I am trying to install the brotli package in R. As usual, I run: install.packages("brotli")
However, for some reason, the compilation seems to not be completing. I have tried this now on two different systems (one on my Mac, the other on an EC2 instance). Here are the errors:
wrapper.c:94:14: error: unknown type name 'R_CallMethodDef'

I'm not as proficient in C as I probably should be, but I tried to reverse engineer it with no avail. Am I missing something? I also tried to install this with the dependencies option (dependencies = TRUE). Does anyone have any thoughts on this?
So, it seems as thought, through some additional poking in the C code, that the solution was really simple. I just didn't have r-development installed. After installing on both my mac and my EC2, it now installs with no issue. This is strange, since I would imagine that a decent R package should be able to be installed without the need of the development packages. But maybe I'm too inexperienced in R package development to comment an opinion on the matter. None-the-less, I hope this helps other less-experienced that are seeking to install the same package. Thanks for the help though!
