If one or more options are specified, non-interactive configuration is started and any omitted values are defaulted. PATH OPTIONS --system Automatically set up the installation paths for system-wide installation. --prefix=[dir] The root install directory. If this is set then all subdirectories will be adjusted accordingly. [$PWD/run] --binary-dir=[dir] The location where the main server binary is stored. [$PWD/run/bin] --config-dir=[dir] The location where the configuration files and SSL certificates are stored. [$PWD/run/conf] --data-dir=[dir] The location where the data files, such as the pid file, are stored. [$PWD/run/data] --log-dir=[dir] The location where the log files are stored. [$PWD/run/logs] --manual-dir=[dir] The location where the manual files are stored. [$PWD/run/manuals] --module-dir=[dir] The location where the loadable modules are stored. [$PWD/run/modules] EXTRA MODULE OPTIONS --enable-extras=[extras] Enables a comma separated list of extra modules. --disable-extras=[extras] Disables a comma separated list of extra modules. --list-extras Shows the availability status of all extra modules. MISC OPTIONS --clean Remove the configuration cache file and start the interactive configuration wizard. --disable-interactive Disables the interactive configuration wizard. --distribution-label=[text] Sets a distribution specific version label in the build configuration. --gid=[id|name] Sets the group to run InspIRCd as. --help Show this message and exit. --socketengine=[name] Sets the socket engine to be used. Possible values are $SELIST. --uid=[id|name] Sets the user to run InspIRCd as. --update Updates the build environment. FLAGS CXX=[name] Sets the C++ compiler to use when building the server. If not specified then the build system will search for c++, g++, clang++ or icpc.
