[Doxygen-users] Error in file XX.f90 line:3468, state 4

[Fabian N. <fab...@sc...>]

Hi everyone,

when trying to run doxygen on a large (Fortran-)project, I get the "Error in file XX.f90 line:3468, state 4" error. The interesting thing is that the file only has 3466 lines...
The file is in fixed format. Somewhere on the web it was said that enabling the C-preprocessor might help but it doesn't in my case. I also read that there was a bug which was fixed in version 1.5.6 (I think), however I'm using version 1.6.1.

Any advice on what I could try?

Regards,
Fabian

Hi Fabian,

The line number is the number where it saw a problem and in this case this
is when the file has been completely parsed.
The state 4 means an error with SubprogBody, so something not ended
properly (I assume the file compiles properly).

You are using version 1.6.1 and the current version is 1.8.7 so an upgrade
would certainly help.
During the run does it say something about prepassing XX.f90 ?
so like:
Reading .../XX.f90
Prepassing fixed form of .../XX.f90
Parsing file XX.f90

The line
Prepassing fixed form of .../XX.f90
should not be present, if present try to place a ! as fist line in the
XX.f90 file.

Anyhow upgrading to 1.8.7 is a very good idea.

Albert

Re: [Doxygen-users] Error in file XX.f90 line:3468, state 4

[Fabian N. <fab...@sc...>]

Hi Albert,

no the Prepassing line is not present. Just "preprocessing..." and "parsing..."
I tried the extra line starting with "!" anyway, but it didn't help.

Using 1.8.7 didn't help either, however the error is now reported in line 3467 (as opposed to 3468 before).

And yes, the file does compile properly.
Are there any constructs (like strings containing '!' in the source) I could look out for?

Regards,
Fabian

Hi Fabian,

It is always hard to find these kind of errors. What I do is that I reduce
the file and see what happens (good old trial and error removing half of
the file etc.).

Is it possible for you to post the file? (I could have a look in the
evening.

Re: [Doxygen-users] Error in file XX.f90 line:3468, state 4

[Fabian N. <fab...@sc...>]

Hi Albert,

thanks for your efforts.

Since the error only occured in one file, I think we can live with this quick fix for the time being.
We'll have to see how our usage of Doxygen develops anyway. (Our code has grown over quite some years already so it won't be easy do document everything and have a nice and clean documentation)

Regarding the EXTENSION_MAPPING parameter: I tried setting it to FortranFree but the error still occured in the "non-fixed" version of the source file.

Best regards,
Fabian

Re: [Doxygen-users] Error in file XX.f90 line:3468, state 4

[Fabian N. <fab...@sc...>]

Yes it does.

So from what I'm seeing at the moment, the old versions seem to ignore the EXTENSION_MAPPING = f90=FortranFree ?! (thus mapping f90 to Fortran)
That would be good, since per default our machines run doxygen 1.6.1 and it would be nice if we could all use the same config file...
