115 When no options are specified, configure runs in interactive mode and you must
116 specify any required values manually. If one or more options are specified,
117 non-interactive configuration is started and any omitted values are defaulted.
121 --system Automatically set up the installation paths
122 for system-wide installation.
123 --prefix=[dir] The root install directory. If this is set then
124 all subdirectories will be adjusted accordingly.
126 --binary-dir=[dir] The location where the main server binary is
129 --config-dir=[dir] The location where the configuration files and
130 SSL certificates are stored.
132 --data-dir=[dir] The location where the data files, such as the
133 pid file, are stored.
135 --log-dir=[dir] The location where the log files are stored.
137 --manual-dir=[dir] The location where the manual files are stored.
139 --module-dir=[dir] The location where the loadable modules are
142 --script-dir=[dir] The location where the scripts, such as the
143 init scripts, are stored.
148 --enable-extras=[extras] Enables a comma separated list of extra modules.
149 --disable-extras=[extras] Disables a comma separated list of extra modules.
150 --list-extras Shows the availability status of all extra
155 --clean Remove the configuration cache file and start
156 the interactive configuration wizard.
157 --disable-auto-extras Disables automatically enabling extra modules
158 for which the dependencies are available.
159 --disable-interactive Disables the interactive configuration wizard.
160 --distribution-label=[text] Sets a distribution specific version label in
161 the build configuration.
162 --gid=[id|name] Sets the group to run InspIRCd as.
163 --help Show this message and exit.
164 --socketengine=[name] Sets the socket engine to be used. Possible
166 --uid=[id|name] Sets the user to run InspIRCd as.
167 --update Updates the build environment with the settings
173 CXX=[name] Sets the C++ compiler to use when building the
174 server. If not specified then the build system
175 will search for c++, g++, clang++ or icpc.
