Build libc++ static w/o hidden visibility
This is to fix issue with error message reads: .../ld: warning: hidden symbol 'snprintf' in prebuilts/ndk/current/sources/cxx-stl/llvm-libc++/libs/armeabi-v7a/libc++_static.a(snprintf.o) is referenced by DSO out/target/product/hammerhead/obj/lib/libcutils.so There is only one copy of libc++ libraries for all API levels with various degree of libc/libm support, the reason why libc++ libraries links with android_support.a which contains missing libc/libm functions (including snprintf) needed by libc++ in API 3. Since https://android-review.googlesource.com/#/c/103261 all support functions in libc++ are built with hidden visibility, otherwise other libraries may use snprintf from libc++ instead of libc.so. Unfortunately unlike shared library it's not possible to hide hidden symbol from linker, and causes warning message you just read. This CL compile libc++ with --visible-static to restore previous behavior. Also see https://android-review.googlesource.com/#/c/123340 Affected functions are std::__1::__snprintf_l(char*, unsigned int, locale_struct*, char const*, ...) vsnprintf_l snprintf_l vsnprintf snprintf Change-Id: I8b4409ca7c59eed4018acd3a9e38970074d206cb
