- assert,df,fold,gc,gcac,gimple,misc,
+ assert,df,extra,fold,gc,gcac,gimple,misc,
rtlflag,rtl,runtime,tree,valgrind,types
--enable-coverage[=LEVEL]
enable compiler's code coverage collection. Use to
package
--enable-tls enable or disable generation of tls code overriding
the assembler check for tls support
+ --enable-vtable-verify enable vtable verification feature
--enable-objc-gc enable the use of Boehm's garbage collector with the
GNU Objective-C runtime
--disable-shared don't provide a shared libgcc

--enable-gnu-unique-object
enable the use of the @gnu_unique_object ELF
extension on glibc systems
--enable-linker-build-id
compiler will always pass --build-id to linker
+ --enable-default-ssp enable Stack Smashing Protection as default
--enable-maintainer-mode
enable make rules and dependencies not useful (and
sometimes confusing) to the casual installer
--enable-host-shared build host code as shared libraries
--disable-libquadmath-support
disable libquadmath support for Fortran
+ --enable-default-pie enable Position Independent Executable as default
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-build-libsubdir=DIR Directory where to find libraries for build system
--with-local-prefix=DIR specifies directory to put local include
+ --with-native-system-header-dir=dir
+ use dir as the directory to look for standard
+ system header files in. Defaults to /usr/include.
+ --with-build-sysroot=sysroot
+ use sysroot as the system root during the build
+ --with-sysroot[=DIR] search for usr/lib, usr/include, et al, within DIR
--with-gxx-include-dir=DIR
specifies directory to put g++ header files
--with-cpp-install-dir=DIR
--with-as arrange to use the specified as (full pathname)
--with-stabs arrange to use stabs instead of host debug format
--with-dwarf2 force the default debug format to be DWARF 2
- --with-native-system-header-dir=dir
- use dir as the directory to look for standard
- system header files in. Defaults to /usr/include.
- --with-build-sysroot=sysroot
- use sysroot as the system root during the build
- --with-sysroot[=DIR] search for usr/lib, usr/include, et al, within DIR
--with-specs=SPECS add SPECS to driver command-line processing
--with-pkgversion=PKG Use PKG in the version string in place of "GCC"
--with-bugurl=URL Direct users to URL to report a bug
--with-gnu-ld assume the C compiler uses GNU ld default=no
--with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
--without-libiconv-prefix don't search for libiconv in includedir and libdir
+ --with-gcc-major-version-only
+ use only GCC major number in filesystem paths
--with-pic try to use only PIC/non-PIC objects [default=use
both]
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
you have headers in a nonstandard directory <include dir>
