问题
I am using R on AWS EC2 instance. I am trying to send a mail using the "mailR" package.
I was told that to install the package I should previously install the package "rJava" as "mailR" depends on it.
When trying to install "rJava" I get this error:
gcc: error: libgomp.spec: No such file or directory
After a quick search, I saw a post on this link explaining this:
"You have to make sure your GCC has OpenMP support enabled. Make sure you select OpenMP from the optional packages when installing."
I really have no idea how to do this. Should it be something to add in the parameters of install.packages("rJava")?
Assistance much appreciated !

Found the solution here
I did install gcc but apparently we should not install the latest version, so as suggested in the linked post, I downloaded version 4 and it worked.
You do that by typing in Putty:
sudo yum install gcc-4.8.5
Thanks !
