installation warning: skipping pax global extended headers

[tyner]

I am on x86_64-w64-mingw32/x64 (64-bit) running R version 4.1.3. My Rtools is version 4.0. I am able to install (from source) version 5.0.2 of curl with no issues. However, when I try to upgrade to a more recent version, it gives a warning:

• installing source package 'curl' ...
  ** package 'curl' successfully unpacked and MD5 sums checked
  ** using staged installation
  ** libs

*** arch - i386

wondering if this can be safely ignored (i.e. by setting options(warn=1) in my Rprofile), or if it indicates a potential misconfiguration somewhere in the toolchain. Thanks!

Yes this is harmless, it happens because you run such an old version of R. The error will disappear if you update to at least R 4.2, but you can safely ignore it on older versions of R.
