Trying to use the lidR package on RStudio Server and I have been unable to install the dependency 'rlas'. I added some variable to define the Makevars shown here:

CXX14 = g++ -std=c++1y

But still get errors. My console actually fills up beyond the character limit so I can't see where the error begins but there is a lot of repeating text of:

  required from here
/home/mblasdel/R/x86_64-pc-linux-gnu-library/4.0/BH/include/boost/geometry/core/tag.hpp:68:17: 
error: no type named ‘type’ in ‘struct 
boost::geometry::util::remove_cptrref<boost::geometry::model::multi_polygon<boost::geometry::model::
polygon<boost::geometry::model::point<double, 2ul, boost::geometry::cs::cartesian> > > >’

Not sure how to parse all of these errors but I assume there is some C++ issue going on.

System info:

I have this package installed on my Ubuntu laptop so I'm not sure what the issue is with the operating system. I believe the RStudio Server is redhat distribution. Any help would be greatly appreciated.

lidR uses boost geometry which requires in its latest version to compile in C++14. gcc 4.8 is pretty old and does not support full C++14 standard. Only pre-standard C++14 with c++1y. See Compile c++14-code with g++

The CRAN no longer compiles with gcc 4.8. They used 4.9 for old versions of R and gcc > 8 on all other flavours. See https://cran.r-project.org/web/checks/check_flavors.html

So the way is to get a fairly recent compiler I guess. gcc >= 5 should be ok
