Question

我无法包含Android NDK本机库zlib标头 zlib.h ：我收到*致命错误：

zlib.h：没有这样的文件或目录

运行mka hello_world时

。

我正在使用CyanogenMod mka build命令编译（这是Android NDK）。

Android.mk档案：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS) 
LOCAL_SRC_FILES := test.c
LOCAL_MODULE      := hello_world  
LOCAL_LDLIBS      := -lz
include $(BUILD_EXECUTABLE)

test.c（此处不需要zlib，但这是示例）：

#include <sys/types.h>
#include <stdio.h>
#include <stdlib.h>
#include <zlib.h>
int main()
{
     printf("Hello World\n");
     return 0;
}

解决方法是使用编译zlib共享库，但为什么我应该这样做，因为它应该是标准的＆＃34;稳定＆＃34; NDK库！

注意this没有帮助：

是的，对不起，但这确实是NDK构建中的一个错误   脚本。现在，您可以替换：

LOCAL_LDLIBS := -lz

与

LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -lz
     抱歉，这将在下一个NDK版本中修复。

Answer 1

看来这是一个错误。我们需要通过构建和包含android_external_zlib来使用解决方法。如果最终使用CyanogenMod构建系统，我的模块Android.mk中添加了这些：

LOCAL_C_INCLUDES    += $(LOCAL_PATH)/../zlib/src
LOCAL_SHARED_LIBRARIES  += libz

但是对于这个问题的大量观众（3k +观看次数），有人应该发布基于Android NDK的完整解决方案。

Answer 2

您可能缺少zlib头文件，请尝试安装libz-dev开发包，例如。

sudo apt-get install libz-dev

Android NDK - 致命错误：zlib.h：没有这样的文件或目录
