I have system Ruby:
% which -a ruby
/usr/bin/ruby
ruby -v
ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.x86_64-darwin23]
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
When my QT app starts first time on MacOS, its directory ./Application Support/Sharlines/Lines/ does not exit, but QT creates it when I write to QSettings first time.
To create the local directory I added the following code:
// Local data directory does not exist when the app is run first time on MacOS.
if (fs::create_directories(GetLocalFolder()))
{
qDebug() << static_cast<QString>(qtil::Format() << "Local folder '" << GetLocalFolder() << "' has been created.");
}
First I created a PHP file lines-app-store.php on sharlines.com website with the following content:
<?php
$iPod = stripos($_SERVER['HTTP_USER_AGENT'],"iPod");
$iPhone = stripos($_SERVER['HTTP_USER_AGENT'],"iPhone");
$iPad = stripos($_SERVER['HTTP_USER_AGENT'],"iPad");
$macOs = stripos($_SERVER['HTTP_USER_AGENT'],"Mac");
$Android= stripos($_SERVER['HTTP_USER_AGENT'],"Android");
//check if user is using ipod, iphone or ipad...
if( $iPod || $iPhone || $iPad || $macOs)
{
//we send these people to Apple Store
header('Location: https://apps.apple.com/app/id6504194961');
}
else if($Android)
{
//we send these people to Android Store
header('Location: https://play.google.com/store/apps/details?id=net.geographx.LinesGame');
}
else
{
//we send these people to Windows Store
header('Location: https://www.microsoft.com/ru-ru/store/p/lines-3d/9nblggh5g9c6');
}
?>
I simply opened arboreus_examples/qt6/CMake/UsingSwift/UsingSwift_v3/CMakeLists.txt in QT Creator and was able to build it and run.
In its main.cpp it creates a Swift wrapper and calls method:
ASwift* oSwift = new ASwift(&oEngine);
oSwift->mInit();
_A_DEBUG << oSwift->mString();
According to the official repository docs I tried to install CocaPods:
sudo gem install cocoapods
but got the following error:
ERROR: Error installing cocoapods:
The last version of drb (>= 0) to support your Ruby & RubyGems was 2.0.6. Try installing it with `gem install drb -v 2.0.6` and then running the current command again
drb requires Ruby version >= 2.7.0. The current ruby version is 2.6.10.210.
Installed some dependencies and the installation of CocoaPods succeeded:
sudo gem install drb -v 2.0.6
sudo gem install activesupport -v 6.1.7.8
sudo gem install cocoapods
Last time I have been working on a C++ binary serialization framework that allows to serialize simple data structures with a few lines of code. First, you add AWL_REFLECT macro to all your structures as follows:
#include "Awl/Reflection.h"
#include <string>
#include <vector>
#include <set>
struct A
{
int a;
bool b;
std::string c;
double d;
AWL_REFLECT(a, b, c, d)
};
When I switched to QT 6.7.2 and set QT_ANDROID_TARGET_SDK_VERSION "34" (that is Android 14) my QT app started to crash with the following stack traces:
