Linking a C program to MySQL

Linking a C program to MySQL

Linking a C program to MySQL

I am compiling a C program and then trying to link it with the command:

gcc -g  url.cc url.o  -lm -L/usr/lib/mysql -lmysqlclient

Once I enter the above command, I get an error that looks like

url.o(.text+0x0): multiple definition of `PrintHTMLHeader(void)'
where url.o is my object file ... and PrintHTMLHeader is some function ...

I am getting this error for every function that I have defined ...

Could you tell me what is wrong?


RE: Linking a C program to MySQL

Is url.o an object file produced from url.cc? If so, you shouldn't be compiling both at the same time like that -- you're probably getting the multiple definition error because your functions are defined in both url.cc and url.o. Try:

gcc -g  url.cc -lm -L/usr/lib/mysql -lmysqlclient


gcc -g  url.o -lm -L/usr/lib/mysql -lmysqlclient

Is this a C or a C++ program? If it's a C program the source file suffix should be .c instead of .cc
