libmodbus

Compiling on OpenBSD

Asked by Anibal Limón

First of all, congratulations of you good work.

I have compiled libmodbus for the OpenBSD, i had to add some guidelines for the preprocessor.
The problem of the Cgywin enviroment has the same for OpenBSD is the lack of the feature called IPTOS_LOWDELAY.

I have a question.
What are the possible impact for not include this feature?
,
If you wish to include this platform (OpenBSD) on your supported platforms, contact me, i would be happy to help.

Thanks for all.

The IPTOS_LOWDELAY goal is to provide lower latency but I think it's not really important in Modbus communications.

Yes, I'm interested to support all Open Source platforms, could you describe the way you compile the library, please?
Do you use the code from the git master branch?

I've used the stable version (2.0.3) and only modify the modbus/modbus.c file.

I haven't experience with the launchpad platform.
Do you have a channel of irc for talk more about that?

I'll send the patch to your mail.

I don't use a specific channel but I'm sometimes on freenode or gimpnet

You can create a github or a gitorious account, or push the repo on your own server.
You can also send the commit by email with git format-patch command, a simple git diff > file is also possible!
