_FIND_DEPENDENCY([verbs_init_cq], [ibverbs], [libibverbs]) ./autom4te.cache/traces.0:m4trace:configure.ac:197: -1- OVS_FIND_DEPENDENCY([verbs_init_cq], [ibverbs], [libibverbs]) ./autom4te.cache/traces.0:m4trace:configure.ac:197: -1- OVS_FIND_DEPENDENCY([verbs_init_cq], [ibverbs], [libibverbs]) ./autom4te.cache/output.0:for ac_lib in '' ibverbs; do ./autom4te.cache/output.0: as_fn_error $?

"unable to find libibverbs, install the dependency package" "$LINENO" 5 OVS requests ibverbs only if mlx drivers are present in DPDK build (+ option RTE_IBVERBS_LINK_DLOPEN iirc). For your issue, things that come to mind are an outdated build directory, maybe following a pull from OVS sources, or maybe you had ibverbs installed in the past on this system, and now it has been removed. Did you compile OVS from a scratch/clean environment? -- David Marchand _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
