How to achieve 0 error (s) and 0 warning (s) in keil5

Use keil This software has been used for more than four years , From the initial keil4 To the present keil535, The compiler has been used since V5.06 To the present v6.16, The compilation speed has been improved a lot , before rebuild Once 3 More minutes , Now it's just a matter of 13s, It really reduces the time of fishing .

keil The installation and cracking of are basic operations , I recommend you to use keil5.3 Version above , So you can use the default v6.16 Compiler .

  So how to make sure there are no mistakes and warnings , First, force yourself not to accept any mistakes and warnings , Otherwise you can't write good code （ At least in the eyes of the compiler ）.

Facing mistakes , We must correct , Otherwise, the program cannot run , In this compiler C++ Function if not void type , Then there must be a return value , Otherwise, an error will be reported . contrast v5 compiler , It's just a warning . For other errors, follow C++ Just modify the grammar rules .

Face warning , Many people choose to ignore , But I can't stand it , To eliminate the warning . Most warnings can be eliminated , Face the warning that cannot be eliminated , Only a unique skill .

  Two warnings are masked in the figure , Source file code and C Under the language, there is the transformation of conforming pointer and unsigned pointer .

If you open the project ,#include “xxx” There is a red fork in front , The problem is described as a multi byte object code page , There is no such thing Unicode Characters that can be mapped to , Description the project path contains Chinese , You need to change the Chinese of the path , Because this compiler does not support Chinese very well .

Many blogs mention turning off dynamic syntax checking , I really don't recommend this , Because there may be something wrong with the software .

Just upgraded to AC6.13 When , I found that there were no mistakes in many places , But there will be a red fork in front , My understanding is that this compiler does not automatically recognize C++ and C The header file , That is to say, they are all .h file , The default in accordance with the C language processing , In this way, the compilation can pass , But it looks awful , After tossing for a long time , Upgrade compiler selected , After upgrading the compiler separately , Cracking the compiler directly will cause keil An embarrassing situation that has not been solved ... Finally upgraded keil edition , Solved the problem .

When you see this , Feel good inside .（ PC is 12 It's old in , Compiled with 33s）

  In conclusion ：1, upgrade keil edition , It is recommended to use ac6.16 compiler ;2, Correct all errors ;3, Modify warnings that can be modified , Shield those that cannot be modified .4, There are other questions , Check the data .
