|
||||
'configure' configures MPFR 4.2.2 to adapt to many kinds of systems.
|
||||
|
||||
Usage: ../configure [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
|
||||
[/usr/local]
|
||||
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
|
||||
[PREFIX]
|
||||
|
||||
By default, 'make install' will install all the files in
|
||||
'/usr/local/bin', '/usr/local/lib' etc. You can specify
|
||||
an installation prefix other than '/usr/local' 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]
|
||||

||||
--libexecdir=DIR program executables [EPREFIX/libexec]

|
||||
--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]
|
||||

|
||||
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]

|
||||

|
||||
|
||||
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>
|
||||
CPP C preprocessor
|
||||
LT_SYS_LIBRARY_PATH
|
||||
User-defined run-time library search path.
|
||||
|
||||
Use these variables to override the choices made by 'configure' or to help
|
||||
it to find libraries and programs with nonstandard names/locations.

||||

||||
