[R-pkg-devel] R_MAKEVARS_USER fail to pass down to sub-makes?
I think the issue is likely that you seem to be using a relative path to the R_MAKEVARS_USER file, it needs to be an absolute path as the installation is run in a temporary directory not from the directory you call `R CMD INSTALL` from. I observed similar behavior to what you describe when I had the MAKEVARS_USER file as a relative path, but using an absolute path produced the expected result.

Hi package devel support, I am trying to use R_MAKEVARS_USER to customize build, rather than .R/Makevars. It is properly displayed from config CFLAGS but during package install it doesn't seem to work. In R-admin in "6.3.3 Customizing package compilation" there is:
Note that these mechanisms do not work with packages which fail to pass
settings down to sub-makes, perhaps reading etc/Makeconf in makefiles in
subdirectories.
It seems that it applies to me. How should I debug that? to make this
env var respected? Note that my pkg has src/Makevars to handle openmp
switch nicely
Thank you
