gawk: Additional Configuration Options
B.2.3 Additional Configuration Options
--------------------------------------
There are several additional options you may use on the 'configure'
command line when compiling 'gawk' from scratch, including:
'--disable-extensions'
Disable configuring and building the sample extensions in the
'extension' directory. This is useful for cross-compiling. The
default action is to dynamically check if the extensions can be
configured and compiled.
'--disable-lint'
Disable all lint checking within 'gawk'. The '--lint' and
'--lint-old' options (
Options) are accepted, but silently
do nothing. Similarly, setting the 'LINT' variable (
User-modified) has no effect on the running 'awk' program.
When used with the GNU Compiler Collection's (GCC's) automatic
dead-code-elimination, this option cuts almost 23K bytes off the
size of the 'gawk' executable on GNU/Linux x86_64 systems. Results
on other systems and with other compilers are likely to vary.
Using this option may bring you some slight performance
improvement.
CAUTION: Using this option will cause some of the tests in the
test suite to fail. This option may be removed at a later
date.
'--disable-mpfr'
Skip checking for the MPFR and GMP libraries. This is useful
mainly for the developers, to make sure nothing breaks if MPFR
support is not available.
'--disable-nls'
Disable all message-translation facilities. This is usually not
desirable, but it may bring you some slight performance
improvement.
'--enable-versioned-extension-dir'
Use a versioned directory for extensions. The directory name will
include the major and minor API versions in it. This makes it
possible to keep extensions for different API versions on the same
system without their conflicting with one another.
'--with-whiny-user-strftime'
Force use of the included version of the C 'strftime()' function
for deficient systems.
Use the command './configure --help' to see the full list of options
supplied by 'configure'.
