\`configure' configures qbittorrent v4.6.0beta1 to adapt to many kinds of systems. | |
Usage: $0 [OPTION]... [VAR=VALUE]... | |
To assign environment variables (e.g., CC, CFLAGS...), specify them as | |
VAR=VALUE. See below for descriptions of some of the useful variables. | |
Defaults for the options are specified in brackets. | |
Configuration: | |
-h, --help display this help and exit | |
--help=short display options specific to this package | |
--help=recursive display the short help of all the included packages | |
-V, --version display version information and exit | |
-q, --quiet, --silent do not print \`checking ...' messages | |
--cache-file=FILE cache test results in FILE [disabled] | |
-C, --config-cache alias for \`--cache-file=config.cache' | |
-n, --no-create do not create output files | |
--srcdir=DIR find the sources in DIR [configure dir or \`..'] | |
Installation directories: | |
--prefix=PREFIX install architecture-independent files in PREFIX | |
[$ac_default_prefix] | |
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX | |
[PREFIX] | |
By default, \`make install' will install all the files in | |
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify | |
an installation prefix other than \`$ac_default_prefix' using \`--prefix', | |
for instance \`--prefix=\$HOME'. | |
For better control, use the options below. | |
Fine tuning of the installation directories: | |
--bindir=DIR user executables [EPREFIX/bin] | |
--sbindir=DIR system admin executables [EPREFIX/sbin] | |
--libexecdir=DIR program executables [EPREFIX/libexec] | |
--sysconfdir=DIR read-only single-machine data [PREFIX/etc] | |
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com] | |
--localstatedir=DIR modifiable single-machine data [PREFIX/var] | |
--runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run] | |
--libdir=DIR object code libraries [EPREFIX/lib] | |
--includedir=DIR C header files [PREFIX/include] | |
--oldincludedir=DIR C header files for non-gcc [/usr/include] | |
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share] | |
--datadir=DIR read-only architecture-independent data [DATAROOTDIR] | |
--infodir=DIR info documentation [DATAROOTDIR/info] | |
--localedir=DIR locale-dependent data [DATAROOTDIR/locale] | |
--mandir=DIR man documentation [DATAROOTDIR/man] | |

Optional Features: | |
--disable-option-checking ignore unrecognized --enable/--with options | |
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no) | |
--enable-FEATURE[=ARG] include FEATURE [ARG=yes] | |
--enable-dependency-tracking | |
do not reject slow dependency extractors | |
--disable-dependency-tracking | |
speeds up one-time build | |
--enable-silent-rules less verbose build output (undo: "make V=1") | |
--disable-silent-rules verbose build output (undo: "make V=0") | |
--enable-debug Enable debug build | |
--enable-stacktrace Enable stacktrace feature (default=auto) | |
--disable-gui Disable the GUI for headless running. Disables | |
QtDBus and the GeoIP Database. | |
--enable-systemd Install the systemd service file (headless only). | |
--disable-webui Disable the WebUI. | |
--disable-qt-dbus Disable use of QtDBus (GUI only) | |
Optional Packages: | |
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes] | |
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) | |
--with-boost[=ARG] use Boost library from a standard location | |
(ARG=yes), from the specified location (ARG=<path>), | |
or disable it (ARG=no) [ARG=yes] | |
--with-boost-libdir=LIB_DIR | |
Force given directory for boost libraries. Note that | |
this will override library path detection, so use | |
this parameter only if default library detection | |
fails and you know exactly where your boost | |
libraries are located. | |
Some influential environment variables: | |
CC C compiler command | |
CFLAGS C compiler flags | |
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a | |
nonstandard directory <lib dir> | |
LIBS libraries to pass to the linker, e.g. -l<library> | |
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if | |
you have headers in a nonstandard directory <include dir> | |
CXX C++ compiler command | |
CXXFLAGS C++ compiler flags | |
PKG_CONFIG path to pkg-config utility | |
PKG_CONFIG_PATH | |
directories to add to pkg-config's search path | |
PKG_CONFIG_LIBDIR | |
path overriding pkg-config's built-in search path | |
QT_QMAKE value of host_bins for Qt5Core >= 5.15.2, overriding pkg-config | |
Qt5Svg_CFLAGS | |
C compiler flags for Qt5Svg, overriding pkg-config | |
Qt5Svg_LIBS linker flags for Qt5Svg, overriding pkg-config | |
libtorrent_CFLAGS | |
C compiler flags for libtorrent, overriding pkg-config | |
libtorrent_LIBS | |
linker flags for libtorrent, overriding pkg-config | |
openssl_CFLAGS | |
C compiler flags for openssl, overriding pkg-config | |
openssl_LIBS | |
linker flags for openssl, overriding pkg-config | |
zlib_CFLAGS C compiler flags for zlib, overriding pkg-config | |
zlib_LIBS linker flags for zlib, overriding pkg-config | |
Use these variables to override the choices made by `configure' or to help | |
it to find libraries and programs with nonstandard names/locations. | |
