I am trying out the Goddy cloud server with the following specific:

20GB
No more than
$5.00 /month
($0.0074 /hour)
512MB memory
1 core processor
20GB SSD disk
1TB transfer

However, when I install the shiny package, I got the following error message

g++: internal compiler error: Killed (program cc1plus)

It turned out there was enough memory on the server. I was able to solve the problem by temporarily adding a larger swap file using the method discussed here: http://lacey.se/posts/compiling-dplyr-on-low-memory-vps/

To do it, use the following script

sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

Then, install the package using

CXXFLAGS="-g -O2 --param ggc-min-expand=0  --param ggc-min-heapsize=8192" sudo su - -c "R -e \"install.packages('shiny', repos='http://cran.rstudio.com/')\""
