First of all: there's no need to send the e-mail more than once...it will just make people not answering. Probably what happens is that you have the old libraries (the ones you compiled with the HEAD version of SEMS) and SEMS rel_0.8.12. Be sure the libraries are correct. Samuel Unclassified. Hi all, I'm trying to make SEMS work. First I was working with SER 0.8.14 and SEMS cvs but I always got the error consume_request(): consumed. I only want SEMS for voicemail, so the list recommended that I downloaded the SEMS rel_0.8.12, which is supposed to be compatible with SER 0.8.14, but when loading the plug-ins I get errors about undefined symbols. I've been reading previous posts and it seems that it's either an incompatibility between versions, or that SEMS is working with another version's modules or something like that. I don't know how to solve this. Here are the errors I'm getting: Configuration: configuration file: /usr/local/etc/sems/sems12.conf Ser's FIFO: /tmp/ser_fifo our FIFO: /tmp/am_fifo plug-in path: /usr/local/src/sems_rel_0_8_12/lib daemon mode: 0 local IP: 172.25.97.19 (4851) DEBUG: main (sems.cpp:386): Loading application plug-ins (4851) DEBUG: load (AmPlugIn.cpp:89): loading /usr/local/src/sems_rel_0_8_12/lib/apps/bot.so ...
