FROM_ prepended to paths causes failures when opening files

[ghost]

I was using ASAMMDF 6.2.0 which was working OK, however, after I upgraded to 6.3.2 I keep getting errors regarding invalid paths because "FROM_" is being prepended to MDF, LDF paths and the like internally in the library. This is the kind of errors I get:

OSError: [Errno 22] Invalid argument: 'FROM_C:\\Proyectos\\xxxxxx\\xxxxxxx.ldf'

Is this a bug or I am missing something? asammdf 6.3.2 is unusable for me as it is right now, I had to roll back to 6.2.0.

@dmgant please show the complete error traceback message

Apologies for the late reply, I was on holidays, just tried today with 6.4.0 and 6.4.4 and I get past this error, however I get a new one:

The MDF file contains LIN diagnostics, not much more.

MDFValidator from Vector shows the file is fine.

I think you need the latest canmatrix version. Which version do you have right now?

[ghost]

I am using 0.9.3, which to my understanding is the latest (release). MDF looks fine, I might look at it in detail when I have the time. I tried with 6.3.0, I get the FROM_ error with that one.

[ghost]

if it helps, with 6.2.0 it works fine.

[danielhrisca]

Same venv?

[danielhrisca]

0.9.3 does not contain the ldf support. They have added this after that release, so you need to install the latest master branch from canmatrix

Thank you, will try this asap.
