Now that the IQ32.dll is no longer required, how long before Linux is supported?

This doesn't answer your question exactly, but it might be useful information.

I've experimented with running recent versions of IQFeed on Fedora 11 using Wine 1.1.32. It generates a few error messages (mismatched CoUninitialize, if I remember rightly) but appears to function correctly and efficiently.

Since Wine isn't an emulator or a virtual machine environment, I would guess that using it to run IQConnect doesn't violate the ban on redistributing data; the data is received and used on a single real machine. However, I doubt the DTN folks have done any of the testing that would be required to make it an officially-supported platform. We'd have to ask them directly to clear up those issues.

And yes, I'd also like to see an official IQFeed client for Linux.

For what it's worth I also have ran IQFeed under wine (1.0.1) on Ubuntu. This is mainly for testing/profiling but it does seem to work rather well.

Regards,

Jeremy.

I've got IQFeed working with my own projects under Ubuntu (Karmic Koala), but having problems with OS X (lack of any official Wine client probably not a good start)..

DTN, I can understand you don't want a dozen extra test platforms, but surely you can move across to compiling to CIL and throw Ubuntu latest and a Mac into your test environment?

We want to use this feed on Mac OS X. Are there any alternatives to IQFeed which already support Mac and/or Linux?

IQFeed won't work on Mac OS as an API for your own development. The only option for IQFeed on Mac OS is with InvestorRT software. InvestorRT has a Mac OS version of their software which talks directly to our servers and thus bypasses the IQFeed windows client. Otherwise, IQFeed will run on Linux via WINE (as you discovered on another thread).

Which DTN feed did InvestorRT use for development, to connect directly to DTN servers? We have our parser written to the D8080 on the Satellite feed currently, and wish to add Options. Options were removed from satellite, so we're forced to switch.

They connect to IQFeed's servers. They have been doing this for nearly 15 years and the only option we have for developers now is utilizing the IQFeed client or NxCore for data feeds (both windows clients). We are working on a Java version of IQFeed that will be cross platform, but it is still early in development.

WINE has been ported to Mac OS X, so I'm going to give it a test drive.

Hi Jay,

Just a follow up on your comments regarding a cross platform version of IQFeed in Java.

I am assuming that IQfeed is currently written in C/C++. If so, it should be easy enough to convert to run on any platform - minus the GUI interface? I'm sure most people on Linux could cope with no GUI. If a GUI is needed, then there are plenty of cross platform GUI toolkits that could be used.

I'm not anti java, but it does add another large dependency to deploy an IQFeed based app. Then there are the "performance and memory issues" that will crop up when using the standard Java runtime. In short, the Java version is likely to be slower and use more memory.

Wouldn't the best approach be to allow application developers to connect directly to your servers using a well specified API? Would certainly reduced latency and have a few other positive benefits as well.

Cheers,

Jeremy.
