'configure' configures GNU C Library (see version.h) 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]
|

Some influential environment variables:

||
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>
|
||
TEST_CC C compiler for testing
|
||
CPP C preprocessor
|
||
CXX C++ compiler command
|
||
CXXFLAGS C++ compiler flags
|
||
TEST_CXX C++ compiler for testing
|
||
|
||
Use these variables to override the choices made by 'configure' or to help
|
||
it to find libraries and programs with nonstandard names/locations.
