Lighttpd

In my local build,

nm .libs/mod_magnet.so | grep lua

$ objdump -T /usr/lib64/liblua.so | grep lua_geti
0000000000011430 g    DF .text    0000000000000595  Base        lua_getinfo
00000000000090d0 g    DF .text    00000000000000d0  Base        lua_geti

Would you please describe in a little bit more detail the problem you are having?

Reported on IRC:

(plugin.c.226) dlopen() failed for: /usr/local/lib/mod_magnet.so /usr/local/lib/mod_magnet.so: undefined symbol: lua_geti

We use lua_geti when lua-version >= 5.2, but it is only available in 5.3.

That lua_geti() could be changed to lua_rawgeti(), but I prefer lua_pushglobaltable()
