Dear Rcpp experts,
I'm using RcppArmadillo and I'm facing a conflict on the asin, acos, atan and
fabs functions I hardly manage to understand (the conflict appears under linux
but not under windows)
- -------- My header looks like this :
#define ARMA_DONT_USE_CXX11
#include "R.h" // R functions
#include <RcppArmadillo.h>
#include <assert.h>
#include <netcdf>
#include <cstdlib>
#include <cstring>
#include <iostream>
#include <solar_geometry.h>
#include <clsmodel.h>
using namespace Rcpp;
using namespace RcppArmadillo;
//
using namespace netCDF;
using namespace netCDF::exceptions;
---------- the compilation runs like this
g++ -m64 -I/usr/include/R -DNDEBUG -std=c++0x -I../inst/include/ -I/usr/include
/usr/local/include -I"/usr/lib64/R/include" -I/usr/local/include
-I"/usr/lib64/R/library/RcppArmadillo/include"
-I"/usr/lib64/R/library/Rcpp/include" `/usr/lib64/R/bin/Rscript -e
"Rcpp:::CxxFlags()"` `pkg-config --cflags netcdf` /usr/local/include -fopenmp
-lnetcdf -lnetcdf.7 -lnetcdf_c++4 -lsolar_geometry -lclsmodel -fpic -O2 -g
-pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m64 -mtune=generic -c Module.cc -o Module.o
---------- and the error message has
In file included from
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../include/c++/4.4.7/tr1/complex:47,
from /usr/lib64/R/library/RcppArmadillo/include/armadillo:74,
from
/usr/lib64/R/library/RcppArmadillo/include/RcppArmadilloForward.h:46,
from
/usr/lib64/R/library/RcppArmadillo/include/RcppArmadillo.h:30,
from ../inst/include/FluctRES.h:18,
from Module.cc:9:
/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../include/c++/4.4.7/tr1_impl/complex:40:
error: ‘template<class _Tp> std::complex<_Tp> std::tr1::acos(const
std::complex<_Tp>&)’ conflicts with previous using declaration ‘template<class
_Tp> std::complex<_Tp> std::acos(const std::complex<_Tp>&)’
---
I tried to call std::acos ... instead of acos in my code but the error is still
here. Sorry that my example is not really "elementary" and I hope I'm on the
right list..
I guess I'm including twice something by wrong use of using namespace and I saw
that #define ARMA_DONT_USE_CXX11 implies the load of #include <tr1/complex>
(in file armadillo)
Is any help possible from this mailing list ?
Thanks in advance
Best regards
Robin
