When compiling and installing nginx source code, I saw ./configure --help, which I didn’t quite understand
--with-http_ssl_module enable ngx_http_ssl_module
--with-http_v2_module enable ngx_http_v2_module
--with-http_realip_module enable ngx_http_realip_module
--with-http_addition_module enable ngx_http_addition_module
--with-http_xslt_module enable ngx_http_xslt_module
--with-http_xslt_module=dynamic enable dynamic ngx_http_xslt_module
--with-http_image_filter_module enable ngx_http_image_filter_module
--with-http_image_filter_module=dynamic
--with-select_module enable select module
--without-select_module disable select module
--with-poll_module enable poll module
--without-poll_module disable poll module Do the above http_ssl module and http_v2 module need to be specified in ./configure before adding and using this function?
If all --with needs to be specified after ./configure to compile before it can be used, then what's the point of --without?
For example, if the above select_module needs to be specified by ./configure --with-select_module before it can be compiled and used, what is the significance of the --without-select_module compilation configuration option?

Some modules are compiled by default, and some are not compiled. For those that are compiled by default, if you don’t want to use them, you can use without. For those that are not compiled by default, if you want to use them, use with.
This is how it is described in the official documentation
For those that have both with and without, such as theselect_modulemodule, this module will
