Hi, i am trying to compile with nginx 1.21.4 with this configure:
./configure (...) --add-module=./ngx_http_websocket_stat_module
configure runs normal, but 'make' return error:
make ....... -o objs/addon/ngx_http_websocket_stat_module/ngx_http_websocket_stat_module.o \ /opt/ngx_http_websocket_stat_module/ngx_http_websocket_stat_module.c In file included from /usr/include/string.h:494, from src/os/unix/ngx_linux_config.h:27, from src/core/ngx_config.h:26, from src/core/ngx_core.h:12, from /opt/ngx_http_websocket_stat_module/ngx_http_websocket_stat_format.h:18, from /opt/ngx_http_websocket_stat_module/ngx_http_websocket_stat_module.c:1: In function ‘memcpy’, inlined from ‘send_close_packet’ at /opt/ngx_http_websocket_stat_module/ngx_http_websocket_stat_module.c:674:5, inlined from ‘check_ws_age.isra.1.part.2’ at /opt/ngx_http_websocket_stat_module/ngx_http_websocket_stat_module.c:302:9, inlined from ‘check_ws_age.isra.1’ at /opt/ngx_http_websocket_stat_module/ngx_http_websocket_stat_module.c:296:1, inlined from ‘my_send’ at /opt/ngx_http_websocket_stat_module/ngx_http_websocket_stat_module.c:320:9: /usr/include/x86_64-linux-gnu/bits/string_fortified.h:34:10: error: ‘__builtin_memcpy’ forming offset 20 is out of the bounds [0, 19] [-Werror=array-bounds] return __builtin___memcpy_chk (__dest, __src, __len, __bos0 (__dest)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[1]: *** [objs/Makefile:2079: objs/addon/ngx_http_websocket_stat_module/ngx_http_websocket_stat_module.o] Error 1 make[1]: Leaving directory '/opt/nginx-1.21.4' make: *** [Makefile:10: build] Error 2
