MAKE for Android OS source code fails

Question

I'm trying to build a custom ROM for Android. Currently, I've setup my build environment and downloaded the source code.

I'm following instructions at https://source.android.com/source/building#build-the-code

Everything works while executing source build/envsetup.sh and lunch , but errors arise when executing make :

external/libcxx/include/cmath:679:9: note: using declaration
using ::acos;
        ^
external/libcxx/include/cmath:684:46: error: declaration conflicts with target of using declaration already in scope
inline _LIBCPP_INLINE_VISIBILITY long double acos(long double __lcpp_x) _NOEXCEPT {return acosl(__lcpp_x);}
                                             ^

Answer 1

It seems that it is caused by xcode 9. see https://forums.developer.apple.com/thread/87814 . I encounted this problem too. I plan to switch to xcode 8.3. I had compiled android 7.1.2 with xcode 8.3 and sdk 10.11, that was ok, no problem.
