After having a look in the code the below 2 structures causing this are defined in teh directives with PCRE only and not with PCRE2

#if (NGX_PCRE)

typedef struct {

ngx_http_script_code_pt code;
ngx_http_regex_t *regex;
ngx_array_t *lengths;
uintptr_t size;
uintptr_t status;
uintptr_t next;

unsigned test:1;
unsigned negative_test:1;
unsigned uri:1;
unsigned args:1;

/* add the r->args to the new arguments */
unsigned add_args:1;

unsigned redirect:1;
unsigned break_cycle:1;

ngx_str_t name;

} ngx_http_script_regex_code_t;

typedef struct {

ngx_http_script_code_pt code;

unsigned uri:1;
unsigned args:1;

/* add the r->args to the new arguments */
unsigned add_args:1;

unsigned redirect:1;

} ngx_http_script_regex_end_code_t;

#endif

Could you please let me know if this is the right way of compiling or niginx1.24 does not support PCRE2 library on Ubuntu....
