Re: [ovs-discuss] what's wrong with these codes ?

Thank you for all, I have found root cause: the "struct ovsdb_idl" is defined in ovsdb-idl.c file, so "idl->table_by_name" will report warning. The function I want is to quarry tables in idl at the outside of ovsdb-idl.c. I don't know "ovsdb-idl.h" supply this function in API. 2015-03-06 9:01 GMT

It does not work after adding #include "shash.h" in the .c file. It warns again. And if missing #include "shash.h", will the "struct shash_node *node;" report warning ? 2015-03-06 0:51 GMT+08:00 Ben Pfaff : > Missing #include "shash.h" > > On Thu, Mar 05, 2015 at 09:23:43PM +0800, yewgang wrote:
