Re: missing lib mamamwmimpl

Hi Damian,
 
Another question on MAMA bridge modules - which bridge module is needed to implement a MAMA / MAMDA client for the SuperFeed Data Fabric middleware ? In this case, this means an Enterprise  MAMA client (not OpenMAMA).
 
I'm not sure if I should address this to technology sales, let me know if I should re-send.
 
thanks,
Aidan

Hi Damian,

What is the compilation error you are getting when compiling the avis middleware.

Do you have the avis middleware installed on your platform.

Make sure to follow the instructions on this link http://www.openmama.org/users/build-openmama to build the avis bridge.


Thanks,
Jacob

Hi,
 
I built and installed mama from the source for our platform. Where do I find the avis bridge to build ?
 
I tried building .../OpenMAMA-2.1/mama/c_cpp/src/c/bridge/avis, which fails to compile.
 
regards,
Aidan

Hi Damian,

I would recommend that you build the mama and the bridge shared object from the source code to your specific operating system and then make sure to export the LD_LIBRARY_PATH to the location of the shared object folder.

Thanks

Hi Damian,
 
Thanks for the response. I'm just getting up-to-speed on OpenMAMA. I tried the test program as supplied, I think this is looking for the wombat bridge. I'm not sure yet which bridge would be used, though we are looking at the NYSE SuperFeed.
 
I tried the test program for the avis bridge but also fails in locating the libmamaavisimpl. I found this lib in the bin download, but not the src download. However the bin download is Linux 64-bit, and I use 32-bit Linux.
 
So I would need to locate or build the libmamaavisimpl for 32-bit. Could you suggest how to proceed ?
 
Thanks,
Aidan

Hi Aidan, 

Which middleware are you attempting to make use of here? The NYSE Enterprise Edition will support LBM, Tibrv and WMW, but OpenMAMA presently only supports the Avis bridge out of the box (unless you've built a bridge yourself). "mwm" isn't something I'm familiar with. 

Can you try running the same command, but switching the value of the -m parameter to "-m avis", then checking the results?

Thanks, 

Damian

Hi,
 
I downloaded the OpenMAMA-2.1 source, installed and built the source on Linux (32 bit); I tried the following test program, but with the following error:
