--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--disable-shared don't provide a shared libgcc
+ --enable-vtable-verify Enable vtable verification feature
--enable-version-specific-runtime-libs Specify that runtime libraries should be installed in a compiler-specific directory
--enable-maintainer-mode
enable make rules and dependencies not useful (and
sometimes confusing) to the casual installer
+ --disable-largefile omit support for large files
--enable-decimal-float={no,yes,bid,dpd}
enable decimal float extension to C. Selecting 'bid'
or 'dpd' choses which decimal floating point format
to use
- --enable-sjlj-exceptions
- force use of builtin_setjmp for exceptions
+ --enable-explicit-exception-frame-registration
+ register exception tables explicitly at module
+ start, for use e.g. for compatibility with
+ installations without PT_GNU_EH_FRAME support
--enable-tls Use thread-local storage [default=yes]
Optional Packages:
--with-target-subdir=SUBDIR Configuring in a subdirectory for target
--with-cross-host=HOST Configuring with a cross compiler
--with-ld arrange to use the specified ld (full pathname)
+ --with-aix-soname=aix|svr4|both
+ shared library versioning (aka "SONAME") variant to
+ provide on AIX
--with-slibdir=DIR shared libraries in DIR LIBDIR
--with-build-libsubdir=DIR Directory where to find libraries for build system
--with-system-libunwind use installed libunwind
+ --with-glibc-version=M.N
+ assume GCC used with glibc version M.N or later
+ --with-gcc-major-version-only
+ use only GCC major number in filesystem paths
