Build fails with clang on macOS < 13: Undefined symbols for architecture x86_64: "std::__1::to_chars(char*, char*, double)"

[barracuda156]

Parabolic is in MacPorts now, and turns out linking stage fails for macOS < 13.

Any idea what goes wrong?

P. S. On 10.6 I use gcc with libstdc++, there no errors. Also on macOS 13+ with Apple clang it works fine.

[nlogozzo]

It seems like it's not supporting std::format and std::vformat from C++20. That's required for Parabolic.

[barracuda156]

I see. I did set the requirement for C++20 https://github.com/macports/macports-ports/blob/bacd5a9fb13699ba325c954f929e898a2a4098e2/net/parabolic/Portfile#L42 which in theory is supposed to ensure the correct compiler gets picked, but possibly it did not work quite right here (does clang-17 support the standard in full or partly?). Or otherwise libc++ on those systems does not have these, and then I am not sure if anything can be done easily.

P. S. On a side note, are you interested to be a maintainer for libnick and parabolic? If yes, I will add you.

[nlogozzo]

According to this: https://stackoverflow.com/a/71778011 it should work with libc++17

As far as being a maintainer, sure I guess, but I don't own/use any macOS system.

I plan on trying to create a macOS VM on my Linux machine tho.

[nlogozzo]

Any update on this?

[barracuda156]

Any update on this?

It appears that it needs Xcode 15.3+: https://developer.apple.com/xcode/cpp

The standard may support it, but Apple libc++ may not. While we can pick an arbitrary clang version (or even gcc), that won’t help if libc++ does not have it.
(On PowerPC gcc uses its own libstdc++, so it can support newer stuff regardless of what Apple had.)

There is some chance it would work via legacysupport-supplied libcxx 14 (your link mentions that is was incomplete but might work). I can try adding that today (no harm, in the worst case nothing changes).

This is not your bug, so no need to delay any updates. There is no requirement to support any older macOS versions, it is done as long as it is possible and maintainer is willing to. We may be willing, but it may not be possible here :)

Could I have your e-mail handle, to use for the portfile’s maintainer field?

[barracuda156]

BTW let me close the issue, since it is Apple’s bug, not Parabolic’s.
