I found error error: this statement may fall through [-Werror=implicit-fallthrough=] when installing nginx from source and add RTMP module for my streaming server. Here is the full error after compile the nginx source:
/opt/nginx-rtmp-module/ngx_rtmp_eval.c: In function ‘ngx_rtmp_eval’:
/opt/nginx-rtmp-module/ngx_rtmp_eval.c:160:17: error: this statement may fall through [-Werror=implicit-fallthrough=]
make[1]: *** [objs/Makefile:1438: objs/addon/nginx-rtmp-module/ngx_rtmp_eval.o] Error 1

make[1]: *** [objs/Makefile:1466: objs/addon/nginx-rtmp-module/ngx_rtmp_codec_module.o] Error 1
make[1]: Leaving directory ‘/root/installer/nginx-1.19.7’
make: *** [Makefile:8: build] Error 2
And here is my solutions:
$ ./configure –prefix=/opt/nginx
$ make CFLAGS=’-Wno-implicit-fallthrough’
$ sudo make install
Hope this help
