Error starting graywolf

[zmleitao]

I have sucessfully built and installed graywolf in CentOS 6 and Fedora 20 machines.
However, when trying to run:
$ graywolf -d
I get the following output errors:

And when trying to run:
$ graywolf -n -d
I get the following output errors:

Hi,

Thanks for reporting this!

I get the same errors apparently. Unfortuntately, I've only used graywolf in the context of qflow which runs graywolf without -n and -d , and I will not have time nor motivation to debug things which don't show up together with qflow (http://opencircuitdesign.com/qflow/). If you can provide a fix for this, I'm of course willing to accept a pull request!

Thank you

Best regards,
Ruben

Hey guys,

My message is unrelated to this issue - but thought this was the best way to get in touch with both of you. I'm attempting to use graywolf for some work related to my master's thesis - but I can't find much documentation about the code, apart from the comments. Since both of you have worked with timberwolf/graywolf, do you have access to any other sources documentation that I could use to understand the program architecture better?

Hi,

I don't know the code very well. I just did the tweaks needed to make timberwolf build as a normal linux program from source and install correctly - and then I named it graywolf. Tim at opencircuitdesign.com knows more. The documentation I've seen is in the tar-bundle of Timberwolf which can be found here: http://opencircuitdesign.com/magic/archive/timberwolf-6.3.5.tgz
However, these documents have licenses that are unclear.

Good luck with your thesis. It would be great if you find a cool use for graywolf and maybe brought some improvements back!

Regards,
Ruben

Hi Ruben,

Thanks a lot! I somehow missed the doc folder in the tar bundle.

Also like to thank you for the work on graywolf- being able to build timberwolf as a normal linux tool will alleviate some of the pain I faced in the past. I hope I'm able to execute on my ideas, would love to contribute back to graywolf if all goes well.

Sincerely,

Ariq

I'm getting the same after I successfully built everything. This is the very last step.

any solution to this?

[K0rrid0r]

SOLVED!

now this is a windows 8.1 solution.

i needed to

find . -type f -print0 | xargs -0 dos2unix

the whole map9v3 folder and also C:\cygwin64\usr\local\lib\graywolf\bin\flow folder.

then it worked :)

Several years after, I am also facing the same issue, have you solved it? Please let me know, if you have. In Q-flow synthesis step works just fine. But after that this error is occurring.

Hello, I am doing it in Linux OS, In GUI of a Q-flow, Can you tell me how have you done this? I am also facing the exact same issue!!! Thanks in Advance.
