# 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
|
|
# - others obvious... :-/

# Format of a pattern to check for, one per line:
|
|
# pattern := var_name : tool_pattern OR tool_pattern
|
|
# tool_pattern := tool_test OR tool_pattern || tool_test
|
|
# tool_test := tool=regexp OR tool
|
|
# tool := basename of the tool OR absolute pathname to the tool
|
|
# regexp := valid grep(1) extended regular expression, $( tool --version)
|
|
# will be matched against this regexp.
|
|
#
|
|
# 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:
|
|
# bash:bash=^GNU bash, version 3\.
|
|
# - if ${bash} is set and non-null, does nothing
|
|
# - else ensures that bash exists in the PATH, and that
|
|
# "$( "$( which bash )" --version |head -n 1 )"
|
|
# matches the regexp '^GNU bash, version 3\.'
|
|
# - if so, then sets bash="$( which bash )"
|
|
# autoconf=(GNU Autoconf) || autoconf2.50
|
|
# - does not look at an existing variable
|
|
# - ensures that:
|
|
# - 'autoconf' is to be found in the PATH, and that $( autoconf --version |head -n 1 )
|
|
# 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-${VERSION} to adapt to many kind of systems.
|
|
|
|
USAGE: ./configure [OPTION]...
|
|
|
|
Defaults for the options are specified in brackets.
|
|
|
|
Configuration:
|
|
-h, --help display this help and exit
|
|
|
|
Installation directories:
|
|
--prefix=PREFIX install files in PREFIX [${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-install=PATH Specify the full PATH to GNU install
|
|
--with-make=PATH Specify the full PATH to GNU make
|
|
--with-grep=PATH Specify the full PATH to GNU grep
|
|
--with-sed=PATH Specify the full PATH to GNU sed
|
|
--with-awk=PATH Specify the full PATH to GNU awk
|
|
--with-bash=PATH Specify the full PATH to bash >= 3.0
