cat <<EOF
Usage: $0 [OPTION]... [TARGET]
Defaults for the options are specified in brackets.
System types:
--target=TARGET configure to run on target TARGET [detected]
--host=TARGET same as --target
Installation directories:
--prefix=PREFIX main installation prefix [/]
--exec-prefix=EPREFIX installation prefix for executable files [PREFIX]
Fine tuning of the installation directories:
--dynlibdir=DIR shared library files [PREFIX/lib]
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR admin executables [EPREFIX/sbin]
--libexecdir=DIR package-scoped executables [EPREFIX/libexec]
--libdir=DIR static library files [PREFIX/lib/$package]
--includedir=DIR C header files [PREFIX/include]
--datadir=DIR global configuration files [PREFIX/etc]
If no --prefix option is given, by default libdir (but not dynlibdir) will be
/usr/lib/$package, and includedir will be /usr/include.
Dependencies:
--with-sysdeps=DIR use sysdeps in DIR [PREFIX/lib/skalibs/sysdeps]
--with-include=DIR add DIR to the list of searched directories for headers
--with-lib=DIR add DIR to the list of searched directories for static libraries
--with-dynlib=DIR add DIR to the list of searched directories for shared libraries
If no --prefix option is given, by default sysdeps will be fetched from
/usr/lib/skalibs/sysdeps.
Optional features:
--enable-shared build shared libraries [disabled]
--disable-static do not build static libraries [enabled]
--disable-allstatic do not prefer linking against static libraries [enabled]
--enable-static-libc make entirely static binaries [disabled]
--enable-slashpackage[=ROOT] assume /package installation at ROOT [disabled]
--enable-cross=CROSS prefix toolchain executable names with CROSS [none]
