[建議] 關於 compile 時的 warning message

[ric2k1 (Ric)]

建議大家將 compiler warning message 的 option 打開 !!

(難怪他對於 unused variable 沒有 warning..)


For devC++:

   Tools --> Compiler Options

   在 "Add the following commands when calling compiler" 以及

      "Add these commands to the linker command line"

   加入:

   -Wall

   他將會 turn on 所有 warning message.

   [Note] Make sure when you move to another file or call the devC++ again,

          the options are still there...



For Linux:

   When calling g++, please specify the "-Wall -g" options.

   ==> g++ -Wall -g ....

   Note: -g is to turn on the debugging information.

   Note: You can add

         alias myg++ "g++ -Wall -g" to your .bashrc (your shell script)

         so that you don't need to specify the options everytime.

         You can just do "myg++ ...".



I don't know about Visual C++. 知道的人請補充...

推 jimjjj:visual C++ 的warning 和 error message是自動一起的
推 ric2k1:自動一起? int main() { int a; } 會不會有 warning?
推 jimjjj:和error message混在一起顯示(都在同一個框)..會的
推 ilway25:老師的意思是他不知道 VC++ 怎麼讓warning 顯示「多一點」
推 ric2k1:是的, 我就是樓上說的那個意思...
