[Rcpp-devel] Unable to build Package under Rcpp with Windows XP using canonical Example

Sorry for not being clear. I'd already used verbose=T with inline to check the compile and build steps. The scripts are identical, but inline works and R CMD does not. I've used simpler and simpler examples and re-focused on Rcpp away from RcppArmadillo in an attempt to isolate the problem.
So what I did next was to build a package skeleton under Rcpp with that included the canonical C++ code and R script (Rcpp_hello_world) included there. I built it, but when I checked it; the compile step completed, but the build broke, with the following message:
* installing *source* package 'fooRcpp' ...

I also attempted to build a package under RcppArmadillo using the fastLm C++ code. This is the same code from which I attempted to create a SHLIB. Not surprisingly, I receive the same compile error as before when checking the package:

I'm unable to discover a pattern between these (and other) compile and build errors I'm achieving that would help me solve it. As mentioned, the scripts compile and build fine with inline under the same flag texts. The snprintf issue that appears when I employ RcppArmadillo is not fixable by including cstdio, cstring or locale. Anyway, it doesn't make sense that an idiosyncratic tweak under one scenario will fix the other errors I receive. Again, my Rtools installation is fine with nothing obvious there. I'd appreciate your helping me think through what factors would cause inline to work and R CMD to not when the includes, namespace, wrappers and flag text are *identical* between the two. Anyway, I'm at whit's end since I'm unable to build a package through Rcpp.
Thanks, Terrance.

Good. Now learn about
a) the verbose=TRUE argument to cxxfunction()
b) the RcppArmadillo.package.skeleton() function
| What I'm not able to do is the same through R CMD SHLIB. With Romain's help, the Rcpp/RcppArmadillo dependencies are resolved, but not the simple snprintf error. I don't think there's an issue with my installation of the Rtools toolchain as I've reviewed it a number of times (including environment variable settings). Including additional headers or namespace declarations is not solving this problem. I'm wondering if there is not a Windows issue driving it and whether the root cause is something other than making additional includes on my end.
snprintf is really, really standard.
Dirk

At this point, however, I want to see every method I've tried work, however, so that I understand any and all differences I might expect for developing with Rcpp/RcppArmadillo under Windows XP. So I followed the process (using Verbose=TRUE under an inline invocation) with the bla.cpp you included for me to obtain PKG_LIBS and CLINK-CPPFLAGS values. When I return to my cygwin bash shell session and attempt to compile and link bla.cpp, it does now seem to properly source my #include<RcppArmadillo.h>. statement. I do, however, receive the following error: 'snprintf' is not a member of 'std'. So I guess I'm missing a header linked to std::snprintf. The only thing that comes to mind is that I have somehow corrupted my installation of Rcpp. I would appreciate any insight you would offer.

| | | Hello,
| | |
| | | I would strongly advise you to make it a package, especially if you deal
| | | with multiple files, etc ...
| | |
| | | One thing you might want to consider is to use the verbose argument of
| | | cxxfunction, so that inline shows you how it runs the show.
| | |
| | | For example:
| | |
| | | require(RcppArmadillo)
| | | require(inline)
| | |
| | | f <- cxxfunction( , '
| | | arma::mat x(2,2) ;
| | | NumericMatrix res = wrap( x + x ) ;
| | | return res ;
| | | ', plugin = "RcppArmadillo", verbose = TRUE )
| | |
| | | When you run this, you'll see what inline does with the PKG_LIBS, etc ...:
| | |
| | | For example, it shows me this on OSX:
| | |
| | | romain at naxos ~/svn/rcpp/pkg $ Rscript bla.R

| | |
| | | Then you can just hardcode PKG_LIBS and CLINK_CPPFLAGS (or use

| | |
| | |
| | |
| | | Another tip with inline is that you can read the code from a file, e.g :
| | |
| | | f <- cxxfunction( ,
| | | paste( readLines("bla.cpp"), collapse = "\n") ,
| | | plugin = "RcppArmadillo", verbose = TRUE )
| | |
| | | This way you can import multiple files, etc ... while keeping the C++
| | | code out of the R code. I would still however very strongly recommend
| | | you to make a package. It is well documented, easy and it will save you
| | | some time.
