B.2.2 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 (see Options) are accepted, but silently do nothing. Similarly, setting the LINT variable (see 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-nls

Disable all message-translation facilities. This is usually not desirable, but it may bring you some slight performance improvement.

--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.
