的Android NDK - 错误与建设ICU支持sqlite的时候

Question

我试图建立与Android NDK ICU支持sqlite的，在我的Android.mk我有以下几点：

SQLITE3_INCLUDE_DIRS := -I/home_folder/dev/platform_external_icu4c/common -I/home_folder/dev/platform_external_icu4c/i18n 

但是当我尝试编译我有一大堆undefined reference错误的：如libicuuc.a

Answer 1

你交的节目包括目录，但你在实际的ICU LIB连接（.a）中这样的文件？如果你的ICU有.mk或直接通过LOCAL_STATIC_LIBRARIES（甚至直接通过LOCAL_LDFLAGS），他们需要通过APP_MODULES在你的Application.mk中指定。

APP_MODULES的第一种方法是首选。
