Conflict with unistd.h on Mac OS #1046
Description
CC @kevinushey who has also been helping me with this
Minimum package to reproduce issue:
https://github.com/DavisVaughan/testunistd
If I am on the dev version of Rcpp, 1.0.4, then I cannot compile the package linked above. It includes this header declaration ordering:
// Works on 1.0.3
// Fails on github 1.0.4
#include <Rcpp.h>
#include <unistd.h>- If I use 1.0.3, it works as is
- If I reverse the include ordering while on 1.0.4, it works
I am on Mac OS 10.14.5
This is the error that I get, it looks like some conflict with the sys/_types/_uuid_t.h file in the mac SDK, but I haven't been able to track it down any further than this.
