QUESTION
According to this overview in order to compile Y2038 conform old code, we just need to add the preprocessor macro __USE_TIME_BITS64
to gcc
, but that does not seem to work on an ARMv7 board with Debian 12 (bookworm):
ANSWER
Answered 2022-Mar-24 at 08:49According to this post (which is getting a little old now, and some parts of which are probably no longer relevant):
... defining
_TIME_BITS=64
would cause all time functions to use 64-bit times by default. The_TIME_BITS=64
option is implemented by transparently mapping the standard functions and types to their internal 64-bit variants. Glibc would also set__USE_TIME_BITS64
, which user code can test for to determine if the 64-bit variants are available.
Presumably, this includes making time_t
64 bit.
So if your version of glibc supports this at all, it looks like you're setting the wrong macro. You want:
-D_TIME_BITS=64
QUESTION
I'm having a ton of trouble figuring out why the buttons in this won't show? They were showing up earlier today when I test ran the program but now I've been stuck for 2 hours trying to get the buttons to show up again. It's also really weird because the panel is definitely showing up because the phrase "Welcome to the BookListApp" is showing up.
...ANSWER
Answered 2022-Mar-18 at 05:36If you use an absolute layout (panel.setLayout(null);) then you have to specify the bounds of the buttons to be visible:

I dockerize an R analysis and want to have an initial Docker layer, with all the required R packages, on the top of which I am going to add the analysis script. Despite having read the various documentation and blogs I am stunned by the following behavior:

In the Bismon static source code analyzer (GPLv3+ licensed, git commit 49dd1bd232854a
) for embedded C and C++ code (using a plugin for GCC 10 straight compiler on Debian bookworm for x86-64) I have a test Bash script Hello-World-Analyze
which uses a GNU array variable bismon_hello_args
.
That variable is declared (at line 56) using:
...ANSWER
Answered 2021-Sep-20 at 08:39Merely +=
adds a string to an existing string. You probably want bismon_hello_args+=("$f");;
(notice also the quotes). To call the program, use ./bismon "${bismon_hello_args[@]}" &
(notice the quotes, again).
The syntax to use an array variable is different than the syntax for simple scalars. This syntax was inherited from ksh
, which in turn needed to find a way to introduce new behavior without sacrificing compatibility with existing Bourne shell scripts.
Without the array modifiers, Bash simply accesses the first element of the array. (This confuses beginners and experienced practitioners alike.)
QUESTION
I am working through Paul Hudson's 100 Days of SwiftUI and on Project 11 have hit a frustrating issue with CoreData. This is a direct lift of Paul's code that compiles and runs fine in his video. The Bookworm.xcdatamodeld has a single entity named Student that has two attributes: a UUID named id and a String named name.
It compiles fine, but running it results in a crash on the ForEach, with 'students' underlined in red. The error message that pops up in the console says:

I have searched a ton, and tried every recommended solution that I have found including: simply closing and reopening Xcode (Step 1), cleaning the project and then repeating Step 1, and deleting all the derived data and repeating Step 1. I have verified that Current Product Module is selected in the inspector for the Module, and that Codegen has Class Definition selected.

Answered 2020-Oct-31 at 18:09If you are using SwiftUI lifecycle, you should initialize NSPersistentContainer in a parent View (or App) and import managedObjectContext to the environment.
In your case, it could be something like this:
QUESTION
Looking to have button enter go into another screen: need help with navigation screen. I keep getting error: Cannot read property 'navigation' of undefined Evaluating App.js Loading App.js TypeError: Cannot read property 'navigation' of undefined
...ANSWER
Answered 2020-Aug-20 at 03:46In the above code snippet, I don't see a default Navigator
being returned form the entry file, which is App.js
by default in React Native.
I assume that you just started to learn React Native, so I will spare you all the minor details and walk you through the solution.
- I refactored the
App.js
file to a into a new component file in/components/Home.js
. - Added a default stack
Navigator
inApp.js
which has two screens, Home and Books. - Now you can access all the
Navigation
props in yourHome
andBooks
component, as it is being declared in the Navigator variable inApp.js
Here is a live demo of your code on Expo.

I am trying to access the IBM Watson Discovery API (Free Trial) using the piece of code below:
...ANSWER
Answered 2020-Apr-06 at 08:42As per the release notes and the response you are seeing the Preview API
was deprecated on the 4th June 2019 - https://cloud.ibm.com/docs/discovery?topic=discovery-release-notes#4jun19 - and removed on the 30 Sept 2019 - https://cloud.ibm.com/docs/discovery?topic=discovery-release-notes
The Discovery API is still available - https://cloud.ibm.com/apidocs/discovery/discovery , just not the preview method.
