issue with the functions compile_implicit and compile_sys #5

There is a problem with the gcc-c++ compiler. Because it is trying to cast a variable to a string and failing because it's already a string. I've tried upgrading from 4.4.6-4 to the latest version of gcc-c++ for CentOS 6 (4.4.7-18), but the error still occurs.

The functions are working correctly in CentOS 7 with gcc-c++-4.8.3-9.el7.x86_64

I was trying to run the below code (examples in the reference manual) but they are not working and giving a huge error.

compile_sys("logistic", "dxdt = x * (1 - x)") Error in Rcpp::sourceCpp(code = code, env = env, ...) : Error 1 occurred building shared library. compile_implicit("lorenz", Lorenz.sys, pars, TRUE) Error in Rcpp::sourceCpp(code = code, env = env, ...) : Error 1 occurred building shared library.

I'm giving the final two lines of the error.

I'm using odeintr 1.3 and my session info is given below.
