RStudio Server Pro with devtoolset enabled

Follow

When using RStudio Server Pro on CentOS/RHEL 6, a common issue is the GCC version available is not sufficient for C++ 2011 code.  This will return errors similar to the following for example, when installing the odbc package:

 

cc1plus: error: unrecognized command line option "-std=c++11"

 

To work around this issue, you can install and enable the devtoolset. 

For example, on CentOS 6:

(While these instructions were developed for CentOS 6, they will work for CentOS 7, as well, if you are seeing the same error or would like to use a newer version of GCC.) 

 

  1. yum install centos-release-scl
  2. yum install devtoolset-7
  3. Execute: gcc -v
  4. Enable devtoolset-7 with:  source /opt/rh/devtoolset-7/enable
  5. Review gcc version now with:  gcc -v

 

Once tested, you can implement this on RStudio Server Pro by using the rsession-profile

For example:

 

1.  Create the /etc/rstudio/rsession-profile.

vi /etc/rstudio/rsession-profile

2.  rsession-profile contents:

cat /etc/rstudio/rsession-profile

source /opt/rh/devtoolset-7/enable

 

3. Allow access to the file with:  chmod 755 /etc/rstudio/rsession-profile​


4.  This will apply to all new sessions now.  You may wish to restart the service to force any existing sessions to reload.

 

To verify the change from the IDE on a new session, execute:

system("gcc -v")

Example output:
