[Rcppoctave-user] Cannot load RcppOctave.so onto Mac OS

Hi all again,


I have successfully compile, install and load RcppOctave on my Mac (running Mavericks). In order to do this I have to reinstall Rcpp with customized ~/.R/Makevars (CC=clang, etc). I can load the library from the command line R but not from the GUI. It should be something related to the search path because octave-config could not be found. I will post it here if I find a way. In the meantime, any suggestions would be very welcome. Thanks very much.

Yitping



From the command line:
> library(RcppOctave)
Loading required package: Rcpp
Loading required package: pkgmaker
Loading required package: registry
RcppOctave [0.13.3] - Octave 3.6.4-api-v48+ (x86_64-apple-darwin13.0.0)
Octave path: /opt/local/bin

From the GUI:
> library(RcppOctave)
Loading required package: Rcpp
Loading required package: pkgmaker
Loading required package: registry
RcppOctave [0.13.3] - Octave (not configured)
NOTE: Octave binaries were probably not found. See ?octave_config.
Warning messages:
1: In value[[3L]](cond) :
  Failed loading Octave configuration: Error in base::system(..., intern = TRUE): error in running command

2: In value[[3L]](cond) :

sh: octave-config: command not found
