It’s worth checking that the symbol in question is actually exported. As part of upgrading, you may have started using a different toolchain.
$ nm -go <file>.o | grep <missing-symbol> From: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> On Behalf Of Satya Murthy Sent: Wednesday, September 29, 2021 6:43 AM To: vpp-dev@lists.fd.io Subject: [vpp-dev] vlib_get_plugin_symbol returning null after upgrading to 21.06 version Hi, We are trying to upgrade to fdio.2106 version from a previous version. After upgrading to 21.06 version with our custom plugins, we are seeing that vlib_get_plugin_symbol() to resolve a symbol from another plugin is always returning null. This was working fine in the earlier version. I cross checked that load_one_plugin() is successful in loading all the plugins, before we call the vlib_get_plugin_symbol(). Any pointers on what could be happening here ? -- Thanks & Regards, Murthy
