Hi,
I got the following error upon running this.
error: non-aggregate type 'struct lcb_create_st' cannot be initialized with an initializer list
struct lcb_create_st crst = {
^ ~
Please change the struct initialisation of "crst" as follows -
lcb_create_st crst;
memset(&crst, 0, sizeof(crst));
crst.version = 3;
crst.v.v3.connstr = CONNSTR;
