Error: Rank mismatch between actual argument at (1) and actual argument at (2) (scalar and rank-1) in PyOpt

Question

I am attempting to install pyOpt and have run into an error where the Mingw64 gfortran compiler throws an error. It appears that the variable 'g' is held in a common block in an include file while 'dum' is locally declared. What can be done to overcome these errors?

Warning: 'rhoc' may be used uninitialized in this function [-Wmaybe-uninitialized]

Answer 1

you may just need to add the following flag to the compilerfile or makefile that sets everything up.

-fallow-argument-mismatch

where my file looks like this.. and my line was called COMOTT1

startfile

###COMPILE=f77
###COMPILE=pgf90 
COMPILE=gfortran


 COMLIB1=

#COMOTT1=-dalign -O3 -r8
###COMOTT1=-dalign -fast -r8
#COMOTT1=-Ofast -mips4 -IPA -r8
# COMOTT1=  -fast -O3 -r8
 COMOTT1=  -Ofast -fdefault-real-8 -fallow-argument-mismatch
### COMOTT1=  -fast  

# COMCONV= -byteswapio 
 COMCONV= -fconvert=swap

FILES= \
       cpl_bcinterp.o \
       cpl_land.o \
       cpl_main_interface.o \
       cpl_sea.o \
       cpl_sea_model.o \
       dyn_geop.o \
       dyn_grtend.o \
       dyn_implic.o \
       dyn_sptend.o \
       dyn_step.o \
       dyn_stloop.o \

endfile

so hopefully that works for you
