爲Android編譯VLC的問題 - libvlcjni.so

Question

經過一天半的修改，我終於得到了VLC項目，幾乎可以在OS X下編譯。當它剛剛鏈接libvlcjni.so時，出現以下錯誤。大概有100多個未定義的引用，但多數是一些功能：

的std :: __ stl_throw_length_error（字符常量*） 的std :: __ node_alloc :: _ M_deallocate（void *的，無符號整型）

有沒有人有任何指針？

嘗試包括這些行到您的Application.mk：

APP_CPPFLAGS += -frtti 
APP_CPPFLAGS += -fexceptions 

你必須明確地啓用RTTI和異常處理。

EDIT（回答您的修改）：

# 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
