On a Ubuntu system I built the latest UCBLogo release (6.2.5) without a GUI:
./configure --disable-wx
make
make install
I run a script file that doesn’t contain any turtle commands either directly from the text editor Geany (command “ucblogo ./%f”) or by passing it as a command line argument.
ucblogo file.lg
In this setup UTF-8 characters are displayed correctly.
Plots and thematic maps are rendered with Gnuplot, a command-line plotting utility, driven by two UCBLogo functions.
I use the following startup file.
setprefix "/home/guido/Documenti/ucblogo/programmi
.setsegmentsize 16000 * 150
load "csv.lg
load "df.lg
load "str.lg
load "rs.lg
load "st.lg
