Hi all, I'm a relative beginner in c/c++ and I'm trying to use c/c++ libraries in an R package. I need it to work in Windows, though, and I'm struggling to get things working.
Environment: R 3,0,2 Rtools 3.0 cygwin Native CMake 2.8 cygwin 2.8 The cygwin CMake is convinced that the gcc installed by Rtools doesn't work, because it's passing cygwin paths in the generated Unix Makefiles. The gcc fails the testCCompiler.c check with an error "gcc.exe: fatal error: no input files". If I try to actually compile the file manually, it works as long as I use either relative or native windows paths. and The native CMake refuses to use the Rtools gcc with MinGW Makefiles I have some questions: 1) What would I have to do to be able to use the cygwin mingw compiler instead of the Rtools version? The documentation[http://cran.r-project.org/doc/manuals/R-admin.html#The-MinGW_002dw64-toolchain] states: Users developing packages with Rcpp need to ensure that they use a version built with exactly the same toolchain as their package: the recommendation is to build Rcpp from its sources yourself. Do I simply need to install Rcpp from source using my target compiler? Will that effect my ability to use the binary package on other systems(with CRAN Rcpp)? 2) The RInside package contains several cmake examples. The windows examples seem to imply cygwin, but I am unable to run them as indicated. I get the same gcc error: "no input files". Thanks for any help you can offer, --Jamie Jamie Olson _______________________________________________ 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
