Title: aSub and C++

Simon,

It sounds like you're experiencing the same issue that I came across a while back. Apparently 'not' has been made a non-ansi reserved word. Easily fixed though, by adding the following compiler switches to your build. I placed these in my Makefile:

# The following switch is required if compiling C++
# gensub modules, as the genSubRecord structure declares
# a member 'unsigned long    not;'
# However, 'not' has been made a non-ansi reserved word
# but can be switch off as such by this compiler switch :)
USR_CXXFLAGS_DEFAULT += -fno-operator-names
USR_CXXFLAGS_DEFAULT += -pedantic

Best regards,

Hello,

I'm attempting to use some C++ code in the subroutine of an
aSub record in Epics base 3.14.10.
There is a problem compiling the subroutine due to the occurrence
of the C++ reserved word 'not' in the aSubRecord header file.

i.e.  from aSubRecord.h ...

    typedef struct aSubRecord {
       .
       .
       epicsUInt32   not;   /* Max elements in T */
       .
       .
    } aSubRecord;

Is there a way around this ?

Thanks-In-Advance
