How to set the codeblocks when double-click the error message, the cursor automatically jump to the error line?
It does that already, but you need to do it in the "Build messages" pane, not the "Build log"
Sorry, i first time using the IDE , i not understand you..can you say it more detailedly.

Do you see the red icon and the text "Build messages"?
Click it to show the build messages pane, there you can click on errors.
Be aware, that jumping to an error or warning might not work if you have special (not ascii/english) characters (like e.g. german umlauts or probably cyrillic, chinese or whatsoever characters) in the path- or filename.
Oh , i see.thank you.
