ORTEP Fails to compile

[FOSSBOSS]

I am trying to install ortep III on a CentOS Linux server which has an i7 processor, and where x11, and pgplot are both installed. the make command returns:

gfortran -lpgplot -o ortep3 ortep.o

Which version of CentOS are you using? You may need to install pgplot-devel

[N0rbert]

On all modern linux distros the pgplot is 5.2.2, it is not compatible with this great software from 2000s.

On Ubuntu it may be compiled by following this Q&A - https://askubuntu.com/a/1222216/66509 .
The main difference here - is to download patched version of ortep.f with disabled pgplot functionality from http://ftp.corbina.net/pub/Linux/gentoo/distfiles/81/ortep.f .
