I get the following error on my Mac machine when running CS 7.12 in server mode:

thanks got the issue resolved

Information on what you did to fix it would be useful to others who might find this via google or browsing…..

Questions that might need answering for your post to be useful:

1) Is this the precompiled mac binary in BINARIES or one you compiled yourself?
2) If you compiled yourself what method did you use?
3) How did you resolve the problem?

Previously, while I was using the older version of ChatScript, I didn’t face this issue. For Chatscript 7.2, I used the precompiled MAC binary and faced the above errors. To solve the issue I had to install MongoDB C Driver and libbson-1.0.0. Later, I used the same precompiled MAC binary and got the issue resolved.
