113 When no options are specified, configure runs in interactive mode and you must
114 specify any required values manually. If one or more options are specified,
115 non-interactive configuration is started and any omitted values are defaulted.
119 --system Automatically set up the installation paths
120 for system-wide installation.
121 --prefix=[dir] The root install directory. If this is set then
122 all subdirectories will be adjusted accordingly.
124 --binary-dir=[dir] The location where the main server binary is
127 --config-dir=[dir] The location where the configuration files and
128 SSL certificates are stored.
130 --data-dir=[dir] The location where the data files, such as the
131 pid file, are stored.
133 --log-dir=[dir] The location where the log files are stored.
135 --manual-dir=[dir] The location where the manual files are stored.
137 --module-dir=[dir] The location where the loadable modules are
143 --enable-extras=[extras] Enables a comma separated list of extra modules.
144 --disable-extras=[extras] Disables a comma separated list of extra modules.
145 --list-extras Shows the availability status of all extra
150 --clean Remove the configuration cache file and start
151 the interactive configuration wizard.
152 --disable-interactive Disables the interactive configuration wizard.
153 --distribution-label=[text] Sets a distribution specific version label in
154 the build configuration.
155 --gid=[id|name] Sets the group to run InspIRCd as.
156 --help Show this message and exit.
157 --socketengine=[name] Sets the socket engine to be used. Possible
159 --uid=[id|name] Sets the user to run InspIRCd as.
160 --update Updates the build environment.
165 CXX=[name] Sets the C++ compiler to use when building the
166 server. If not specified then the build system
167 will search for c++, g++, clang++ or icpc.
