The best method I've found is to match the line numbers on the lefthand side with the line number the warning mentions. You can also look up the error code by copy-pasting it into google. (I often use C++, but hopefully this i still good advice)

you will read at the ERROR and you look for collum and line than you go to your code and look this Line, after that you read what is happening if is an function not founded and you seach it at google. it depends of the error.

i think first u have to see the line number on the left , then check if you syntax is true, and basically compiler error are simple when u refer to line.

To deal with the warnings or errors thrown during build/compilation, Its best to understand the warnings/errors as sometimes the cause of warnings is the problem in some other files/dependencies/path/violation/exception but the warnings/errors shown at other lines. And the best way to understand some warnings /errors comes from practice and when you encounters the same. So, its the part of the experience!. Again highlighting, the nature of warnings/errors have not mandatory to have the concrete solution as the build process is not a singular process! and also the dependency changes as platform changes!
