为Android编译libnice

我试图为Android编译libnice（具体来说是v0.18），但遇到了一些麻烦。如何为Android编译libnice？我在下面列出了我迄今为止的尝试

第一次尝试

我的第一次尝试是使用一个定制的Android.mk makefile，但我得到了一个错误，指出

AI_numericost undeclared

（添加

#include

并没有解决这个问题，我在这里没有想法）。请参阅下面的my Android.mk

LOCAL_PATH  := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE        := glib
LOCAL_SRC_FILES     := lib/libglib-2.0.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE        := gobject
LOCAL_SRC_FILES     := lib/libgobject-2.0.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)

LOCAL_SRC_FILES     := lib/libgmodule-2.0.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE        := gio
LOCAL_SRC_FILES     := lib/libgio-2.0.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)

LOCAL_SRC_FILES     := lib/libgthread-2.0.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE        := ffi
LOCAL_SRC_FILES     := lib/libffi.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE        := iconv
LOCAL_SRC_FILES     := lib/libiconv.a

include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE        := z
LOCAL_SRC_FILES     := lib/libz.a
include $(PREBUILT_STATIC_LIBRARY)


include $(CLEAR_VARS)
NICE                := libnice-0.1.8
LOCAL_MODULE        := ice_jni
LOCAL_LDLIBS        := -llog 

LOCAL_STATIC_LIBRARIES  := glib gobject gmodule gio gthread ffi iconv intl xml2 z 

NICE_INCLUDES       := $(LOCAL_PATH)/include \
                        $(LOCAL_PATH)/lib/glib-2.0/include \
                        $(LOCAL_PATH)/lib/libffi-3.0.13/include \
                        $(wildcard $(LOCAL_PATH)/include/*) \
                        $(LOCAL_PATH)/$(NICE)/nice \
                        $(LOCAL_PATH)/$(NICE)/agent \
                        $(LOCAL_PATH)/$(NICE)/random \
                        $(LOCAL_PATH)/$(NICE)/socket \
                        $(LOCAL_PATH)/$(NICE)/stun

NICE_SRC            := $(patsubst $(LOCAL_PATH)/%, %, $(wildcard $(LOCAL_PATH)/$(NICE)/agent/*.c)) \
                        $(patsubst $(LOCAL_PATH)/%, %, $(wildcard $(LOCAL_PATH)/$(NICE)/random/*.c)) \
                        $(patsubst $(LOCAL_PATH)/%, %, $(wildcard $(LOCAL_PATH)/$(NICE)/socket/*.c)) \
                        $(patsubst $(LOCAL_PATH)/%, %, $(wildcard $(LOCAL_PATH)/$(NICE)/stun/*.c))

LOCAL_C_INCLUDES        := $(LOCAL_PATH) \
                            $(NICE_INCLUDES)

LOCAL_SRC_FILES         := ICE.cpp \
                            $(NICE_SRC)

include $(BUILD_SHARED_LIBRARY)

静态库是从gstreamer 1.4.1调试版本复制过来的，并根据以下所述进行选择

第二次尝试

然后，我尝试编译一个引用的静态库，这再次导致了问题：

export PKG_CONFIG_PATH=`pwd`/../gstreamer/lib/pkgconfig  
export CFLAGS="--sysroot=`pwd`/../toolchain/sysroot"
./configure --prefix=`pwd`/../build --host=arm-linux-androideabi

这将导致以下错误。将

-mthumb

或

-marm

添加到CFLAGS会导致

C编译器在配置期间无法创建可执行文件

错误

stunagent.c: Assembler messages:
stunagent.c:160: Error: no such instruction: `rev %eax,%eax'
stunagent.c:676: Error: no such instruction: `rev16 %ax,%ax'

上面提到的行不包含ASM，而是调用

htons

和

ntohl

，所以我想我做错了什么

我使用NDK中的

make_standalone_工具链

，使用各种Android版本创建工具链

有人能帮忙吗？提前谢谢！

---

~

终于！这花了我太长时间。问题是libnice在configure期间创建了一个

config.h

文件，该文件定义了一些宏（

HAVE\u NETDB\u h

）。虽然我不能用我的工具链编译libnice，但我能够生成一个有效的config.h，我可以使用它。在此之后，我不得不对我的

Android.mk

做一些额外的调整。我将在下面为其他人发布这两个文件以搜索答案

（注意：您仍然需要glib。由于我的项目使用gstreamer，所以我能够使用由包含glib的gstreamer构建脚本创建的共享库。）

干杯
