956f7322f6build: Bump minimum Qt version to 5.11.3 (Hennadii Stepanov)e22d10b936ci: Switch from bionic to buster (Hennadii Stepanov) Pull request description: The current minimum Qt version is 5.9.5 which has been set in bitcoin/bitcoin#21286. Distro support: - centos 7 -- unsupported since bitcoin/bitcoin#23511 - centos 8 -- [5.15.2](http://mirror.centos.org/centos/8/AppStream/x86_64/os/Packages/qt5-qtbase-5.15.2-3.el8.x86_64.rpm) - buster -- [5.11.3](https://packages.debian.org/buster/libqt5core5a) - bullseye -- [5.15.2](https://packages.debian.org/bullseye/libqt5core5a) - _bionic_ -- [5.9.5](https://packages.ubuntu.com/bionic/libqt5core5a) - focal -- [5.12.8](https://packages.ubuntu.com/focal/libqt5core5a) As another Ubuntu LTS is coming soon, it seems unreasonable to stick to Qt 5.9 which support [ended](https://www.qt.io/blog/2017/06/07/renewed-qt-support-services) on 2020-05-31. Anyway, it's still possible to build Bitcoin Core GUI with depends on bionic system. Bumping the minimum Qt version allows to make code safer and more reliable, e.g.: - functor-parameter overload of [`QMetaObject::invokeMethod`](https://doc.qt.io/qt-5/qmetaobject.html#invokeMethod-4) - fixed https://bugreports.qt.io/browse/QTBUG-10907 An example of the patch using the functor-overload of `QMetaObject::invokeMethod`: ```diff --- a/src/qt/walletmodel.cpp +++ b/src/qt/walletmodel.cpp @@ -349,7 +349,7 @@ bool WalletModel::changePassphrase(const SecureString &oldPass, const SecureStri static void NotifyUnload(WalletModel* walletModel) { qDebug() << "NotifyUnload"; - bool invoked = QMetaObject::invokeMethod(walletModel, "unload"); + bool invoked = QMetaObject::invokeMethod(walletModel, &WalletModel::unload); assert(invoked); } ``` It uses the same new syntax as signal-slot connection with compile-time check. Also see bitcoin/bitcoin#16348. This PR is intended to be merged early [after](https://github.com/bitcoin/bitcoin/issues/22969) branching `23.x` off.

Controlling dependencies
|
|
------------------------
|
|
Some dependencies are not needed in all configurations. The following are some factors that affect the dependency list.
|
|
|
|
#### Options passed to `./configure`
|
|
* MiniUPnPc is not needed with `--without-miniupnpc`.
|
|
* libnatpmp is not needed with `--without-natpmp`.
|
|
* Berkeley DB is not needed with `--disable-wallet` or `--without-bdb`.
|
|
* SQLite is not needed with `--disable-wallet` or `--without-sqlite`.
|
|
* Qt is not needed with `--without-gui`.
|
|
* If the qrencode dependency is absent, QR support won't be added. To force an error when that happens, pass `--with-qrencode`.
|
|
* If the systemtap dependency is absent, USDT support won't compiled in.
|
|
* ZeroMQ is needed only with the `--with-zmq` option.
|
|
|
|
#### Other
|
|
* Not-Qt-bundled zlib is required to build the [DMG tool](../contrib/macdeploy/README.md#deterministic-macos-dmg-notes) from the libdmg-hfsplus project.
