[Rcpp-devel] Using Rcpp with <nloptrApi.h> results in "shared object 'nloptC.so' not found"

[Simon Zehnder]

Hi Dirk,

thanks for the quick reply. Running the RcppNLoptExample ran also on my
side, however running my code from the repo resulted in an error. I was so
used to having a complicated setup when using nlopt in my C++ code from
before that In over-complicated things.

Thanks for pushing me towards the solution.

Best
Simon
