[Rcpp-devel] Compiling RcppArmadillo through R CMD SHLIB on Windows XP

[Savitsky, Terrance]

Hello, 

 

I employ a variant of the following lines in a cygwin bash session in
Windows XP to compile my .cpp file.

 

$ export PKG_LIBS=`Rscript.exe -e "RcppArmadillo:::LdFlags()"`

$ export PKG_CXXFLAGS=`Rscript.exe -e "RcppArmadillo:::CxxFlags()"`

$ R CMD SHLIB fastLm.cpp

 

I receive the following compile error:

 

G++ -I"C:/PROGRA~1/R/R-212~1.0/include" Rscript.exe -e
"RcppArmadillo:::CxxxFlags()" -O2 - Wall -pedantic - c fastLm.cpp - o
fastLm.o 

 

G++:Rscript.exe: No such file or directory

fastLm.cpp:1:27: error: RcppArmadillo.h: No such file or directory

fastLm.cpp:2: error: 'SEXP' does not have name a type

 

I've included the R bin directory containing Rscript.exe to the PATH
environment statement.   Should one use a different syntax for windows
to capture RcppArmadillo dependencies?  (Fyi, I am able to build using
inline, though my code is 600 lines and I will have multiple versions,
so using the old approach may provide the most modular de-bugging
approach vs. re-installing a package as I add files).

 

Thanks, Terrance Savitsky
