I’ve compiled fine under QNX with

cc -o test $(mysql_config –cflags) test.c $(mysql_config –libs)

be sure your dev libraries are installed, Jesus your code shows some weird characters ->> âprintfâ

Best Regards

pleased

I’m compiling as follows:

gcc -o jesus $(/usr/local/src/inser_m_c/mysql/bin/mysql_config –cflags) jesus.c $(/usr/local/src/inser_m_c/mysql/bin/mysql_config –libs)

It has an error

jesus.c: In function âmainâ:
jesus.c:25: warning: passing argument 1 of âprintfâ from incompatible pointer type
jesus.c:31: warning: passing argument 1 of âprintfâ from incompatible pointer type
/usr/bin/ld: cannot find -lmysql
collect2: ld returned 1 exit status

Thanks for your help

From my previous post, the include file is stdlib.h…

Might be good to add another include file #include to handle the exit(1) func properly without warnings from the compiler.

There is alway a security risk to hard code values from within your code. If you run from the shell $ strings output-file you would be able to see the user credentials along with other data. If you reverse engineer an executable, that would be pretty much step-1. A good exercise to modify the code to enter data from stdin. gets(something) or fgets(something sizeof(something), stdin)… string.h

ok creating a symlink to /opt/lampp/mysql/mysql.sock from /var/run/mysqld/mysqld.sock solved the problem.
Thank you for the article, it was really helpful.

I have Lampp installed. When I run mysql_config –libs I was asked to install ‘libmysqlclient15-dev’. When I run mysql_config command with libs and cflags after installing libmysqlclient15-dev it didn’t give me the exact output as you have specified but -L/usr/lib/mysql -lmysqlclient and -I/usr/include/mysql was there respectively.
Program compilation was done successfully with few warnings but when I run it, gave me following error.
Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)
what might be the problem?
