Messages in this thread Patch in this message | | | From | Youngmin Nam <> | Subject | [PATCH] Makefile.extrawarn: add -Wformat-insufficient-args for clang build | Date | Sat, 16 Jul 2022 17:45:32 +0900 |
| |
The -Wformat-insufficient-args for clang is useful to detect the situation when the total number is unmatched between format specifiers and arguments.
Originally, this option is enabled by default(Link[1]), but it is disabled by -Wno-format explicitly so that we can't detect this unmatched situation.
We can enable it by adding this option after -Wno-format.
