With these installed, compile with the usual "make".
FastCGI is backwards compatible with CGI, so you can run a2web under most http servers. We have tested busybox httpd, lighttpd and apache.
If you want to set up passworded access to a2web, that belongs to your web server configuration.
If you need better access times, you can configure FastCGI; if not, regular CGI uses less RAM.
xmlrpc-c should be able to use any of the client backends, but only curl has been tested.
Since a2web is a CGI app, there is no "make install" target. Copy a2web.cgi to your cgi-bin directory, and one or more themes to your www space.
