1.移植环境：

• Ubuntu15.10 + arm-hisiv500-linux-
• glog-0.3.3 下载地址：https://code.google.com/archive/p/google-glog/downloads

2.移植glog：

1）解压

shunzhi@ubuntu:~/software$ tar -xvzf glog-0.3.3.tar.gz

2）新建一个安装目录

shunzhi@ubuntu:~/software$ cd glog-0.3.3/  
shunzhi@ubuntu:~/software/glog-0.3.3$ mkdir _install  

3）配置编译环境变量

shunzhi@ubuntu:~/software/glog-0.3.3$ ./configure --host=arm-hisiv500-linux --prefix=/home/shunzhi/software/glog-0.3.3/_install/  

4）编译glog库

shunzhi@ubuntu:~/software/glog-0.3.3$ make
shunzhi@ubuntu:~/software/glog-0.3.3$ make install

5）安装glog库

shunzhi@ubuntu:~/software/glog-0.3.3$ cd _install/
shunzhi@ubuntu:~/software/glog-0.3.3/_install$ ls
include  lib  share
然后将lib目录中的libglog.so.0文件拷贝到3519开发板的/usr/lib目录下。

3.测试：

1）测试程序
glog_hisi.c

    #include <stdio.h>
    #include <iostream>
    #include <sys/stat.h>
    #include <sys/types.h>
    #include <glog/logging.h>
    #include <glog/log_severity.h>

    int main(void)
    {
        char defpath[100] = "./log";
        //创建log文件夹
        mkdir("./log",0777);
        //log初始化
        google::InitGoogleLogging("New");

        FLAGS_colorlogtostderr = true;//设置输出到屏幕的日志显示相应颜色
        //FLAGS_servitysinglelog = true;// 用来按照等级区分log文件
        FLAGS_logbufsecs = 0;//缓冲日志输出，默认为30秒，此处改为立即输出
        FLAGS_max_log_size = 1; //最大日志大小为 100MB
        FLAGS_stop_logging_if_full_disk = true;//当磁盘被写满时，停止日志输出
        google::SetStderrLogging(google::GLOG_INFO); //设置级别 高于 google::INFO 的日志同时输出到屏幕

        //日志名称和输出地址
        char Info[50] = {0};
        char Warn[50] = {0};
        char Error[50] = {0};
        char Fatal[50] = {0};

        strcpy(Info, defpath);
        strcpy(Warn, defpath);
        strcpy(Error, defpath);
        strcpy(Fatal, defpath);

        strcat(Info, "/Info_");
        strcat(Warn, "/Warning_");
        strcat(Error, "/Error_");
        strcat(Fatal, "/Fatal_");
        google::SetLogDestination(google::GLOG_INFO,Info); 
        google::SetLogDestination(google::GLOG_WARNING,Warn); 
        google::SetLogDestination(google::GLOG_ERROR,Error); 
        google::SetLogDestination(google::GLOG_FATAL,Fatal); 
        LOG(INFO) <<"------------------------------"<<std::endl;
        LOG(INFO) <<"---------Creat Log!!!---------\n ";
        LOG(INFO) <<"------------------------------"<<std::endl;

        return 1;
    }

Makefile

    CC = arm-hisiv500-linux-g++
    #CC = g++

    DEMOTAR = glog_hisi
    DEMOOBJ = glog_hisi.o

    CFLAGS += -mcpu=cortex-a7 -mfloat-abi=softfp -mfpu=neon-vfpv4 -mno-unaligned-access -fno-aggressive-loop-optimizations
    CFLAGS += -g -Wall -I/home/shunzhi/software/glog-0.3.3/_install/include
    LDFLAGS += -L/home/shunzhi/software/glog-0.3.3/_install/lib -Wl,-Bdynamic -lglog -lpthread -lrt

    %.o: %.c
        @echo "[Compiling] $< ..."
        @$(CC) $(CFLAGS) -c $<

    all: $(DEMOTAR)

    $(DEMOTAR):$(DEMOOBJ)
        @$(CC) -o $@ $^ $(LDFLAGS)

    .PHONY : clean
    clean:
        rm -rf $(DEMOOBJ) $(DEMOTAR)  

2）编译测试程序

shunzhi@ubuntu:~/workspace/glog$ ls
glog_hisi.c  Makefile
shunzhi@ubuntu:~/workspace/glog$ make
[Compiling] glog_hisi.c ...
shunzhi@ubuntu:~/workspace/glog$ ls
glog_hisi  glog_hisi.c  glog_hisi.o  Makefile
shunzhi@ubuntu:~/workspace/glog$ 

3）测试结果

~/glog # ls
glog_hisi
~/glog # ./glog_hisi 
I0101 15:44:54.473941   273 glog_hisi.c:46] ------------------------------
I0101 15:44:54.475924   273 glog_hisi.c:47] ---------Creat Log!!!---------

I0101 15:44:54.476441   273 glog_hisi.c:48] ------------------------------
~/glog # ls
glog_hisi  log

注：log文件就是生成的日志文件

4.移植库可能遇到的问题

1）执行congfigure配置通过，而且执行make编译也正常，在执行sudo make install是出现了下面的错误：

错误log

make[1]: Entering directory '/home/shunzhi/software/glog-0.3.3'
test -z "/home/shunzhi/software/glog-0.3.3/lib" || /bin/mkdir -p "/home/shunzhi/software/glog-0.3.3/lib"

make[1]: Leaving directory '/home/shunzhi/software/glog-0.3.3'
Makefile:1428: recipe for target 'install-am' failed
make: *** [install-am] Error 2

错误原因：
是由于环境变量设置的不对，我们交叉工具链root用户下找不到。

解决方案：
按照上述我的配置步骤，新建一个安装目录（shunzhi@ubuntu:~/software/glog-0.3.3$ mkdir _install），然后配置选项中指明安装目录（--prefix=/home/shunzhi/software/glog-0.3.3/_install/），执行make install即可。
