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