Good afternoon Lynn, 

Thank you so much for responding and assuring I'm not the only crazy guy pulling my hair to figure out what is going on. I feel the day there is no support for LibRets (at least for Windows). We are already neck deep in this integration. It would be painful task to rewrite and doing webrequests. Is there a GitHub project I can refer to to get started and build on top of it. We need to pull listings download media / read media URL. Any suggestions related to this would be greatly appreciated!! 

Thanks again for taking time and giving your inputs!!

Hey KCZ,

Thanks for responding. I have been using same DLLs on our Windows server
2012, 2016 for over 5 years now. It was working fine until last month. This
error is intermittent doesn't happen all the time. It works just fine on
the windows server 2016 and randomly throws exception whenever it feels
like, this behavior is really strange.

I have been sitting on the sidelines reading this email chain since it began
but was reluctant in today’s social media environment to voice my thoughts.  I
had very similar symptoms in a Windows 10/64-bit system more than a year ago.
I had discussions with one of the past (and no longer involved) LibRETS
developers/maintainers and I even helped support LibRETS maintenance for some
time by donating a Visual Studio license for use by the developer. We
eventually agreed that a native .Net download mechanism was probably needed
for me to get back to reliable operation (since I am strictly a .Net
developer).  I did that using .Net and an HTTPWebRequest architecture and it
has served me well now for over a year.

LibRETS is a remarkable tool and has been for a long time, but I fear that (in
the Windows/.Net world) it is reaching the end of life.  Please, I’m not
saying this as criticism to NAR, the past (or current) developers, current
users, etc. and I’m definitely not saying it so I end up having  tens or
hundreds of people sending me unfriendly emails – please.  I’ve just had no
reliability issues since moving away from it to a native .Net solution.

I wish you the best and do hope you find a solution.

Abid,
Im not sure, but I think, you will need to use librets 64bits (no much
details in your email)

was your application running in a different server (32bits)?

your app never ran on your server windows 2016?

Abid,

 

To the best of my knowledge, LibRETS was originally written in C++ for a Linux environment.  The Windows version was lucky enough to work for a number of years and there was support for that working software, but once Windows and the hardware world got to a certain point really wasn’t a good upgrade path available to it.  The folks who have supported LibRETS in the past did the best they could trying to keep the Windows version running, but the C++/Linux foundation just doesn’t encourage that. 

 

Today, one must decide if they want to make the same commitment I did and, from my perspective, that’s not a bad thing but it can be an unwanted interruption when you are in the middle of a critical project.  I was in that position as well.

 

I have not made my interface a freebie on GitHub or any other location, mostly because I have no interest in supporting or developing it for free.  It’s not that I’m selfish or greedy but I have costs too and I cannot spend significant hours of my time in unplanned priority circumstances for free.  Neither have I decided to “jump off the cliff” of trying to market the product commercially.  I did not bring it up to you to try to encourage a sale.  I responded to your email after much delay and indecision but, in the end, my concern and empathy for your position won over my own objections and I sent the email I did to provide whatever discussion points and direction I could.

 

As kind of a counter-discussion point, have you considered installing your LibRETS download functionality on an older computer with an older operating system to see if you achieve reliable operation?  I’m not trying to be smart or cute by asking.  I just don’t know any other way around the problem, but this would only work if you were doing periodic downloads in a batch mode.  If you were planning on using LibRETS to do downloads to meet user search requests dynamically from a website server(s), then I doubt that idea would be much help.  If I may ask, which way were/are you planning on using an interface – a kind of periodic MLS-wide download or from a web server to satisfy individual web user requests?

libRETS _is_ open source. These days, it is the community that supports it
through
pull requests to the github repo. I'll be happy to commit PR that don't have
breaking changes in them. Beyond that, I've been out of the Real Estate
industry since 2012, so I leave libRETS support to others.

But, as Lynn points out, Windows is and always has been an after thought.
libRETS
was designed for Linux and Windows and other language support was bolted on
through the use of something called SWIG. I'm not a Windows developer and I
struggled mightily just to get a few builds to succeed.

Perhaps you can use a Linux machine/VM as an adaptor? Outside of that, I have
no other suggestions.

Sorry,


M.

[Abid Shaik]

Lynn, 

I really appreciate your time and effort while responding to my emails. No worries we are probably going to explore RESO's Web APIs moving forward if there is not much support for LibRets in Windows environment. 

"have you considered installing your LibRETS download functionality on an older computer" --This integration has been working on Windows server 2008, 2012 and 2016 and Windows 10 (Dev). Downgrading to older windows OS is not an option for us.   

"this would only work if you were doing periodic downloads in a batch mode" -- This is what we are doing. We don't do real time search. 

Dave, 

Thank you so much for your suggestion. I will try your approach and see how that works. This integration is in legacy app (.Net 2.0 NOT Core 2.0). Will see if those libraries you mentioned are compatible with .Net 2.0 

Thanks again for your help!! Will keep you posted how Web API integration goes.
