Re: Rcpp alongside NONMEM
Hi Mike,
Similar to Itziar, I've run into near-equivalent problems. I've not tested this as a solution, but my thought is to setup a specific batch file that runs NONMEM for me, and at the top of the batch file it updates the PATH variable to point to the NONMEM copy of gfortran, and at the end, it returns the PATH to its original state.
Currently, I don't have similar problems with my Docker setup since NONMEM and gfortran are within the Docker container and can't reasonably interact with the outside environment.
Thanks,
Bill
