[Gretl-users] Re: C/C++ api function "corrgram()" does show ACF and PACF chart

Thank you very much, I kind of thought the problem was something like that. The new code now generates two errors. They are 1. Line-> gretl_set_path_by_name("gnuplot", "/usr/bin/gnuplot"); generates error: ‘gretl_set_path_by_name’ was not declared in this scope 2. Line -> opt |= OPT_U; /* add --plot=<whatever> */ generates error: invalid conversion from ‘int’ to ‘gretlopt’ [-fpermissive] For 1. I tried grep --include=\*.{c,h} -rnw '/home/ryan/gretl-2020b' -e "gretl_set_path_by_name" to see if I could find which header file had the function but it returns nothing. Also for-> opt |= OPT_U; /* add --plot=<whatever> */ what does OPT_U and all the other OPT_.... mean/stand for. Like is OPT_U=corrgram plot, and OPT_R= Time series plot, or am I just missing how that entire line of code works? Thank you Riley
