Common parameters:-o specify the generated output file-E only performs compilation preprocessing-S converts C code to assembly code-wall displays warning messages-c only performs compilation operations, no connection operations refer to examples and no options to compile files:

[root@linux265 ~] # gcc linux265.c preprocesses, assembles, compiles and links linux265.c to form an executable file linux265:

[root@linux265 ~] # gcc linux265.c-o linux265 outputs linux265.c preprocessing to linux265.i file:

[root@linux265 ~] # gcc-E linux265.c-o linux265.i compiles linux265.c and linux265_1.c separately and links them to linux265_2 executable files:

[root@linux265 ~] # gcc linux265.c linux265_1.c-o linux265_2 outputs linux265.c preprocessing to linux265.i file:

[root@linux265] # gcc-E linux265.c-o linux265.i is all the contents of this article entitled "how to use gcc with Linux commands". Thank you for reading! Hope to share the content to help you, more related knowledge, welcome to follow the industry information channel!
