[Gretl-users] Cannot Find Font Arial

[Paul Jones]

Okay, I was able to replicate the environmental variables and the 
command line output you showed me.

However, it had no effect on the error message from Gretl.

Actually, one thing I tried was setting the environmental variables, 
deleting all config files from gretl and gnuplot. That gave me this 
error message the first time I started gretl and made a time series plot.

/home/paul/.gretl/gpttmp.c5KDmt: No such file or directory

When I tried again after restarting gretl, it was back to the old error 
message of not being able to find the Vera font.

That I guess could be a different error completely.

So I don't know what's going on, I do have all these fonts on my system. 
It has always worked. I have read about this problem with GD which does 
seem to be a problem here. This error isn't filed in either gnuplot and 
gretl.

Thanks for you assisstance.
