The issue is that constexpr requires compiling with C++11 standard or above. R 4.3 and newer use C++17 as the default standard for compiling C++ code, which is why you see clang++ -std=gnu++17 in the first few lines. However, it does not set the default standard for Objective C++ code, which is what mac/FontManagerMac.mm is written in. Without the -std flag, macOS's clang++ uses ancient gnu++98 standard, leading to the compilation error.

I don't know why R does not set the standard for Objective C++ code, and it is not even affected by the CXX_STD variable in Makevars file. Not sure whether it is the intended behavior or a bug of R.

The most straightforward way to build systemfonts is to add the line OBJCXXFLAGS += ${CXX17STD} in your personal Makevars file. The maintainers here may consider setting PKG_OBJCXXFLAGS=${CXX17STD} @objcflags@ in src/Makevars.in.

Thanks for the insight @ywwry66

I do find it strange that there is no issues compiling on CRAN, GitHub Actions or my own machine with the current Makevars if it is a general issue

[ywwry66]

I looked at GitHub Actions, where two macOS environments are tested:

1. macos-13 (oldrel): macOS Ventura (13), Apple Clang 15.0.0, failed with the same error here.
2. macos-latest (release): macOS Sonoma (14), Apple Clang 14.0.0, build suceeded.

My environment is the same as OP's: macOS Sequoia (15), Apple Clang 16.0.0. So this could be an issue with Apple Clang 15.0.0+. @thomasp85 Do you know how to retrieve the compilation logs for the macos-latest (release) test? All I can see is

* installing the package to build vignettes
* creating vignettes ... OK

which indicates a successful build.

I am having the same issue on an M1 Mac Mini, running MacOS 15.2. Fortunately CPAN allows you to install the previous version as a workaround for the moment, but I thought I would mention it to ensure that it wasn't just a problem isolated to a single person's machine.

I have done all my data analysis learning and course work in R and RStudio, my thanks for contributing to such great software 😄 If there is any technical information I can provide, please let me know!

[Tom271]

I was coming across a similar error (also Sequoia 15.1.1). Following @ywwry66 's suggestion above, I successfully installed systemfonts using:

withr::with_makevars(c(OBJCXXFLAGS = "${CXX17STD}"), install.packages('systemfonts'))

[pdbartlett]

Works for me too! Thanks.
