How does the compilation process in C work?
The compiler checks the source code for the syntactical or structural errors, and if the source code is error-free, then it generates the object code. The c compilation process converts the source code taken as input into the object code or machine code.
What’s the difference between compilation and object code?
The compilation is a process of converting the source code into object code. It is done with the help of the compiler. The compiler checks the source code for the syntactical or structural errors, and if the source code is error-free, then it generates the object code.
How is the source code passed to the compiler?
Preprocessor The source code is the code which is written in a text editor and the source code file is given an extension “.c”. This source code is first passed to the preprocessor, and then the preprocessor expands this code. After expanding the code, the expanded code is passed to the compiler.
How is HELLO.C passed to the compiler?
Firstly, the input file, i.e., hello.c, is passed to the preprocessor, and the preprocessor converts the source code into expanded source code. The extension of the expanded source code would be hello.i. The expanded source code is passed to the compiler, and the compiler converts this expanded source code into assembly code.
Do you need to recompile a.so file?
So, if there’s any change in .so file, you don’t need to recompile your main program. But make sure that your main program is linked to the new .so file with ln command. This will help you to build the .so files.
How to stop the compilation process in GCC?
The assembler takes the IR code and transforms it into object code, that is code in machine language (i.e. binary). This will produce a file ending in “.o”. We can stop the compilation process after this step by using the option “-c” with the gcc command, and pressing enter.
