problem to use AUTO-07p with macOS Catalina

[Amaa486]

My MacBook is macOS Catalina, Version 10.15.5.
I have installed AUTO-07p, followed the steps as in the manual. BUT there is a problem as explained below. For example when I work on "ab", which is in demos, I typed:
>> load(e='ab')

this is no problem for this , but when I typed

>> rn(c='ab')

I have received the following message:

gfortran -fopenmp -O -c ab.f90 -o ab.o
gfortran -fopenmp -O ab.o -o ab.exe /Users/aldurayhim/Downloads/auto/07p/lib/*.o

Any help please thanks in advance

Can you do:
ls -l /Users/aldurayhim/Downloads/auto/07p/lib/*.o
dgemv is normally found in blas.o, it could be that that file's compilation is not up to date.

[Amaa486]

Thanks bartoldeman for your reply. I cannot find blas.o in the list, after entering that command I have received:

As I cann't find the blas.o, I thought I should install blas library so I type:

brew install openblas
but the problem still there.

[bartoldeman]

there are actually more files missing (e.g. main.o), so it looks like you had a compilation error. Please do:

cd /Users/aldurayhim/Downloads/auto/07p/src
make

If you get an error in maps.f90 you probably have the same issue as #8 (which has the solution too).

[Amaa486]

Thanks again. The message of error shrank to be:
gfortran -fopenmp -O ab.o -o ab.exe /Users/aldurayhim/Downloads/auto/07p/lib/*.o

I have followed your instruction in #8 and do the required change in line 257 in maps.f90.
Moreover, for >> fortran -v
I have received

Judging from the file stamps I suspect you may have compiled some files in July with a different Fortran compiler than you are using now. Please do

cd /Users/aldurayhim/Downloads/auto/07p
make superclean

and then recompile everything.

[Amaa486]

It is working now. Thanks bartoldeman for your great support.
