Hi

 

How much is it important to set the SHRLIB_VERSION when building support modules? I know it is set by default to the base version when building EPICS base but it seems it is optional when building any support modules. I did this test in our RPM setup, I had all support modules built using asyn 4.41 and I deployed an RPM for asyn 4.42, doing “yum install stream-device” failed because it explicitly asked for asyn 4.41 “libasyn.so.4.41”. I unset the variable in the base and removed it in the support modules, it did update asyn and installed any module that uses asyn, but I am wondering how much this would affect compatibility and dependencies between modules.

 

Thanks,
