Question

我试图在jni文件夹中从netguard本机库创建一个.so文件，但是我收到此错误＆＃34; collect2 ld返回1退出状态＆＃34;在我执行＆＃34; ndk-build＆＃34;之后。我希望有人帮助创建一个.so文件。

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)

错误消息

构建NetGuard本机代码已集成在NetGuard Android Studio项目中，因此我猜您正在使其变得更加困难。

构建ndk库时出错
