我正在尝试构建LIBVNCSERVER为共享库而不是可执行文件。构建 libVNCSERVER 的 make 文件是

include $(CLEAR_VARS)
LOCAL_PATH := $(INITIAL_PATH)
#for vnc
LIBVNCSERVER_ROOT:=./LibVNCServer-0.9.9
LIBVNCSERVER_SRC_FILES:= \
$(LIBVNCSERVER_ROOT)/libvncserver/main.c \
$(LIBVNCSERVER_ROOT)/libvncserver/rfbserver.c \
$(LIBVNCSERVER_ROOT)/libvncserver/rfbregion.c \
$(LIBVNCSERVER_ROOT)/libvncserver/auth.c \
$(LIBVNCSERVER_ROOT)/libvncserver/sockets.c \
$(LIBVNCSERVER_ROOT)/libvncserver/stats.c \

$(LIBVNCSERVER_ROOT)/libvncserver/rre.c \
$(LIBVNCSERVER_ROOT)/libvncserver/translate.c \
$(LIBVNCSERVER_ROOT)/libvncserver/cutpaste.c \
$(LIBVNCSERVER_ROOT)/libvncserver/httpd.c \
$(LIBVNCSERVER_ROOT)/libvncserver/cursor.c \
$(LIBVNCSERVER_ROOT)/libvncserver/font.c \
$(LIBVNCSERVER_ROOT)/libvncserver/draw.c \

$(LIBVNCSERVER_ROOT)/libvncserver/cargs.c \
$(LIBVNCSERVER_ROOT)/libvncserver/ultra.c \
$(LIBVNCSERVER_ROOT)/libvncserver/scale.c \
$(LIBVNCSERVER_ROOT)/libvncserver/zlib.c \

$(LIBVNCSERVER_ROOT)/common/vncauth.c \
$(LIBVNCSERVER_ROOT)/common/minilzo.c \
$(LIBVNCSERVER_ROOT)/common/zywrletemplate.c

LOCAL_CFLAGS  +=  -Wall \
                                -O3 \
                                -DLIBVNCSERVER_HAVE_ZLIB
LOCAL_C_INCLUDES += \
                                    $(LOCAL_PATH) \
                                    $(LOCAL_PATH)/$(LIBVNCSERVER_ROOT)/libvncserver \
                                    $(LOCAL_PATH)/$(LIBVNCSERVER_ROOT)/common \
                                    $(LOCAL_PATH)/$(LIBVNCSERVER_ROOT)/rfb \
                                    $(LOCAL_PATH)/$(LIBVNCSERVER_ROOT)/

LOCAL_MODULE    := myvnc
#for profiling
LOCAL_CFLAGS := -pg
#LOCAL_STATIC_LIBRARIES += android-ndk-profiler
LOCAL_ARM_MODE := arm  # remove this if you want thumb mode
LOCAL_SRC_FILES := $(LIBVNCSERVER_SRC_FILES)\
                vncmain.c
LOCAL_LDLIBS += -llog -lz -ldl -lpthread
LOCAL_ARM_NEON := true 
LOCAL_SHARED_LIBRARIES := libz
include $(BUILD_SHARED_LIBRARY)

__gnu_mcount_nc我从socket.c文件中得到未定义的引用。

从 CFLAGS 中删除 -pg，您不需要它来构建库，并且使用它生成的代码将比必要的稍慢。

如果您确实需要分析代码，则需要您自己的 __gnu_mcount_nc 实现。有关更多详细信息，请参阅
