--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-version-specific-runtime-libs Specify that runtime libraries should be installed in a compiler-specific directory
- --enable-objc-gc enable the use of Boehm's garbage collector with
- the GNU Objective-C runtime.
--enable-multilib build many library versions (default)
--enable-maintainer-mode enable make rules and dependencies not useful
(and sometimes confusing) to the casual installer
optimize for fast installation [default=yes]
--disable-libtool-lock avoid locking (might break parallel builds)
--enable-tls Use thread-local storage [default=yes]
- --enable-sjlj-exceptions
- force use of builtin_setjmp for exceptions
+ --enable-objc-gc enable use of Boehm's garbage collector with the GNU
+ Objective-C runtime
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--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]
+ --with-target-bdw-gc=PATHLIST
+ specify prefix directory for installed bdw-gc
+ package. Equivalent to
+ --with-target-bdw-gc-include=PATH/include plus
+ --with-target-bdw-gc-lib=PATH/lib
+ --with-target-bdw-gc-include=PATHLIST
+ specify directories for installed bdw-gc include
+ files
+ --with-target-bdw-gc-lib=PATHLIST
+ specify directories for installed bdw-gc library
+ --with-gcc-major-version-only
+ use only GCC major number in filesystem paths
