Porting things to a new PC, and my script/s are broken.  New PC is windows 10.  Trying to get standalone python working.

API files from v14.2 or thereabouts.

Here's the error after my import attempt:

System error: mgapilib not found!

Code:

try:
    from mgapilib import *
except:
    my_fatal_err('System error: mgapilib not found') 

Presagis vars:

MPI_INSTALL_DEFAULT=C:\Presagis

PRESAGIS_CREATOR=C:\Presagis\Suite16\Creator

PRESAGIS_CREATOR_16_0=C:\Presagis\Suite16\Creator

PRESAGIS_LICENSING=C:\Presagis

PRESAGIS_OPENFLIGHT_API=C:\Presagis\OpenFlight_API

PRESAGIS_OPENFLIGHT_SCRIPT=C:\Presagis\OpenFlight_API\bin\release

PRESAGIS_ROOT=C:\Presagis

PYTHONPATH=C:\Presagis\OpenFlight_API\bin\release

From the interpreter I can see:

E:\utils>python

Python 2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)] on win32

Help!

Thx

Help!  I have to resurrect this thread.

I've just uninstalled OpenFlightAPI, then  D/L & install OpenFlightAPI windows from here:

https://portal.presagis.com/support/solutions/articles/19000058654-openflight-api-16

It looks like there is some conflict between 32 and 64 bit versions (due to the error message):

C:\Presagis\Suite16\OpenFlight_API\samples>cd scripts



C:\Presagis\Suite16\OpenFlight_API\samples\scripts>python egnew1.py

Traceback (most recent call last):

  File "egnew1.py", line 26, in <module>

    from mgapilib import *

  File "C:\Presagis\Suite16\OpenFlight_API\bin_x64\release\mgapilib.py", line 7, in <module>

    import _mgapilib

ImportError: DLL load failed: %1 is not a valid Win32 application.

I don't see where my environment is pointing to the wrong library.  

PYTHONPATH=C:\Presagis\Suite16\OpenFlight_API\bin_x64\release

Tried the trick of moving out of the folder & re-running the script, same error.

This is Python 2.7.8.  BTW I am able to run 'standard' python scripts fine, just nothing 

Tried on a different script, it looks like python isn't finding mgapilib, but:

C:\Presagis\Suite16\OpenFlight_API\bin_x64\release>dir /b

fltdata.dll

mgapilib.dll

mgapilib.py

mgapilib.pyc

mgdd.dll

mgmemory.dll

mgruntime.dll

_mgapilib.pyd

There are no files in the current folder *mg* or *dll*.

Thx

This looks exactly like the original problem you had at the top of this thread. You managed to get that working, I suspect you've fallen into the same quagmire again. Review the thread to make sure you have everything set up properly.

At the end of the day, all you have to do for OpenFlight Script to work is set these two environment variables.

PYTHONPATH=C:\Presagis\Suite16\OpenFlight_API\bin_x64\release

PRESAGIS_OPENFLIGHT_SCRIPT=C:\Presagis\Suite16\OpenFlight_API\bin_x64\release

presuming you have installed OpenFlight API 16 x64 and have a 64 bit version of Python installed.

And remember after you install and reset environment variables, you MUST restart any application to pick up the new environment variables. To be safe, it's always best to:

1. Install New OpenFlight API.
   
2. Set env vars to reflect new installation.
   
3. Reboot.
   

Good luck.

Hm.

Previously I moved my cmd window location.  That seems to no longer help.

PC has been rebooted.

To be clear, the python script is sitting in a folder with no other .py scripts, and as far as I know, the error I am getting is from the API install.  The folder path is clearly bin_x64 yet the error message indicates, at a guess, a syntax error within the API.

I have made no changes to the API folder locations, not even copying my script files in there.

I do get a similar error from my script:

E:\>python sa_eggetattr2.py blip.flt

Traceback (most recent call last):

  File "sa_eggetattr2.py", line 25, in <module>

    from mgapilib import *

    import _mgapilib

ImportError: DLL load failed: %1 is not a valid Win32 application.

And running the ptest.py script:

from mgapilib import *
mgInit(None,None)
mgExit()

Shawn, the output from your python interpreter suggests it is a 32 bit version of Python.

Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit (Intel)] on win32

That will not work with a 64 bit version of the OpenFlight API. 

Either find and install a 64 bit version of Python or set 
PYTHONPATH and PRESAGIS_OPENFLIGHT_SCRIPT to the 32 bit folders of the OF API bin folder.

Indeed, that is the problem!  Thank you very much!!
