Question

经过一天半的修改后，我终于得到了VLC项目，几乎在OS X下编译。当它即将链接libvlcjni.so时，我得到以下错误。还有大约100个未定义的引用，但大多数是很少的函数：

std :: __ stl_throw_length_error（char const *） std :: __ node_alloc :: _ M_deallocate（void *，unsigned int）

有没有人有任何指示？

尝试将这些行包含在Application.mk中：

APP_CPPFLAGS += -frtti 
APP_CPPFLAGS += -fexceptions

您必须明确启用RTTI和Exceptions处理。

编辑（对您的修改的回应）：

# 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
