Greetings and thanks for previously offered solutions, I am developing a package that makes use of C++ code, and I want to compile this code for testing reasons with the "R CMD SHLIB" command. Using Ubuntu and gcc 5.4, and because for certain reasons I have to use the c++0x standard, I try the following command:
> MAKEFLAGS='CXXFLAGS=-std=c++0x -lpthread -O2' R CMD SHLIB MyMainCode.cpp For some weird reason, flag -O2 is not recognized properly and I get the following error message: > make: *** unknown output-sync type '2'. Stop. If I try -O3, I get "unknown output-sync type '3' ", and so on. Everything works fine if I drop this optimization flag. Could you suggest a workaround for that? thanks in advance, --Constantinos [[alternative HTML version deleted]] ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
