Hi Andrew et al,

Congratulations on the first EPICS version > Pi release! ;-)

We made an attempt to integrate the new EPICS base into ITER's CODAC
Core System, however we did not get very far because it seems that there
is still quite some work needed to be done to EPICS modules. I haven't
spent a lot of time searching for all the problems but basically I got
stuck with asyn module which fails to compile due to some changes in
eventRecord API (i.e. it tries to assign short integer to char[40] 'val'
field of eventRecord structure).

There is some code in the asyn GPIB part that tries to access the val

field directly via a pointer and thus assumes a certain data type of

this field. The better way would be to use a DBADDR structure which

would do all necessary type conversions (like any db link is doing it).

Maybe next week I have a look into asyn. For the time being, you can

simply comment out the devGpib blocks from the asyn Makefiles (provided

you do not need davGpib support).
