编辑 nginx 时报错 ngx_http_sticky_modulec:295:42: error: ‘iphp’ undeclared (first use in this function)

如题，nginx 1.15.10 +centos 7.7 ，这个报错应该怎么理解的 提前谢过：
/www/server/nginx/src/nginx-sticky-module/ngx_http_sticky_module.c: In function ‘ngx_http_get_sticky_peer’:

/www/server/nginx/src/nginx-sticky-module/ngx_http_sticky_module.c 295 行左右的代码如下：
static ngx_int_t
288 ngx_http_get_sticky_peer(ngx_peer_connection_t *pc, void *data)
289 {
290 time_t now = ngx_time();
291 uintptr_t m;
292 ngx_str_t route;
293 ngx_int_t ret, selected_peer = -1;
294 ngx_uint_t tmp, n, i;
295 ngx_http_sticky_srv_conf_t *cOnf= iphp->sticky_conf;
296 ngx_http_upstream_rr_peer_t *peer = NULL;
297 ngx_http_sticky_peer_data_t *iphp = data;
