Subject: Re: [Openmama-users] NO_BRIDGE_IMPL() issue (avis is compiled/linked properly)

Hey Glen,

Hi Gigan,
This looks like the avis bridge lib isn't in being loaded for some reason
(FYI bridge libraries are dynamical *loaded* using dlopen() not
dynamically linked). Is the bridge library and the AVIS in your
DYLD_LIBRARY_PATH? Also putting mamalistenc in full verbose mode may give
more info, i.e:

./mamalistenc -m avis -v -v -v -v

As you said, OSX isn't currently supported but I do know of some people
who have tried in the past and did manage to get something up and running.

yeah, theoretically speaking there is not much of a difference in the required libs.
I installed avis in /usr/local so /usr/local/include contains the avis folder, and /usr/local/lib contains libavis
I didn't export DYLD_LIBRARY_PATH till now, but it looks like this:

GagansMacPro:c Gagan$ echo $DYLD_LIBRARY_PATH
/opt/openmama/lib:/usr/local/lib:

and changing -lmamaavisimpl to -lavis and re-compiling with Makefile -f sMakefile.sample still gets the same sort of issue.
I've tried -v -v -v -v before because will henry suggested it, but that didn't work:

GagansMacPro:c Gagan$ ./mamalistenc -m avis -v -v -v -v
Enter one symbol per line and terminate with a .
Symbol> .
Could not open MAMA avis bridge.

Given that the verbose output doesn't work, I'm really puzzled as to what is causing the issue.

Is there a way to check that the compiled libraries have everything?

FYI: I am new to the whole "trading" thing. I do not have any avis servers or anything like that setup, just the client installed.

I'm wondering why the examples say tiprv/elvin/one other oen, but do not mention avis? I assume elvin is avis but just slightly different.

In any case, is there a way to check the "integrity" of the libraries first? They must be the issue, as the programs compile fine but are failing to load the bridge.

Did you make any other changes to get it building on OSX? If so, and
provided other platforms aren't affected of course, then I'd be happy to
apply them. I can't see NYSE ever supporting this in their commercial
distribution as there isn't a demand for it with their customers, but for
the open source project additional platform support can only be a good
thing.

I agree, but I want to hold off on sharing those changes until we can ensure the build works properly.
They are small changes here and there, but most definitely should not be the reason for the error.

Hi guys,

Currently I'm on OSX and trying to build the openMAMA libs for my system.

I understand that OSX is not officially supported, but the issue I'm
experiencing is not specific to this platform.

Specifically, I build and install the avis client, copy the config_h to
the suggested directories, and proceed to build mama.

The build and linking goes fine, from what I can see, however the example
programs do *not* work.

I have compiled each one using a slightly modified Makefile.sample (no
-lrt flag or -Xlinker before the -Bstatic/-Bdynamic).

This issue is very strange, because I saw someone else had a bridge issue
but the linked library spit out an error. All I see is:

here's the dump:
