compilation aborted for parse.cpp

Trying to build ~ on our campus cluster.

cat /etc/centos-release CentOS Linux release 7.4.1708 (Core)

icpc -v icpc version 19.0.1.144 (gcc version 8.5.0 compatibility)

cat ~/.R/Makevars MAKEFLAGS = -j20

the following attempt to avoid missing CXX17 definition in R config

CXX17 = icpc CXX17STD = -std=c++17 CXX17FLAGS = -fPIC -qopenmp -O3 -ipo -xHost -multiple-processes -flto CXX17PICFLAGS = -fpic

Please let me know if I can supply more information. Thanks. Best, CB

While I am unsure about the specifics of icpc compiler, I suspect you case is a standard case of CentOS 7 being too old. We usually recommend either devtoolset from RH, or picking an older release of RcppTOML that does not require C++17.

You can search the previous (closed) issues. RcppTOML is otherwise fine on current toolchains. From CRAN:

So that ball is in your corner I am afraid.

Closing for lack of follow-up. If you think something needs to be added, please open a new issue, ideally with reproducible examples.
