[Octave-bug-tracker] [bug #55940] [Mac] Disable App Nap, either selectively or for all of Octave

[Andrew Janke]

Follow-up Comment #52, bug #55940 (project octave):

Build failure, I'm afraid.


/Applications/Xcode-10.3.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/objc/message.h:85:1:
note: candidate function not viable: no known conversion from 'Class
_Nullable' (aka 'objc_class *') to 'id _Nullable' (aka 'objc_object *') for
1st argument
objc_msgSend(id _Nullable self, SEL _Nonnull op, ...)
^
libgui/src/octave-qobject.cc:222:5: error: use of undeclared identifier
'osx_latencycritical_activity'
    osx_latencycritical_activity = objc_msgSend (process_info,
    ^


Please revert, and let me get a working build using this change set as a patch
before committing again.

> Also, when you get around to testing, could you check whether the function
disable_app_nap needs to be  member function (even though private) of
base_qobject?  It seems like it would be simpler to have the function be a
static file local function in base_qobject.cc that is never seen outside the
file.

Oh, I think static would work fine. It's just my habit to make things member
functions, since I'm a Java-head. I'll do that instead.
