There is something wrong with your R installation. You're passing an -fopenmp flag to the compiler which shouldn't be there. Probably in your ~/R/environment or so.

[thierrygosselin]

the -fopenmp is required if I want to run Random Forest on multiple CPU...

[jeroen]

well according to your own output, you're setting it somewhere where it is not supported...

[thierrygosselin]

Turned off -fopenmp flag in ~/.R/Makevars file and it worked with install.packages("hunspell").

First time I get problem with -fopenmp option during install...

[jeroen]

I guess you usually don't install packages from source? There is really nothing special about the hunspell package.
