GPIB connection problem with EPICS 7

[Miroslaw Dach via Tech-talk <tech-talk at aps.anl.gov>]

Hi All, We are migrating in ALS from Centos7 to RockyLinux8 and from EPICS 3 to EPICS 7. 0. 7 . One of our ioc which runs on Centos 7 EPICS 3. 15. 4 asyn4-30 runs fine and can access the GPIB devices via gpib gateways. The same ioc when converted

Hi All,

We are migrating in ALS from Centos7 to RockyLinux8 and from EPICS 3 to EPICS 7.0.7 .

One of our ioc which runs on Centos 7 EPICS 3.15.4 asyn4-30 runs fine and can access the GPIB devices via gpib gateways.

The same ioc when converted to EPICS 7.0.7 with  asyn-R4-42 on RockyLinux 8

reports the problem as below:

vxi11Configure ("gpibport01","gpib01",0,0.0,"gpib0",0,0)

dbLoadRecords("db/gpibport01.db")

iocInit()

I compiled the same code (with EPICS 7.0.7 with  asyn-R4-42) on centos7 and ran it on Centos7 and the error messages are identical.

Would that be a problem with  EPICS 7.0.7 and new asyn-R4-42 vs EPICS 3.15.4 asyn4-30 ?

Best Regards
