[vpp-dev] Error in loading sample_plugin.so

[Shashi Kant Singh]

Hi

I am using:  VPP 18.01

I compiled sample plugin with:
make build  SAMPLE_PLUGIN=yes

it failed so I added

[root@vbbubng12-shashi10 vpp]# git diff 
src/examples/sample-plugin/sample/sample.c
diff --git a/src/examples/sample-plugin/sample/sample.c 
b/src/examples/sample-plugin/sample/sample.c

+sample_main_t sample_main;

  *
[root@vbbubng12-shashi10 vpp]#


After this compilation goes through, but when I try to run as
make run

It still gives me this error:

load_one_plugin:142:

Any solution for this:
