Product Version3.2.10.3 
Summary0004316: loadmodule fails with error "file not found" when file is present
DescriptionAfter modifying include/config.h so that Unrealircd would run as the user ircd, Unrealircd generated a "no such file or directory" error when attempting to load the commands module.

Steps To Reproducemake clean
Modified include/config.h to run ircd as user ircd rather than root
./Config
make
unreal start
Additional Informationsu root
cd ~
wget http://www.unrealircd.com/downloads/Unreal3.2.10.3.tar.gz
tar zxf Unreal3.2.10.3.tar.gz
cd Unreal3.2.10.3
pico /include/config.h
    searched (CTRL-w) for "#define CHROOTDIR"
    uncommented the line so CHROOTDIR would be defined
        
    searched (CTRL-w) for "#define IRC_USER"
    uncommented both the #define IRC_USER and IRC_GROUP
    Edited both values to "ircd"
    Exit(CTRL-x) and save
        
pico configure
    searched (CTRL-w) for "$CFLAGS -export-dynamic"
    modified CFLAGS="$CFLAGS -export-dynamic" ==> CFLAGS="$CFLAGS -Wl,-export-dynamic"
    searched (CTRL-w) for "$ac_cv_c_compiler_gnu"
    modified the value for ac_cv_pic to "-std=gnu89 -fPIC -DPIC -shared"
    Exit (CTRL-x) and save
pico configure.ac
    searched for the FLAGS="$CFLAGS -export-dynamic"
    editted the line to: CFLAGS="$CFLAGS -Wl,-export-dynamic"
    removed the line containing: ac_cv_pic="-fPIC -DPIC -shared"

Sounds like you are not familiar with chrooting, let me explain: chroot()'ing means that the process will make a certain directory the new root directory. What this means in practice with UnrealIRCd: when you define CHROOTDIR on UnrealIRCd you tell it to lock itself up in DPATH.
DPATH is what you answer to "What directory are all the server configuration files in?" which is where you answered "/usr/local/etc/Unreal"

This means that after booting, the IRCd will make "/usr/local/etc/Unreal" the new "/" (in the eyes of the ircd process).

So if you want to load a module in /usr/local/etc/Unreal/modules/blah.so you need to load "modules/blah.so".

You tried to load /usr/local/lib/Unreal/commands.so but this will actually translate to /usr/local/etc/Unreal/usr/local/lib/Unreal/commands.so. It's impossible to load the real /usr/local/lib/... as this is outside the chroot of /usr/local/etc/Unreal.

Hope I didn't confuse you further :P. In that case a google on "chroot" may be more helpful.

Thank you for clarifying chrooting. I relocated the modules to "/usr/local/etc/Unreal/modules" and then updated my unrealircd.conf to load the required modules as "modules/commands.so" and "modules/cloak.so".

This resolved the issue with the modules and my misunderstanding of chrooting. I am now looking to figure out why UnrealIRCd does not fully start with the following message:

root@mydev1server:~ # unreal start

I'm closing this issue as it has turned into a support matter rather than a bug with UnrealIRCd. bugs.unrealircd.org is for reporting bugs that may be reproduced or to request features.

Please use http://forums.unrealircd.com or go to our IRC channel #unreal-support on irc.unrealircd.com (irc://irc.unrealircd.com/unreal-support) for further assistance with getting Unreal to boot.
