Actually, I ran into an error while compiling:
/home/centos/PREPRO/SMOKE/subsys/smoke/src/smkinven/rdemspd.f:304:15:
304 | LFIP = ''
| 1
Error: Cannot convert CHARACTER(0) to INTEGER(4) at (1)
make: *** [Makefile:349: rdemspd.o] Error 1
/home/centos/PREPRO/SMOKE/subsys/smoke/src/smkinven/rdorlfr.f:493:15:
493 | LFIP = ''
| 1
Error: Cannot convert CHARACTER(0) to INTEGER(4) at (1)
make: *** [Makefile:349: rdorlfr.o] Error 1
LFIP is defined as an integer so the error makes sense. I was able to compile by simply substituting with LFIP=0
but I have no clue if this is the intended use.
