Reporting about the gretl crash: 1) I changed "Use local setting for decimal point" to "on" in my laptop (Ubuntu 20.04 and gretl built on 2022-02-25). StrucTs script worked without problem. 2) Now I changed "Use local setting for decimal point" to "off" in my office's desktop PC (Ubuntu 20.04 and gretl built on 2022-02-23). StructTs script makes gretl crash (the same as with the option in "on". 3) I had a look to gdb (I don't have valgrind installed) but ... now I am not a so advanced linux user. 4) I run the script in a terminal with gretlcli obtaining a halt with this error: "cannot find system Renviron. Fatal error: unable to open the base package". I go to gretl preferences and in "Path to R library" I see "/usr/lib/libR.so" 5) I open a terminal and go to /usr/lib to see if the file exists, yes it exists. The output of ls -ll libR* is lrwxrwxrwx 1 root root 13 nov  2 22:13 libR.so -> R/lib/libR.so I check with a "cat" if the link is working at it is. The original "real" place of libR.so is /usr/lib/R/lib/libR.so 6) I go to gretl's preferences again and change the R library path to /usr/lib/R/lib/libR.so, I try to run the script again and... it works! My conclusion: what is causing the crash is the soft link. Don't ask me why I had a path to this soft link. No idea. -- Ignacio Díaz-Emparanza Departamento de Métodos Cuantitativos Universidad del País Vasco - Euskalherriko Unibertsitatea, UPV/EHU Tfno: (+34) 94 601 3732
