Boost

static, Boost, static link

I propose to write a small application that will have two subdirectories. One of which will compile the executable file, and the second will contain a statically linked library.

As a result, the project will look like this.

Nov. 29, 2018, 7:10 p.m.

Boost

cpp, Boost, linking, C++, static

A small note about static linking Boost, so as not to forget.

Initial data:

  • OS Windows
  • MSVC 2017 64bit
  • Boost 1.68.0
  • CMake project
An example will be shown in the simplest version without special variable settings. Maximum default.

Здравствуйте! При статической компиляции Qt с MySQL выбрасывает:

Использую Qt 5.9.6, MySQL 5.7.23, Visual Studio 2017. Компилирую под x86 архитектуру. Все работает если использовать динамическую библиотеку libmysql.lib, но если использовать статическу библиотеку mysqlclient.lib выбрасывает ошибки.



Я создал batch файл для конфигурации Qt:


SET /P qtBuildType=Qt build type (shared/static): 
SET /P qtBuildMySqlIncludePath=MySql include path: 
SET /P qtBuildMySqlLibPath=MySql lib path: 
SET /P qtBuildOpenSSLIncludePath=OpenSSL include path: 
SET /P qtBuildOpenSSLLibPath=OpenSSL lib path: 
SET /P qtBuildPath=Enter Qt build path: 
configure.bat -debug-and-release -%qtBuildType% -opensource -nomake tools -nomake examples -no-ltcg -sql-mysql -I "%qtBuildMySqlIncludePath%" -L "%qtBuildMySqlLibPath%" MYSQL_LIBS="-lmysqlclient" -ssl -openssl -openssl-linked -I "%qtBuildOpenSSLIncludePath%" -L "%qtBuildOpenSSLLibPath%" OPENSSL_LIBS="-lUser32 -lAdvapi32 -lGdi32 -lCrypt32" OPENSSL_LIBS_DEBUG="-lssleay32MTd -llibeay32MTd" OPENSSL_LIBS_RELEASE="-lssleay32MT -llibeay32MT" -prefix "%qtBuildPath%"

Я хочу чтобы эта бибилиотека была вшита в .exe файл. Также я пробовал создавать с ней статический MFC проект для теста в VS 2017. Выбрасывает такие-же ошибки (добавил скриншот). Как думаете в чем может быть проблема? Спасибо.

QML

qml, singleton, static

The notion of static methods that are used in QML differs somewhat from the classical one in C ++, when static methods are created in the class that can be used referring to the class name, rather than to a specific object. In the case of QML, things are somewhat different. In order to use such methods in QML, which are present in the C ++ class, it is necessary to register a Singleton object that will provide the required methods, and these methods should no longer be static in themselves. They should at least be labeled with the Q_INVOKABLE macro so that they can be used in QML.

To register Singleton , you need to use the qmlRegisterSingletonType function, which in addition to the standard parameters that are passed to qmlRegisterType, you must also pass the static singletonProvider function, which you also write yourself.
