[Gretl-users] Re: std::string will cause 1.Gretl to delete all files in a folder and cause 2.correlogram_plot to not show plot C/C++ API

That is very interesting since it is a gretl file that is causing the problem. The code I sent does not declare any variable named-> z.I think my version of Gretl might be earlier than yours. I am using gretl: gui client for gretl version 2020b and compiling with gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1). Do you think that maybe the different versions is the reason you are getting this error and not me? Riley
