https://bugs.freedesktop.org/show_bug.cgi?id=108082 --- Comment #7 from Dylan Baker --- We're not going to track down every ICC unsupported argument warning, ICC is very spammy about unsupported arguments, and getting compiler checks to work with ICC is a huge pain. As long as they're just warnings lets not worry about them. As an aside, I'm trying to get ICC in shape for meson, and there are lots of annoying "helpful" features in that compiler. Hopeuflly it'll be basically working by meson 0.49.0. -- You are receiving this mail because: You are the QA Contact for the bug.

You can't have any logic based on the value of $CC (or $CXX), because `gcc` might be a symlink to `clang` (as is the case by default on MacOS for instance, but I've seen it on Linux as well), and users also use it to add compiler flags. As for the issue, do you guys see the same warning for any other -Wno-foo from our list? I'm 90% sure this is NOTOURBUG as we're already doing all the checks needed, but I want to figure out if it's clang or autotools going bad. Vinson, can you also try meson on your system? It would help narrow down the issue. (I've also checked that there's no typo in the configure.ac check, just in case, and there isn't) -- You are receiving this mail because: You are the assignee for the bug.

meson+autotools: get rid of spammy GCC warning -Wformat-truncation
That warning fires every time a string function takes an argument that
could possibly be longer than its max output, which triggers all over
the place, especially when working with file paths ("what if every file
path is MAX_PATH long?" is what GCC is saying, which is really annoying
when we *know* that "/dev/dri/cardN" is not gonna be 4096 char long and
it's safe to store it in a 32-char array).
Anyway, we either add a ton of dead code all over the place to make GCC
happy, or we get rid of its spam. I chose the latter.
