The build process continued and stopped at a different point, now complaining about the
<b>CarpetX/Arith</b> thorn.<br>
<br>
I have attached the new <code>make.log</code> file.<br>
<br>
I ran the log through ChatGPT, and it suggested that this could be caused by C++ standard mismatches.<br>
Does this sound reasonable to you?<br>
<br>
Currently, the flags for the C and C++ compilers in my config file are like this:</div>

I checked Bruno's file, and the respective options there are the following:</div>

However, I should note that in Bruno's version, all CarpetX-related thorns are disabled in the ini file. </div>

Returning to the compiler options, I suspect that <code>CFLAGS</code> can be left alone.<br>
Do you have any suggestions on how to change <code>CXXFLAGS</code> to bypass the <b>

Oh, I had not noticed, sorry. Hmm, that is the typical cause for these<br>
issues. <br>
<br>
The only other difference I see is `-ffixed-line-length-none` though<br>
that would also point to an issue with the Cactus Fortran file<br>
processing not breaking things into short enough lines. <br>
