Mysql-arm-linux-gcc Compilation error: libc. soformatnotrecognized.

I am a newbie and have never touched arm development before. I have encountered difficulties in completing the two-day design. please help me to read it and thank you first! My Development Board is a lab Gateway (HBE-UBI-box2) that collects information from sensors. Compile the compiled C file into a cgi file through the arm-linux-gcc compiler (Compile Command: arm-linux-gcc-oinfo.cgiinfo.c) info. c is the file I wrote. After compilation, it is uploaded to the gateway. then you can access the gateway to see the program implementation result. However, the mentor said a few days ago that the Gateway cannot support a large amount of access at the same time. I want to upload the sensor data collected by the gateway to the mysqlarmarm development board of the lab.

New to me, I have never touched on arm development before. I have encountered difficulties in completing the design in the past two days. please take a look,
Thank you!
My Development Board is a lab Gateway (HBE-UBI-box2) that collects information from sensors. Compile the compiled C file into a cgi file through the arm-linux-gcc compiler (Compile Command: arm-linux-gcc-o info. cgi info. c) info. c is the file I wrote. After compilation, it is uploaded to the gateway. then you can access the gateway to see the program implementation result.
However, a few days ago, the mentor said that the Gateway cannot support a large amount of access at the same time. I want to upload the sensor data collected by the gateway to the laboratory server, and then write a website to access the data on the server... Well, I dare not resist either. I have built a MySQL database on the server and written several JSPS to access the database.
However, it is difficult to transmit data from the gateway to the server. At the beginning, I thought it was very simple.
This code is added to the code that does not connect to the mysql database:
Int connmysql (){

      MYSQL mysql, *sock;        mysql_init(&mysql);      if (!(sock = mysql_real_connect(&mysql, "XXX", "XXX", "XXX", "XXX", 0, NULL, 0)))      {      printf("Cannot connect to database:%s\n",mysql_error(sock));      return 0;      }  

Char sqlbuf [200] = "insert into sensordata VALUES ('0', 'sstatus. ID', 'sstatus. illumi', 'sstatus. temp ', 'sstatus. humid', 'sstatus. battery ');";

   if (mysql_query(sock, sqlbuf))     {      printf("Query Failed:%s", mysql_error(sock));      return 0;     }     mysql_close(sock);return 0;

}

Among them, the IP address in the database connection statement and the user name and password are correct. I replaced it with XXX ~...

The code is also written, but I reported an error when compiling it with arm-linux-gcc-o. Baidu found it too simple. As instructed by others, mysql clients and servers are installed on the Ubuntu virtual machine.
1. sudo apt-get install mysql-server
2. apt-get install mysql-client
3. sudo apt-get install libmysqlclient-dev
Many compilation commands have been found. The path of the library used for compilation should be added. The final command is as follows: arm-linux-gcc-I '/usr/include/mysql'-L'/usr/lib/i386-linux-gnu '-lmysqlclient-lpthread-lz-lm-lrt-ldl-o info. cgi mysql-info.c.
At this time, the nightmare started. at the beginning, I reported a lot of errors, so I had to troubleshoot them one by one. The bitterness was not shown yet, but there was still a problem that could not be solved:

The error message is: the file format of libc. so is not recognized and parsed incorrectly. I haven't found the libc suitable for arm programming for a long time. so files can only be used for help. if you have a solution or have a new idea for the idea of this project (that is, you can implement the same function without connecting to mysql through arm) thank you for your advice ~
