Description

Running lighttpd 1.4.20 and lua 5.1.4 causes an issue on CentOS 4 with kernel 2.6.18-8.1.14.el5.028stab045.1PAE i686 i686 i386 GNU/Linux

Having both built lua 5.1.4 from source and installed from rpm does not resolve this issue. With the install from source complied a shared library.

mkdir -p /usr/local/lua
cd /usr/local/lua
wget http://www.lua.org/ftp/lua-5.1.4.tar.gz
tar -zxvf lua-5.1.4.tar.gz
cd /usr/local/lua/lua-5.1.4
make linux
make test
make install
cp /usr/local/lua/lua-5.1.4/etc/lua.pc /usr/local/lib/pkgconfig/
ranlib /usr/local/lib/liblua.a

cd /usr/local/lib
gcc -shared -o liblua.5.1.4.so /usr/local/lib/liblua.a
ln -s liblua.5.1.4.so liblua.so

  1. lighttpd lua recompile
    cd /var/tmp
    wget http://www.lighttpd.net/download/lighttpd-1.4.20.tar.gz
    tar -xzvf lighttpd-1.4.20.tar.gz
    cd /var/tmp/lighttpd-1.4.20
    make distclean
    ./configure --with-zlib --with-bzip2 --with-openssl=/usr/local/ssl --with-lua LUA_LIBS=/usr/local/lib LUA_CFLAGS=-I/usr/local/bin
    Having tried lua in both /usr/bin and usr/local/bin seems to make no difference, once mod-magnet is added to the lighttpd.conf the following error results.

Starting lighttpd: 2009-04-08 09:05:43: (plugin.c.165) dlopen() failed for: /usr/local/lib/mod_magnet.so /usr/local/lib/mod_magnet.so: undefined symbol: lua_touserdata
2009-04-08 09:05:43: (server.c.610) loading plugins finally failed

Any help would be appreciated. Thanks

This has previously been put through the forum with no luck as well. http://redmine.lighttpd.net/boards/2/topics/593

  • Status changed from New to Invalid
  • Target version deleted (1.4.20)

The LUA_LIBS var must include "-llua". You really should have lighty find the lua libs via pkg-config.
Target version != affected version, and 1.4.22 is the current release.

Update:

I just thought I would update this with some additional information.

I upgraded a server from 1.4.18 to 1.4.25 and ran into the same problem again.

#Starting lighttpd: 2010-01-06 15:18:35: (plugin.c.165) dlopen() failed for: /usr/lib/lighttpd/mod_magnet.so /usr/lib/lighttpd/mod_magnet.so: cannot open shared object file: No such file or directory
#2010-01-06 15:18:35: (server.c.614) loading plugins finally failed

I noted that the actual lighttpd libs were in /usr/local/lib and ran make uninstall on the 1.4.18 again and on the 1.4.25 then reconfigured lighttpd 1.4.25 with:

./configure --libdir=/usr/local/lib --with-zlib --with-bzip2 --with-openssl=/usr/local/ssl --with-lua

The same thing, a bit further investigation showed that the /etc/rc.d/init.d/lighttpd file had the incorrect path in it. It was referencing /usr/sbin/lighttpd instead of /usr/local/sbin/lighttpd modifying this resolved the issue. Just flagging it up if anyone else runs into any similar module loading problems.
