Can't compile on Linux Ubuntu 18.04

[omfmartin]

I tried to install the package on Ubuntu 18.04 and got the following error at compilation. Any idea how I could get it to compile?

Thank you!

The error seems to be coming from cpp11 -- maybe try to update that package and see if it is resolved

[omfmartin]

I was using g++ 7.5.0. I updated it to 11.1.0 and I'm unfortunately still getting the same error.

[thomasp85]

Ah - I'm talking about the cpp11 R package

[omfmartin]

Sorry for the misunderstanding. The R package seems up to date, I'm using cpp11 0.4.2

[thomasp85]

So, it appears that Freetype has a Macro that interferes with R's TYPEOF macro (which is used in cpp11)

However the macro got renamed in 2015 so my guess is you are sitting on a very old freetype version

[omfmartin]

I unfortunately don't have access anymore to the computer where I was having the bug, so I won't be able to confirm. Feel free to close the issue. Thanks for looking into it :)
