- \`configure' configures llvm 2.6 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]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
- --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
- --infodir=DIR info documentation [DATAROOTDIR/info]
- --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
- --mandir=DIR man documentation [DATAROOTDIR/man]
- --docdir=DIR documentation root [DATAROOTDIR/doc/-llvm-]
- --htmldir=DIR html documentation [DOCDIR]
- --dvidir=DIR dvi documentation [DOCDIR]
- --pdfdir=DIR pdf documentation [DOCDIR]
- --psdir=DIR ps documentation [DOCDIR]

- --with-udis86=<path> Use udis86 external x86 disassembler library
- --with-oprofile=<prefix>
- Tell OProfile >= 0.9.4 how to symbolize JIT output
- 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>
- CPPFLAGS C/C++/Objective 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
- CXXCPP C++ preprocessor
- F77 Fortran 77 compiler command
- FFLAGS Fortran 77 compiler flags
- 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 <llvmbugs@cs.uiuc.edu>.
