It's an 'experimental' feature, so you have to enable EXPERIMENTAL in the
"Paths and Misc. options" sub-menus. Support for gcc-4.7.0 is very new, so
be prepared for breakage. If you are new to cross-compilation, you might
prefer starting off a more stable version, such as gcc-4.6.3
Also, you can search symbols in the menuconfig by hitting the '/' key and
enter part of a symbol's name. Then, you can see the dependencies of that
symbol.
For example looking at the gcc-4.6.3 help, I can see that the associated
symbol is CC_V_4_6_3. So, for gcc-4.7.0, I would conclude that the symbol
would be CC_V_4_7_0. Let's hit '/' and enter that in the search box:
Symbol: CC_V_4_7_0 [=n]
Type : boolean
Prompt: 4.7.0 (EXPERIMENTAL)
Defined at config/cc/gcc.in:45
Depends on: <choice> && EXPERIMENTAL [=n]
Location:
-> C compiler
-> gcc version (<choice> [=y])
Selects: CC_GCC_4_7 [=n]
So, I can see that gcc-4.7.0 depends on EXPERIMENTAL. Where's that defined?
Let's see:
Symbol: EXPERIMENTAL [=n]
Type : boolean
Prompt: Try features marked as EXPERIMENTAL
Defined at config/global/ct-behave.in:18
Location:
-> Paths and misc options
Regards,
Yann E. MORIN.
