Note 1 C program development environment in Linux

------------------------------------- Chapter 1 C under Linux Program Development Environment Development Editor: Vim Compiler: select the gnu c/C ++ compiler GCC Debugger: GDB function library: Glibc system header file: glibc_headide kylix: dephikdeveloprhide under Linux: similar to Turbo C ++, the compiler is rarely used: gccgcc (GNU ccompiler) is a powerful and superior multi-platform compiler launched by GNU, the GCC compiler can compile and link source programs in C and C ++ into executable files. Below are the suffixes and explanations of some source files that GCC supports compiling. C is a suffix file, c Source code File. H is a suffix file. It is a program-contained header file //. I is a suffix file and is a pre-processed C source. Code File. A file with the suffix o is the compiled target file //. S is a file suffixed with GCC-O hello. c. Use GCC to compile our source program-O option. The intellectual file name output by the compiler is hellohello. C is our source program file-C option, indicating that we only require the compiler to output the target code, the-G option does not need to be output to indicate that the compiler is required to provide information for future debugging of the program during compilation. /Hello, you can see the program output result **************************** RPM package usage. to view the glibc version: ls/lib/libc-* view GCC version: GCC -- C program development process in versionlinux 1 use VI and other editing tools to compile the source program 2 save *. c3 uses GCC to compile binary executable files. 4. /. if there is a problem with out execution 5, you can use GDB for debugging // write a C program Hello. CINT main (INT argc, char ** argv) {printf ("Hello Linux \ n"); Return 0;} ls: displays files and folders in the current directory mkdir: create a folder CD folder name: Enter the folder
