FreeBSD Build fails: build sets invalid option '-Wno-nan-infinity-disabled' [-Werror,-Wunknown-warning-option]

[yurivict]

Bug Description: See the log.

Surge XT Version

• Version: 1.3.2 1.3.4

Reproduction Steps: Regular build.

Expected Behavior: A clear and concise description of what you expected to happen.

Screenshots: If applicable, add screenshots/GIF/videos to help explain your problem.

Computer Information (please complete the following!):

• OS: FreeBSD 14.1, FreeBSD 15-CURRENT
• clang-18

Additional Information: I think that the unknown warning -Wno-nan-infinity-disabled from some of the dependencies is elevated to the error status by the -Werror option that you set.

Link to #7730

looks like we don’t work with clang 18 yup

[yurivict]

Actually I would like to correct my original post.

The problem occurs with clang-16. clang-18 fixed the problem.

nan-infinity-disabled isn't known to the earlier clang which is elevated to error by -Werror.

[baconpaul]

Hmm

paul ~/dev/music/surge (release-xt/1.3.4) % grep -r "infinity-disabled" cmake libs src CMakeLists.txt scripts 
paul ~/dev/music/surge (release-xt/1.3.4) % 

I can't find where we set that. Is your build process changing flags somewhere? or have you changed the source of some of the libraries?

[baconpaul]

Yeah i looked in your log. At the top is this

--MAKE_ENV--

--End MAKE_ENV--

with the relevant section being

CFLAGS="-O2 -pipe  -Wno-nan-infinity-disabled  ...

so it is definitely the case that if you set -Wno-nan-infinity-disabled and then use a compiler that doesn't support it with a package that compilers with Werror on, it will fail, because you've configured it in an error state I guess.

Where does that segment come from? It's not me though so nothing to be done here I don't think!

[yurivict]

I couldn't find -Wno-nan-infinity-disabled either, but it appears after configure is done. Some dependency adds it, but I couldn't track down which one.

In order to isolate from such issues, it's best to disable -Werror in production builds. Some projects use cmake option for this, like ${PROJECT_NAME}_USE_WERROR.

[yurivict]

NINJA is used to build it by the ports framework. It doesn't add any -Wxx arguments.

[baconpaul]

The -Wno.... is in your log that you shared so it is definitely being added by your build system.

I guess I could add a skip werror flag sure when i'm next in the cmake. but really the solution is to not add arbitrary build flags to the build!

[baconpaul]

Oh or just add Wno-unknown-warning-option to the warnings we bypass I guess (and I suppose you could do the same in your eng to patch now).

seems like there’s two things

1. if clang version is 18 surge needs to add the no man Infinity flag thing which would fix 7730
2. If build type is released add the no unknown warning thing if the compiler is clang any version

and that should do it right?

[yurivict]

Ah, yes .... Sorry, I didn't notice the obvious.

-Wno-nan-infinity-disabled' was added to mitigate this bug: https://github.com/surge-synthesizer/surge/issues/7730

[baconpaul]

Right. So where you added that perhaps also add -Wno-unknown-warning-option and then this one will be fixed until we fix 7730? See what I mean

[yurivict]

Yes, that's what I am doing.
