Hey Thomas,
I retried a build when libpcap was absent and was able to reproduce the same
errors as you did.
Error: cannot find librte_pcapng.so.25.1 in
dpdk-build/build-arm64-generic-gcc/install
Error: cannot find librte_graph.so.25.1 in
dpdk-build/build-arm64-generic-gcc/install
Error: cannot find librte_node.so.25.1 in
dpdk-build/build-arm64-generic-gcc/install
Error: cannot find librte_pdump.so.25.1 in
dpdk-build/build-arm64-generic-gcc/install
These Errors are coming from ABI check: dpdk/devtools/check-abi.sh:49
I see in this function that it is checking for the existence of these
libraries, which will be absent when libpcap is absent. Is there a way to have
the abi-check skip these libraries if they are not built?
Or better question: How does the abi-check even know about these libraries if
they are never built?
Thanks!
Dylan

Sorry I did not investigate, but there is probably a different installation of
the pcap library.
I have this in a config file:
pcaparm=$deps/libpcap/build-aarch64/install # requires big changes in DPDK
#export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$pcaparm/lib/pkgconfig
I don't remember what are the big changes required, and why it is disabled.
Checking Meson, libpcap is indeed not found on aarch64:
Run-time dependency libpcap found: NO (tried pkgconfig)
Library pcap found: NO
Can you check whether the error can be related to the absence of libpcap?
