Re: asyn4-20 compiling error on Scientific Linux 6.1

Yep, events are now strings.

Here's the quick fix that I made to work around this problem.

Mark,

 

Compiling either asyn-4.19 or 4-20 with EPICS R3.15.0.1 on Scientific Linux 6.1 gets the following error:

 

../../asyn/devGpib/devCommonGpib.c: In function ‘evFinish’:

../../asyn/devGpib/devCommonGpib.c:475: error: incompatible types when assigning to type ‘char[40]’ from type ‘short unsigned int’

make[2]: *** [devCommonGpib.o] Error 1

make[2]: Leaving directory ‘/home/test/linux/prod/R3.15.0.1/asyn/asyn4-19/asyn/O.linux-x86’

 

The linux version is: Linux version 2.6.32-131.0.15.el6.i686 (mockbuild@spacewalk.fnal.gov) (gcc version 4.4.5 20110214 (Red Hat 4.4.5-6) (GCC) ).

 

Is there a fix for this please?

 

Jim
