Cannot install on R3.5

[ms609]

I'm trying to debug one of my packages on a clean install of R3.5.3 but cannot install "fastmap", a dependency of "devtools". (It also fails on R3.5.0 and 3.5.2.) I see:

> install.packages("fastmap")

Is "fastmap" supported on R3.5?

Have you solved this problem yet? I have the same problem o(╥﹏╥)o

You might need to use a newer version of R. Because of changes in R 4.3, packages are no longer allowed to specify SystemRequirements: C++11, which is necessary for this package to compile on R 3.5 and below. In other words, the R/CRAN maintainers required us to make a change which causes this package to not build on 3.5 and below.

See this for more information: https://www.tidyverse.org/blog/2023/03/cran-checks-compiled-code/ Notably:

After making these changes, the package should install without trouble on R 3.6 and above. It may not build on R <= 3.5 on systems with very old compilers, though it is likely that the vast majority of users will have a newer version of R and/or have recent enough compilers.
