Hello, how should be an include path for a plugin created by Rcpp:::Rcpp.plugin.maker specified?
I'm using a library which is not in the standard path. I'm able to specify -Wl,-rpath and -L options but I don't know where -I should be specified. As an example I used the GSL example from Rcpp-FAQ. GSL headers are in standard path so everything works. But if I modify this example to use gsl_rng.h instead of gsl/gsl_rng.h it is necessary to set -I/usr/include/gsl somewhere. Only thing which worked for me is: Sys.setenv(PKG_CXXFLAGS="-I/usr/include/gsl/") export CXXFLAGS or PKG_CXXFLAGS in command line (and than running Rscript) or using Makefile="-I/usr/include/gsl/" (plugin.maker param) didn't helped. I also tried myplugin$env$PKG_CXXFLAGS <- "-I/usr/include/gsl/" but I got some R errors. My platform is GNU/Linux, dist. Ubuntu 10.04. Now I'm trying compile simple function only but in the future I want to build some R package too, so I'm asking if there can be problem with this also in this case (I didn't studied documentation for building packages yet). I think that some parameter is missing in the interface (Rcpp.plugin.maker) or that the documentation is not complete (or I'm just missing something of course). Thanks for help, Vaclav _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
