Makefile Learning under Linux

1. Basic Concepts

About compiling and linking the program:
Compiling links
SOURCE------Intermediate Code------executable file
. C. o
During the compilation process, the main check syntax is correct, function and variable declaration is correct, if the function is not declared, the compiler will give a warning, but can generate obj file;
Link, the main link function and global variables, is responsible for managing the intermediate target file, looking for the implementation of the function, if not found, Report link error code.
In most cases, due to the large number of source files, there are too many intermediate target files generated by the compilation, too many intermediate target files to be pointed at the link, which is inconvenient for compiling,
So the intermediate target file can be a package, window under the name of the library file, that is,. lib file, Unix, is the archive file, which is. a files.
