[targos]

macOS 10.15 is no longer supported to build node. We require at least macOS 11.

[tobbi]

To me it seems like the build error might not be specific to OS X 10.15.

[targos]

It's specific to the clang version that ships with Xcode on 10.15

[tobbi]

Assuming I fixed that locally and put it under a platform-specific #ifdef guard, would you accept patches?

[ireddick]

I am experiencing something similar on Mac OS 11.7.10

[tobbi]

Does this need to be reported upstream to the maintainers of v8 or to what extent is the version bundled with nodejs up-to-date with that?

[targos]

Official macOS releases are built with Xcode 13.2.1 too and we don't get this error 🤔

I'm getting a similar error when using brew to upgrade node:

I've now successfully built v22.3.0 directly (ie. not via Homebrew) using the same release archive that Homebrew uses in its formula:

https://nodejs.org/dist/v22.3.0/node-v22.3.0.tar.xz

Homebrew formula

I used the default build steps from BUILDING.md

./configure
make -j4

This resulted in a working node executable 👍

I then tried installing v22.3.0 via Homebrew and got the same build error as before, so I'm fairly confident that this is a Homebrew related thing.

Something I've noticed is that Homebrew sets a lot of environment variables and passes a lot of configuration options. This is from the log of my last attempt:

Platform and tools:

Clang: 13.0.0 build 1300
macOS: 11.7.10-x86_64
CLT: 13.2.0.0.1.1638488800
Xcode: 13.2.1

Worth highlighting again that I'm aware that Homebrew no longer supports this OS version.

[markellos918]

Same issue here. I have got the same platform and tools as the previous comment. Similarly, I can build from the release available from nodejs website as well as the node@20 release with Homebrew. I tried editing the node.rb formula to remove most config options, to no avail.

[crystall1nedev]

Same issue here, however for me it's with MacPorts instead of Homebrew. Attempted a build of v22.12.0 earlier today, got the same error:

:info:build ../deps/v8/src/wasm/wasm-engine.cc:157:19: error: no viable overloaded '='
:info:build       source_url_ = String::cast(script->name())->ToCString();

Clang: 13.1.6 build 1316.0.21.2.5
macOS: 11.2.3-arm64
CLT: 13.4.0.0.1.1651278267
Xcode: 13.4.1

Note: There are a few odd things about my setup that might confuse but aren't related to the issue:

• Xcode 13.0-13.2.1 require macOS 11.3, but I have macOS 11.2.3.
• Xcode 13.3-13.4.1 require macOS 12.0, but I have macOS 11.2.3.
• After some patching to version detection, all versions of Xcode 13 work fine on 11.2.3.

Looking at the Portfile, this might be related:

# The Node.js docs says it requires "Xcode >= 13 (Apple LLVM >= 12)" [1]
# and accordingly the compile fails on macOS 11.7 Big Sur with Xcode's
# clang. However, bumping the requirement for clang 1400 or greater
# gets it to successfully compile.
