未定義參考的問題NDK

Question

好吧我知道這已經提出來了。但我的似乎沒有解決。 在我們開始讓人們知道以下幾點：

• OS：Win7的（X86）
• IDE：Eclipse的朱諾（4.2）
• NDK：R8E
• 的Android API：17（果凍豆4.2 ）

我想讓SDL_ttf完全編譯。我只是試圖建立這個項目並繼續開展工作，並且經過很多努力才意識到某些文件確實存在於他們所說的存在的地方。現在我越來越

問題是這樣的：

FIND: Parameter format not correct 

所以FreeType的未編譯。

您正在Windows中構建，因此正在執行的find命令是Windows版本，它具有不同的語法。

您需要下載一個find程序，它具有與unix相同的語法。 例如從這裏： http://unxutils.sourceforge.net/

然後，你需要強制FreeType的Android.mk使用新find：

變化：

APP_SUBDIRS := $(patsubst $(LOCAL_PATH)/%, %, $(shell find $(LOCAL_PATH)/src -type d)) 

到

APP_SUBDIRS := $(patsubst $(LOCAL_PATH)/%, %, $(shell PATH_TO_UNIXLIKE_FIND\find $(LOCAL_PATH)/src -type d)) 

例如

APP_SUBDIRS := $(patsubst $(LOCAL_PATH)/%, %, $(shell c:\unixtools\usr\local\wbin\find $(LOCAL_PATH)/src -type d))
