Re: [Pdl-general] pgplot instructions for Big Sur macOS

[Karl G. <kar...@ma...>]

Hi all

An update on this. The config there uses Apple’s CC, but I have now come across some random segv’s that seem to be avoided if one uses GCC 11 and GFORTRAN 11.

So I would recommend editing gfortran_cc_BigSur.conf from that patch to use GCC - and take it from http://hpc.sourceforge.net <http://hpc.sourceforge.net/> (which is where I got GFORTRAN)

The patch selects drivers that work and are relevant today, fixes up the makefile generator, and changes one line of code in the png driver to avoid an error.
