GCC compilers

GCC hello.c-o Hello #将hello. c compiled into a hello executable file

GCC-E hello.c-o hello.i #将hello. C converted to a preprocessed file hello.i
Gcc-s hello.c-o Hello. S #将hello. C converted to assembly file hello. S
Gcc-c hello.c-o hello.o #将hello. C converted to binary file hello.o
Gcc-i dir hello.c-o Hello #-I followed by path, specifying the dir path to find the header file

Gcc-wall Hello.c-o Hello #显示编译过程中所有的警告信息

Gcc-g hello.c-o Hello #带调试信息的程序, can be debugged with GDB

Gcc-v hello.c-o Hello #显示执行编译阶段的命令. Display compiler driver, preprocessor, compiler version number at the same time
Gcc-nostdinc-i dir hello.c-o Hello #不要在标准系统目录中寻找头文件. Search only the directory specified by the '-I ' option (and the current directory)

compile static link library
gcc-c Hello.c-o hello.o                       #先生成目标文件 . o  
GCC cxd.c-o cxd-l/root/desktop/hello.a          & nbsp     #调用自己的静态链接库

compiling dynamic-link libraries
gcc-fpic-c hello.c                              # Compiles a location-independent. o File

gcc-shared Hello.o-o hello.so #生成动态链接库

GCC cxd.c-o cxd-l/root/desktop/hello.so #调用自己的动态链接库

GDB Debugger

Note 1: The program needs to be debugged at compile time to add the-G option, the program can be debugged

NOTE 2: All of the following commands can be abbreviated initials, example: info break ==> i b except special declaration
    
#gdb Program//Enter debug mode
#list file.c:fanction//Display the Fanction function in the file.c file
#break file.c:fanction//Break a breakpoint at the Fanction function in the file.c file
#break file.c:100//hit a breakpoint on line 100th in the file.c file
#info Break//View all Breakpoints
#delete Break num//To remove breakpoints with a breakpoint number of num
#run//Start running the program
#bt//display stack of programs
#watch expr//monitor the expr variable (the value of the variable is printed each time it runs to the variable) (watch cannot be shortened)
#print expr//Print the value of the expr variable (the variable in the current run function)
#c//Continue to run the program
#next//Single Step operation
#quit//Exit Debugging
