if you're just using clang, then you should use the pragma syntax for sources you maintain (assuming it is impossible to remove the warning by altering the program appropriately).
here
is the syntax:
if these are programs you cannot change and don't maintain, you should specify the warning(s) to disable for the file, rather than all. to disable all, you can add the per file argument
sources change, and some warnings do (or do not) apply with different build settings. clang's messages can tell you what flag equates to the generated warning.
To use Xcode to alter a file's build flags:
select the target
select the build phase
locate the file to modify the arguments in the "Compile Sources" phase
double click its "Compiler Flags" cell to edit
===== clang 是个什么东东。。。。。。。。。。。
I had no interest in fixing since I will be removing that code from the project in the near future.
You can disable static analyzer warnings for a specific file by including the following compiler flag:
You can combine this with -w to disable warnings for that file as well. That has allowed me to push forward with new development while not having to be pestered with the 30 or so warnings generated by that code base.
Using the instructions from above: To use Xcode to alter a file's build flags:
select the target
select the build phase
locate the file to modify the arguments in the "Compile Sources" phase
double click its "Compiler Flags" cell to edit
add "-w -Xanalyzer -analyzer-disable-checker" to suppress warnings and clang warnings
if you're just using clang, then you should use the pragma syntax for sources you maintain (assuming it is impossible to remove the warning by altering the program appropriately).
here
is the syntax:
#pragma clang diagnostic push #pragma clang diagnostic ignored "-Wmultichar" char b = 'df'; // no warning. #pragma clang diagnostic pop

-w.
