How do I compile a C program with threads in gcc?

On Linux, you must first compile

gcc -g -Wall -pthread yourcode.c -lpthread -o yourprogram

      

        
        
        
      

    

<sup>-g

asks for debug information, -Wall

asks for all warnings, -pthread

asks for POSIX thread support.</sup>

when it compiles without warnings and you debug it with gdb

, you might want to optimize the compiler by replacing (or adding after) -g

to-O2

Very soon you will want to make your program out of several compilation units (linked together). Then you need to learn how to use a builder like GNU make and you will have Makefile

(don't forget the tabs are significant inside them).

You should of course use a source control system (I suggest using git , perhaps via gitorious or github ) in your source code.
