[UE] mod_magent - undefined symbol: lua_gettop
Added by vlrk over 2 years ago
Hi All,
I am trying to use lighttpd with lua CGI working.
My enviroment is as below.
Centos 7 lighttpd-1.4.66 lua 5.4.4 export LUA_CFLAGS=-I/usr/local/include export LUA_LIBS=-L/usr/local/lib ./configure --without-pcre2 --with-lua=5.4
my lighttpd.conf is as below
#cat /home/labuser/nginx/lighttpd.conf server.document-root = "/usr/local/nginx/html" server.port = 3000 server.modules = ( "mod_magnet" ) mimetype.assign = ( ".html" => "text/html", ".txt" => "text/plain", ".jpg" => "image/jpeg", ".png" => "image/png" )
Now when I try to verify config , it shows error as below
# /home/labuser/nginx/lighttpd-1.4.66/src/lighttpd -tt -f /home/labuser/nginx/lighttpd.conf 2022-08-25 01:29:54: (plugin.c.202) dlopen() failed for: /usr/local/lib/mod_magnet.so /usr/local/lib/mod_magnet.so: undefined symbol: lua_gettop 2022-08-25 01:29:54: (server.c.1285) loading plugins finally failed
Any help / direction to overcome will be very helpfull.
Thanks

I think our build system only tests lua5.3, so I recommend using that for now. I also assume you should have seen some warnings about this in the build logs.

thanks stbuehler,
I am beginner with lighttpd and lua , trying to get some basic lua page working.
I am trying get lua working with mod_magnet and fastcgi binary magnet.
I tried two magent.c varient one from jan.kneschke.de/downloads/lua/ and other from
https://github.com/blitmap/lua-magnet/
Both results with 500 internal error
my lighttpd.conf looks as below.
var.log_root = "/var/log/lighttpd" var.server_root = "/var/www" var.state_dir = "/var/run" var.home_dir = "/var/lib/lighttpd" var.conf_dir = "/etc/lighttpd" server.pid-file = state_dir + "/lighttpd.pid" server.errorlog = log_root + "/error.log" server.document-root = "/usr/local/nginx/html" debug.log-file-not-found = "enable" debug.log-request-header = "enable" debug.log-request-handling = "enable" debug.log-response-header = "enable" debug.log-condition-cache = "enable" debug.log-condition-handling = "enable" debug.log-request-header-on-error = "enable" debug.log-state-handling = "enable" debug.log-timing = "enable" server.port = 3000 fastcgi.debug = 1 server.modules = ( "mod_indexfile", "mod_access", "mod_alias", "mod_redirect", "mod_magnet", "mod_auth", "mod_cgi", "mod_fastcgi", "mod_accesslog", ) mimetype.assign = ( ".html" => "text/html", ".lua" => "text/html", ".txt" => "text/plain", ".jpg" => "image/jpeg", ".png" => "image/png" ) fastcgi.server = ( ".lua" => ( ("socket" => "/tmp/lua-fcgi.socket", "bin-path" => "/usr/local/bin/magnet", "max-procs" => 8 ) ) )
and my hello.lua file looks as below
print([[Status: 200 Content-Type: text/html <html> <head> <title> Congratulations! </title> </head> <body> Lua appears to work. </body></html>]])
where as if I remove fastcgi.server section from conf , instead of running the print comamnd as lua script it display as plain text with all the file content in browser.
If any other simple way (rather than this) , where I can make simple lua script working with lighttpd also would be great.
any inputs/pointers would be highly appreciated.
Thanks

Pick one or the other, not both. None of the following shows that you tried anything with mod_magnet, and what you do in your FastCGI backend is rather off topic here.
I tried two magent.c varient one from jan.kneschke.de/downloads/lua/ and other from
The first is more a "proof-of-concept" and really old and the latter even says "dead". Why would you use these?...

You really need a blank line between HTTP/CGI headers and the body.
And did you even take a look at the log files?
