Unknown api: fastcgi / Unknown api: http: need more verbose error message #96
Description
Migrating cppcms to a new server, at first I couldn't get cppcms running at all, even a simple "hello world" cppcms web site.
I the logs, there were mentions of:
Unknown api: fastcgi
or:
Unknown api: http
Since I was migrating and upgrading the whole operating system, the whole toolchain was being upgraded at the same time: gcc, mod_fastcgi, new C++ standards, etc.
After much searching and investigating, it turned out to be a wrong configuration (apache vhost socket vs config.js service.socket....).
A more verbose output when failing to connect to a socket, or in case of a wrong setting in config.js would help.
The message "Unknown api: fastcgi" sent me down the wrong track since mod_fastcgi is not supported and I wondered if the new C++ language + new GCC compiler had broken something in that library. The problem was not with fastcgi at all, and cppcms should not report this.
I file this request here in case anyone else is facing the same problem.
Also, read carefully the official wiki:
