[R-pkg-devel] interpreting rhub platform failures

[smallepsilon]

I am preparing my R package for resubmission, and am using the "rhub" package to check it on various platforms. It passes the checks on all but three platforms (intel, nosuggests, and rchk), and I am hoping for guidance on how to interpret the failures.

The package initially failed on the "ubuntu-clang" platform, but it passed when I reran it without any changes. I tried rerunning the checks on intel, nosuggests, and rchk, but it failed again on each one.

The failure details are given below. Should I worry about these errors when I resubmit to CRAN? 

- intel fails because of a problem loading "minqa", which is imported by "lme4", which my package suggests. The message reads:

Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared object '/github/home/R/x86_64-pc-linux-gnu-library/4.6/minqa/libs/minqa.so':
  libquadmath.so.0: cannot open shared object file: No such file or directory

I searched online for related errors, and found nothing about the intel platform from rhub specifically, but https://stackoverflow.com/questions/21149090/error-installing-minqa-in-r-3-0-2 leads me to think that it might be an issue beyond an rhub user's control.

- nosuggests fails because it cannot rebuild the vignettes. The error message is "there is no package called 'rmarkdown'", which is not surprising given that "rmarkdown" is suggested for building vignettes. I hope this is not a deal-breaker for CRAN....

- rchk fails for reasons that I cannot interpret. What I think is the relevant text is given below. My understanding is that this platform is used to test C/Fortran code included in a package, which mine does not use.
