- \`configure' configures gold 0.1 to adapt to many kinds of systems.
- Usage: $0 [OPTION]... [VAR=VALUE]...
- To assign environment variables (e.g., CC, CFLAGS...), specify them as
- VAR=VALUE. See below for descriptions of some of the useful variables.
- Defaults for the options are specified in brackets.
- Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking ...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
- Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
- By default, \`make install' will install all the files in
- \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
- an installation prefix other than \`$ac_default_prefix' using \`--prefix',
- for instance \`--prefix=\$HOME'.
- For better control, use the options below.
- Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

- --with-gold-ldflags=FLAGS additional link flags for gold
- --with-gold-ldadd=LIBS additional libraries for gold
- --with-system-zlib use installed libz
- Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
- CXX C++ compiler command
- CXXFLAGS C++ compiler flags
- YACC The `Yet Another Compiler Compiler' implementation to use.
- Defaults to the first program found out of: `bison -y', `byacc',
- `yacc'.
- YFLAGS The list of arguments that will be passed by default to $YACC.
- This script will default YFLAGS to the empty string to avoid a
- default value of `-d' given by some make applications.
- CXXCPP C++ preprocessor
- Use these variables to override the choices made by `configure' or to help
- it to find libraries and programs with nonstandard names/locations.
- Report bugs to the package provider.
