Usage: $0 [options]
|
||
|
||
When no options are specified, configure runs in interactive mode and you must
|
||
specify any required values manually. If one or more options are specified,
|
||
non-interactive configuration is started and any omitted values are defaulted.
|
||
|
||
PATH OPTIONS
|
||
|
||
--system Automatically set up the installation paths
|
||
for system-wide installation.
|
||
--prefix=[dir] The root install directory. If this is set then
|
||
all subdirectories will be adjusted accordingly.
|
||
[$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]
|
||
--module-dir=[dir] The location where the loadable modules are
|
||
stored.
|
||
[$PWD/run/modules]
|
||
--build-dir=[dir] The location to store files in while building.
|
||
|
||
|
||
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.
|
||
--help Show this message and exit.
|
||
--uid=[name] Sets the user to run InspIRCd as.
|
||
--socketengine=[name] Sets the socket engine to be used. Possible
|
||
values are $SELIST.
|
||
--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.
