Trying to install Rfast in RStudio 4.2.1, C++17 error

[cristiandk]

Hi all
I am very new here so I hope you will bear with me.

I am trying to install the Rfast package in RStudio server 4.2.1 on Amazon Linux 2 CentOS 7, but I get the error
Error: C++17 standard requested but CXX17 is not defined

I can see my version of gcc is 7.3.1, which i believe was installed together with RStudio as a dependency.

Anyone know how i can resolve this?
Should I install gcc10 before I install R and RStudio server?

Thank you all in advance
Best regards

The error message you're seeing is indicating that your version of GCC (7.3.1) does not support C++17, which is a requirement for the Rfast package. You will need to update your GCC version to a version that supports C++17. One way to do this is to use the package manager on your system (e.g. yum or apt) to update GCC. For example, on Amazon Linux 2 you can use the following command:

sudo yum install -y gcc-c++

Another way is to install a more recent version of GCC from source using the following command:

wget https://ftp.gnu.org/gnu/gcc/gcc-10.2.0/gcc-10.2.0.tar.gz
tar -xvf gcc-10.2.0.tar.gz
cd gcc-10.2.0
./contrib/download_prerequisites
./configure --enable-languages=c,c++
make
sudo make install

After updating GCC, you should be able to install Rfast package without any issue.
