[xcrysden] Running XCrySDen

[Gavin Abo]

The issue might be because the version of Fedora that you are using does 
not have the operating system library that it needs to load ftnunit.  
Thus, the "error while loading" error.


What is the Fedora version?  The xcrysden-1.5.60-bin-semishared worked 
with around Fedora versions 25 to 27.


With Fedora 34, xcrysden 1.6.2 was used, but it had to be compiled.


The compile steps used were given the post at:


http://www.democritos.it/pipermail/xcrysden/2021-April/002050.html


At https://fedoraproject.org , I see that Fedora is now at version 40.  
I've not tried XCrySDen 1.6.2 with that version if that is what you are 
using.


With some other code packages, I have seen some GNU compiler 
compatibility issues encountered with newer Linux distributions that 
release with gcc/g++ version 13.  With Ubuntu 24.04 LTS that comes 
with gcc/g++ version 13, though, I was able to fall back as a workaround 
(while waiting to see if the code developers would provide new versions 
with code changes for working with the newer compilers) for example by 
installing a g++ version 10 package using "sudo apt install g++-10".  
Don't know yet if there are any issues compiling XCrySDen 1.6.2 with the 
latest gcc versions or if Fedora has a similar fall back package that 
can be installed like Ubuntu.


Kind Regards,

Gavin
