In section 1 of this chapter, what does the init function pointer passed by _ start point? By tracking the address, init actually points to the _ libc_csu_init function. This function is located in the CSU/Elf-init.c of the glibc source code directory. Let's take

returns a string that is inserted where the current command is located. The following is the built-in spec function: getenv getenv spec function with two parameters: an environment variable name and a string. If the environment variable is not defined, a critical error is generated. The return value is the value of the environment variable and the string is concatenated together. For example, if Topdir is defined as/path/to/top, then: %:getenv (Topdir/include) will be expanded i

with the compilation process, the compilation process is relatively simple. You can translate the compilation commands one by one based on the comparison table of the Assembly commands and machine commands. $ Gcc-c hello. c-o hello. o Or $ As hello. s-o hello. co Because the content of hello. o is a machine code, it cannot be viewed in the form of common text (if you open the vi, you will see garbled code ). 4.

Compile the script on the Internet and run it directly. The following is the script compilation process: 1. Install gmp according to steps 1 and 2 above, and so on; 2.

created by the operating system.The assembler generates the first type of target file. For the last two methods, some other processing is required. This is the work of The Link program.5. Link Program (Linking)The target file generated by the assembler cannot be executed immediately. There may be many unsolved problems. For example, a function in a source file may reference a symbol (such as a variable or function call) defined in another source file, or call a function in a library file in a p
