Thank you for your help, Dima.
For the first thing you are right:
Jack: ~ % ls -l /usr/local/include/gmp.h
lrwxr-xr-x 1 Jack admin 33 2 Dec 19:47 /usr/local/include/gmp.h@ ->
../Cellar/gmp/6.3.0/include/gmp.h
Jack: ~ % ls -l /usr/local/Cellar/gmp/6.3.0/include/gmp.h
-rw-r--r-- 1 Jack admin 84307 29 Jul 2023
/usr/local/Cellar/gmp/6.3.0/include/gmp.h
Secondly, you are also right
Jack: test % clang++ -c x.cpp
x.cpp:1:10: fatal error: 'iosfwd' file not found
1 | #include <iosfwd>
| ^~~~~~~~
1 error generated.
Now I'm just not sure how to fix this, but I guess this is going a little
too far away from Sage for it to be your problem! I'll see if I can fix this
