我有一个用于构建 libpng 的简单 Android.mk 文件,我从 AOSP 获取并稍作修改以构建共享库而不是静态库。

  LOCAL_PATH:= $(call my-dir)
  LOCAL_CFLAGS := 
  LOCAL_COPY_HEADERS_TO := libs/include
  LOCAL_COPY_HEADERS := \
     png.h \
     pngconf.h \
     pngusr.h

  LOCAL_SRC_FILES := \
     png.c \
     pngerror.c \
     pnggccrd.c \
     pngget.c \
     pngmem.c \
     pngpread.c \
     pngread.c \
     pngrio.c \
     pngrtran.c \
     pngrutil.c \
     pngset.c \
     pngtrans.c \
     pngvcrd.c \
     pngwio.c \
     pngwrite.c \
     pngwtran.c \
     pngwutil.c

  LOCAL_LDLIBS := -lz

  LOCAL_MODULE := png
  LOCAL_MODULE_FILENAME := libpng

  include $(BUILD_SHARED_LIBRARY)

LOCAL_COPY_HEADERS_TO 和 LOCAL_COPY_HEADERS 选项似乎应该将指定的标头复制到 libs/include 目录......但它们什么都不做。该库本身似乎构建正确。我正在为 ndk-build 使用详细输出并且没有错误。这是我使用的命令(我只是添加了转义符,因此命令更易于阅读):

ndk-build \
NDK_PROJECT_PATH=. \
APP_BUILD_SCRIPT=Android.mk \
TARGET_ARCH_ABI=armeabi-v7a \
TARGET_PLATFORM=android-9 \
V=1 NDK_LOG=1 -B

这是构建输出。请注意,最后 install 仅在 lib 二进制文件上调用。

你搞砸了你的订单。你应该有:

LOCAL_COPY_HEADERS := \
     png.h \
     pngconf.h \
     pngusr.h

其次是:

LOCAL_COPY_HEADERS_TO := libs/include

(您必须指定您的标头,然后告诉系统将它们复制到哪里。)它也可能在您当前的 sdk 上已被弃用。
