# All absolutely required tools, one per line to ease diff.
|
|
# See function 'has_or_abort, below, for syntax
|
|
# - Hopefully, if gcc is present, then all associated tools will be
|
|
# - awk must be GNU awk
|
|
# - makeinfo for building docs, even if discarded later on

# Format of a pattern to check for, one per line:
|
|
# pattern := tool_test OR pattern|tool_test
|
|
# tool_test := tool/regexp
|
|
# tool := name of the tool OR absolute pathname to the tool
|
|
# regexp := valid grep(1) extended regular expression OR empty
|
|
#
|
|
# In case a pattern list is given (eg foo|bar|buz), then tests are performed
|
|
# from left to right, stopping at the first matching test (like the shell
|
|
# would parse 'foo || bar || buz' ).
|
|
#
|
|
# Examples:
|
|
# /bin/bash/^GNU bash, version 3\.
|
|
# will ensure that /bin/bash exists, and that $(/bin/bash --version)
|
|
# matches the regexp '^GNU bash, version 3\.'
|
|
# autoconf/(GNU Autoconf)|autoconf2.50/
|
|
# will ensure that:
|
|
# - 'autoconf' is to be found in the PATH, and that $(autoconf
|
|
# --version) matches the regexp '(GNU Autoconf)' (which btw is
|
|
# the signature of autoconf >= 2.50),
|
|
# OR that:
|
|
# - 'autoconf2.50' is to be found in the PATH

\`configure' configures crosstool-NG ${VERSION} to adapt to many kind of systems.
|
|
|
|
USAGE: ./configure [OPTION]...
|
|
|
|
Defaults for the options are specified in brackets.
|
|
|
|
Configuration:
|
|
-h, --help display this help and exit
|
|
--force force ./configure to complete, even if one or more
|
|
tools were not found. Use at your own risk, only if
|
|
you know what you are doing!
|
|
|
|
Installation directories:
|
|
--prefix=PREFIX install files in PREFIX [${PREFIX_DEFAULT}]
|
|
--local don't install, and use current directory
|
|
|
|
By default, \`make install' will install all the files in
|
|
\`${PREFIX_DEFAULT}/bin', \`${PREFIX_DEFAULT}/lib' etc. You can specify
|
|
an installation prefix other than \`${PREFIX_DEFAULT}' using \`--prefix',
|
|
for instance \`--prefix=\${HOME}'.
|
|
|
|
For better control, use the options below.
|
|
|
|
Fine tuning of the installation directories:
|
|
--bindir=DIR user executables [PREFIX/bin]
|
|
--libdir=DIR object code libraries [PREFIX/lib]
|
|
--docdir=DIR info documentation [PREFIX/share/doc]
|
|
--mandir=DIR man documentation [PREFIX/share/man]
|
|
|
|
Optional Features:
|
|
--with-contrib=XXX Include externally contributed features found in the
|
|
contrib/ sub-directory. Set to a comma-separated list
|
|
of features. Use 'all' to use all contributions, and
|
|
'list' to see which are available.
