#fatal error mysql.h

本文介绍了在尝试编译包含MySQL客户端版本打印代码时遇到的找不到mysql.h文件的问题，并提供了几种解决方案，包括检查mysql.h文件的存在位置、使用mysql_config工具、安装缺失的开发包等。

问题

I have the following code

#include

int main(int argc, char **argv)

{

printf("MySQL client version: %s\n", mysql_get_client_info());

exit(0);

}

when i try to compile it using

gcc mysqldb.c -o mysql -I/usr/include/mysql -lmysqlclient

i get an error saying fatal error mysql.h:No such file or directory. how can i successfully compile and run the code

回答1:

Check that /usr/include/mysql/mysql.h exists. If you have installed the header files somewhere else (say /opt/mysql/include), add that location with -I/opt/mysql/include.

回答2:

I do not know if there is some variation in your operation system. Mine is Arch Linux, and I have installed mariaDB. Within the package, there is a program called 'mysql_config' which can provide the right way of compile your program. By runnig

$ mysql_config --help

Usage: /usr/bin/mysql_config [OPTIONS]

Options:

--cflags [-I/usr/include/mysql]

--include [-I/usr/include/mysql]

--libs [-L/usr/lib -lmysqlclient -lpthread -lz -lm -lssl -lcrypto -ldl]

--libs_r [-L/usr/lib -lmysqlclient_r -lpthread -lz -lm -lssl -lcrypto -ldl]

--plugindir [/usr/lib/mysql/plugin]

--socket [/run/mysqld/mysqld.sock]

--port [0]

--version [10.0.17]

--libmysqld-libs [-L/usr/lib -lmysqld]
