I also got that missing libintl.h file issue on Mac Silicon. Instead of messing
up with Homebrew and its non-standard directories, I installed gettext from
Simon Urbanek recipies. This is really simple and libintl.h is then
automatically found by the compiler without requiring special compilation
flags. You need to start R in sudo mode.
sudo R
Then in R:
source("https://mac.R-project.org/bin/install.R";)
install.libs("gettext")
And that’s it. No more libintl.h problem.
Best,
Philippe
