Re: [vpp-dev] VPP - 'No debugging symbols found in /usr/lib/vpp plugins/dpdk plugin.so'
Not sure why there is no debug symbols in the dpdk build, but if you want to debug DPDK in VPP, the easiest way is probably to recompile VPP & DPDK in debug mode. To do that, in VPP source tree: ~# make rebuild DPDK_DEBUG=y And then you can run your VPP debug build like this: ~# ./build-root/install-vpp_debug-native/vpp/bin/vpp -c /etc/vpp/startup.conf ben > -Original Message- > From: vpp-dev@lists.fd.io On Behalf Of Guangming > Sent: Tuesday, November 29, 2022 2:44 > To: vpp-dev > Subject: Re: [vpp-dev] VPP - 'No debugging symbols found in /usr/lib/vpp > plugins/dpdk plugin.so' > > Hi ,Gábor > Not debug version, but i have installed vpp-debuginfo.x86_64.rpm, my os > is centos > The rte_eth_tx_prepare in frame 6 is in file dpdk_plugin.so, the > diffrence is > that rte_eth_tx_prepare is in VPP, the i40e_xmit_pkts is in dpdk . > Maybe the dpdk static lib has no symbols.

Hi ,Gábor Not debug version, but i have installed vpp-debuginfo.x86_64.rpm, my os is centos The rte_eth_tx_prepare in frame 6 is in file dpdk_plugin.so, the diffrence is that rte_eth_tx_prepare is in VPP, the i40e_xmit_pkts is in dpdk . Maybe the dpdk static lib has no symbols. I did not find how to rebuild dpdk static lib with symbol in VPP project.

Hi Guangming,
Do you use the debug version of the plugins, too?

[vpp-dev] VPP - 'No debugging symbols found in /usr/lib/vpp plugins/dpdk plugin.so'
Hi, In FDIO vpp 21.01, while testing TCP traffic observing a seg fault resulting in vpp abort. Generated the core dump and ran gdb on it. bt was pointing to 'dpdk_plugin' in vpp $ gdb vpp warning: Unable to find matching inferior's thread library, thread debugging will not be available. Core was generated by `vpp -c /etc/vpp/startup.conf'.

But still we are getting above warning. In FDIO vpp 21.01 version, can dpdk_plugin be built with debug symbols ? Any flag or additional code changes needed ? Can you please help on this regard.
