我正在尝试从jni文件夹中的netguard本机库创建一个.so文件，但是在执行“ ndk-build”后出现此错误“ collect2 ld返回了1个退出状态”。请我希望有人帮助创建一个.so文件。
项目路径：https://github.com/M66B/NetGuard
我的Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
APP_PROJECT_PATH := /home/mishael/AndroidStudioProjects/NetGuard/app/src/main/jni/netguard/
APP_PLATFORM=android-14
APP_ABI := armeabi armeabi-v7a x86 mips
LOCAL_MODULE := netguard
LOCAL_SRC_FILES := netguard.c
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)

最佳答案
NetGuard Android Studio项目中集成了构建NetGuard本机代码的功能，因此我想您正在使这一过程变得更加困难。
