Installation failure on RHEL 7.9

[whipson]

I'm trying to install V8 on an on premises server running RHEL 7.9. I've set DISABLE_STATIC_LIBV8=1. I'm getting the following error - seems to be related to C++ compilation.

Which version of R and gcc and libv8 do you have installed? Did you install libv8 from EPEL? Can you show output of

g++ --version

And

yum info v8-devel

Hmmm it seems that EPEL has upgraded their v8-devel to a version that requires more recent compilers from Redhat Developer Tools...

[jeroen]

Not sure if this is an option for you, but I tested it with the RedHat devtools compilers. This works on CentOS7:

yum install -y centos-release-scl
yum install -y devtoolset-9-gcc-c++

You can set the CXX17 compiler in R by creating a file ~/.R/Makevars that contains the following:

CXX17=/opt/rh/devtoolset-9/root/usr/bin/g++ -std=gnu++17
CXX17FLAGS=$(CXX11FLAGS)
CXX17PICFLAGS=$(CXX11PICFLAGS)

Alternatively you can set these fields globally for all users in the $(R RHOME)/etc/Makeconf file.

This should work, you can now try to install the V8 package in R.

By the way, there are many R packages these days that require more recent compilers than gcc 4.8. You can automatically but the devtools compilers on the PATH like so:

echo "source /opt/rh/devtoolset-9/enable" >> /etc/bashrc

Now if you restart the machine, g++ --version should give you g++9.

Thanks that seems to have resolved the issue

[jeroen]

By the way, is there any reason you want to use DISABLE_STATIC_LIBV8=1 ? Usually the static libv8 is the easiest solution.

[whipson]

I'd previously tried with DISABLE_STATIC_LIBV8=1 because I saw it is a solution in some previous related issues. When I tried your solution here, I returned it to empty.
