problem installing gnuplot

[Ozan K. <oza...@gm...>]

Hi,

I am trying to install gnuplot following the instructions in the INSTALL
file.

I could run  "./prepare" and "./configure" without problems but "make"
failed with the error  message below.

I tried to debug the code, but it exceeded my capacity to do a quick fix. I
also checked online, but I could not find a solution.

Can anyone help?

I am using an M1 Mac, in case it is relevant.

Best,
Ozan
