This blog is updated daily.
A general description is here.
‘R CMD check’ now reports the compilers (and on macOS, the SDK) used
for packages with compiled code. (In progress.)
Where recorded, it reports the C and Fortran compilers used to build R.
Where recorded at installation, ‘R CMD check’ reports the C and Fortran compilers used to build R.
‘R CMD INSTALL’ reports the compilers (and on macOS, the SDK) used, and this is copied to the output of ‘R CMD check’
The use of ‘sprintf’ and ‘vsprintf’ from C/C++ has been deprecated in macOS 13 and is a known security risk. ‘R CMD check’ now reports (on all platforms) if their use is found in compiled code: replace by ‘snprintf’ or ‘vsnprintf’ respectively. [*NB:* whether such calls get compiled into the package is platform-dependent.]
