Re: [Rd] Makevars CXX_STD variable ignored when no *.cpp files in src/
Radoslaw sent me a reproducible example. I have been able to identify the problem and fix it. I have copied in Alexander Loboda who previously reported the same problem. Briefly, the tools package relied on the presence of files with extension .cpp or .cc in the src directory to determine whether the C++ compiler is required. In the absence of any such files, the code to set the C++ compiler flags correctly was never run.

You are not the first person to report this, but last time when I tried it myself I could not reproduce the bug. Let me try it again.

[Rd] Makevars CXX_STD variable ignored when no *.cpp files in src/
Hello! I might have found a bug in the way that R handles Makevars file when building a package. Value of variable CXX_STD is ignored - i.e. R does not use the correct compiler/flags - if there are no *.cpp files directly in the src/ directory (e.g. all *.cpp are in subdirectories, and OBJECTS variable is set accordingly). Adding a bogus *.cpp file fixes this issue. However, this is not very obvious (I would dare saying it is not obvious at all) and I spent quite a time checking what went wrong after I organized my src files better. :-) Kind regards, Radosław Piliszek __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
