Cannot run examples #11

Closed GrauleM closed 5 years ago

GrauleM commented 5 years ago

I am struggling getting the examples to run on Ubuntu 16.04 (see below), and would highly appreciate your help. I copied all the info I could think of below. I'm on the snopt-only branch (may be related to https://github.com/snopt/snopt-python/issues/5 ).

Also, what are the exact requirements for snopt-python?

error when running example as sudo: 

mo@xx:/usr/local/snopt-python/examples$ sudo python dieta.py 

Traceback (most recent call last):
  File "dieta.py", line 7, in <module>

I believe I defined the environment variables according to your instructions:

mo@xx:/$ echo "$LD_LIBRARY_PATH" "$SNOPT7LIB" "$SNOPT_LICENSE"

/usr/local/lib/ /usr/local/lib /home/mo/Desktop/snopt7.lic

the lib folder contains:

mo@xx:/usr/local/lib$ ls

ImportError: libgfortran.so.4: cannot open shared object file: No such file or directory

We use gfortran 7.3 to compile the snopt library so you probably need to install gcc7 libraries.

GrauleM commented 5 years ago

You were right, I had a different version of gfortran installed.

Now I am getting a segmentation fault (see below) when I try to run the examples. Could you provide me with the exact specs of the system you are running this on (e.g., Ubuntu version, versions of required libraries, Python modules, ... )? I would like to set up the same system.

And just to double check: when you say 'SNOPT Fortran libraries', are you referring to the Fortran (only) Libraries or Fortran/C Libraries?

mo@xx:/usr/local/snopt-python/examples$ sudo python hs118.py 
Segmentation fault (core dumped)
gnowzil commented 5 years ago

I just made a minor update to one of the calls to a file-handling subroutine that was causing the seg fault. Verified it now works on my machine (ubuntu 18.04, gnu compiler 7.3). Either Fortran or Fortran/C library will work.

GrauleM commented 5 years ago

that fixed it, thank you!
