`configure' configures this package to adapt to many kinds of systems.
|
|
|
|
Usage: gcc/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.
|
|
|
|
