为 Android 编译 VLC 时出现问题 - libvlcjni.so

Question

经过一天半的修改，我终于让 VLC 项目在 OS X 下几乎可以编译。当它即将链接 libvlcjni.so 时，我收到以下错误。大约还有 100 多个未定义的引用，但大多数都是少数函数：

std::__stl_throw_length_error(char const*) std::__node_alloc::_M_deallocate(void*, unsigned int)

有人指点吗？

编译拇指：vlcjni std::basic_string<char, std::char_traits<char>, std::allocator<char> >::_M_compare(char const*, char const*, char const*, char const*)': /Android/ndk/sources/cxx-stl/stlport/stlport/stl/_string.h:1076: undefined reference tostd::__stl_throw_out_of_range(char const*)'

尝试将这些行包含到您的 Application.mk 中：

APP_CPPFLAGS += -frtti 
APP_CPPFLAGS += -fexceptions

您必须明确启用 RTTI 和异常处理。

编辑（响应您的修改）：

# These are your lines in Application.mk
APP_PLATFORM := android-9
ifeq ($(NO_NEON),)
APP_ABI := armeabi-v7a
else ifneq ($(TEGRA2),)
APP_ABI := armeabi-v7a
else
APP_ABI := armeabi
endif

# Add these lines:
APP_CPPFLAGS += -frtti 
APP_CPPFLAGS += -fexceptions
#  I haven't seen them
